W25Q128FV
1. GENERAL DESCRIPTIONS
The W25Q128FV (128M-bit) Serial Flash memory provides a storage solution for systems with limited
space, pins and power. The 25Q series offers flexibility and performance well beyond ordinary Serial Flash
devices. They are ideal for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP)
and storing voice, text and data. The device operates on a single 2.7V to 3.6V power supply with current
consumption as low as 4mA active and 1µA for power-down. All devices are offered in space-saving
packages.
The W25Q128FV array is organized into 65,536 programmable pages of 256-bytes each. Up to 256 bytes
can be programmed at a time. Pages can be erased in groups of 16 (4KB sector erase), groups of 128
(32KB block erase), groups of 256 (64KB block erase) or the entire chip (chip erase). The W25Q128FV
has 4,096 erasable sectors and 256 erasable blocks respectively. The small 4KB sectors allow for greater
flexibility in applications that require data and parameter storage. (See Figure 2.)
The W25Q128FV support the standard Serial Peripheral Interface (SPI), Dual/Quad I/O SPI as well as 2-
clocks instruction cycle Quad Peripheral Interface (QPI): Serial Clock, Chip Select, Serial Data I/O0 (DI),
I/O1 (DO), I/O2 (/WP), and I/O3 (/HOLD). SPI clock frequencies of up to 104MHz are supported allowing
equivalent clock rates of 208MHz (104MHz x 2) for Dual I/O and 416MHz (104MHz x 4) for Quad I/O when
using the Fast Read Dual/Quad I/O and QPI instructions. These transfer rates can outperform standard
Asynchronous 8 and 16-bit Parallel Flash memories. The Continuous Read Mode allows for efficient
memory access with as few as 8-clocks of instruction-overhead to read a 24-bit address, allowing true XIP
(execute in place) operation.
A Hold pin, Write Protect pin and programmable write protection, with top or bottom array control, provide
further control flexibility. Additionally, the device supports JEDEC standard manufacturer and device ID
and SFDP Register, a 64-bit Unique Serial Number and three 256-bytes Security Registers.

W25Q128FV
4. PIN DESCRIPTIONS
4.1 Chip Select (/CS)
The SPI Chip Select (/CS) pin enables and disables device operation. When /CS is high the device is
deselected and the Serial Data Output (DO, or IO0, IO1, IO2, IO3) pins are at high impedance. When
deselected, the devices power consumption will be at standby levels unless an internal erase, program or
write status register cycle is in progress. When /CS is brought low the device will be selected, power
consumption will increase to active levels and instructions can be written to and data read from the device.
After power-up, /CS must transition from high to low before a new instruction will be accepted. The /CS
input must track the VCC supply level at power-up and power-down (see “Write Protection” and Figure
58). If needed a pull-up resister on the /CS pin can be used to accomplish this.
4.2 Serial Data Input, Output and IOs (DI, DO and IO0, IO1, IO2, IO3)
The W25Q128FV supports standard SPI, Dual SPI and Quad SPI operation. Standard SPI instructions
use the unidirectional DI (input) pin to serially write instructions, addresses or data to the device on the
rising edge of the Serial Clock (CLK) input pin. Standard SPI also uses the unidirectional DO (output) to
read data or status from the device on the falling edge of CLK.
Dual and Quad SPI instructions use the bidirectional IO pins to serially write instructions, addresses or
data to the device on the rising edge of CLK and read data or status from the device on the falling edge of
CLK. Quad SPI instructions require the non-volatile Quad Enable bit (QE) in Status Register-2 to be set.
When QE=1, the /WP pin becomes IO2 and /HOLD pin becomes IO3.
4.3 Write Protect (/WP)
The Write Protect (/WP) pin can be used to prevent the Status Register from being written. Used in
conjunction with the Status Register’s Block Protect (CMP, SEC, TB, BP2, BP1 and BP0) bits and Status
Register Protect (SRP) bits, a portion as small as a 4KB sector or the entire memory array can be
hardware protected. The /WP pin is active low. When the QE bit of Status Register-2 is set for Quad I/O,
the /WP pin function is not available since this pin is used for IO2. See Figure 1a-c for the pin
configuration of Quad I/O operation.
4.4 HOLD (/HOLD)
The /HOLD pin allows the device to be paused while it is actively selected. When /HOLD is brought low,
while /CS is low, the DO pin will be at high impedance and signals on the DI and CLK pins will be ignored
(don’t care). When /HOLD is brought high, device operation can resume. The /HOLD function can be
useful when multiple devices are sharing the same SPI signals. The /HOLD pin is active low. When the
QE bit of Status Register-2 is set for Quad I/O, the /HOLD pin function is not available since this pin is
used for IO3. See Figure 1a-c for the pin configuration of Quad I/O operation.
4.5 Serial Clock (CLK)
The SPI Serial Clock Input (CLK) pin provides the timing for serial input and output operations. ("See SPI
Operations")
4.6 Reset (/RESET)
The /RESET pin allows the device to be reset by the controller. For 8-pin packages, when QE=0, the IO3
pin can be configured either as a /HOLD pin or as a /RESET pin depending on Status Register setting.
When QE=1, the /HOLD or /RESET function is not available for 8-pin configuration. On the 16-pin SOIC
package, a dedicated /RESET pin is provided and it is independent of QE bit setting.

6. FUNCTIONAL DESCRIPTIONS
6.1 SPI / QPI Operations
Figure 3. W25Q128FV Serial Flash Memory Operation Diagram
6.1.1 Standard SPI Instructions
The W25Q128FV is accessed through an SPI compatible bus consisting of four signals: Serial Clock
(CLK), Chip Select (/CS), Serial Data Input (DI) and Serial Data Output (DO). Standard SPI instructions
use the DI input pin to serially write instructions, addresses or data to the device on the rising edge of
CLK. The DO output pin is used to read data or status from the device on the falling edge of CLK.
SPI bus operation Mode 0 (0,0) and 3 (1,1) are supported. The primary difference between Mode 0 and
Mode 3 concerns the normal state of the CLK signal when the SPI bus master is in standby and data is
not being transferred to the Serial Flash. For Mode 0, the CLK signal is normally low on the falling and
rising edges of /CS. For Mode 3, the CLK signal is normally high on the falling and rising edges of /CS.
6.1.2 Dual SPI Instructions
The W25Q128FV supports Dual SPI operation when using instructions such as “Fast Read Dual Output
(3Bh)” and “Fast Read Dual I/O (BBh)”. These instructions allow data to be transferred to or from the
device at two to three times the rate of ordinary Serial Flash devices. The Dual SPI Read instructions are
ideal for quickly downloading code to RAM upon power-up (code-shadowing) or for executing non-speed-
critical code directly from the SPI bus (XIP). When using Dual SPI instructions, the DI and DO pins
become bidirectional I/O pins: IO0 and IO1.

Revision D
W25Q128FV
6.1.3 Quad SPI Instructions
The W25Q128FV supports Quad SPI operation when using instructions such as “Fast Read Quad Output
(6Bh)”, “Fast Read Quad I/O (EBh)”, “Word Read Quad I/O (E7h)” and “Octal Word Read Quad I/O
(E3h)”. These instructions allow data to be transferred to or from the device four to six times the rate of
ordinary Serial Flash. The Quad Read instructions offer a significant improvement in continuous and
random access transfer rates allowing fast code-shadowing to RAM or execution directly from the SPI bus
(XIP). When using Quad SPI instructions the DI and DO pins become bidirectional IO0 and IO1, and the
/WP and /HOLD pins become IO2 and IO3 respectively. Quad SPI instructions require the non-volatile
Quad Enable bit (QE) in Status Register-2 to be set.
6.1.4 QPI Instructions
The W25Q128FV supports Quad Peripheral Interface (QPI) operations only when the device is switched
from Standard/Dual/Quad SPI mode to QPI mode using the “Enter QPI (38h)” instruction. The typical SPI
protocol requires that the byte-long instruction code being shifted into the device only via DI pin in eight
serial clocks. The QPI mode utilizes all four IO pins to input the instruction code, thus only two serial
clocks are required. This can significantly reduce the SPI instruction overhead and improve system
performance in an XIP environment. Standard/Dual/Quad SPI mode and QPI mode are exclusive. Only
one mode can be active at any given time. “Enter QPI (38h)” and “Exit QPI (FFh)” instructions are used to
switch between these two modes. Upon power-up or after a software reset using “Reset (99h)” instruction,
the default state of the device is Standard/Dual/Quad SPI mode. To enable QPI mode, the non-volatile
Quad Enable bit (QE) in Status Register-2 is required to be set. When using QPI instructions, the DI and
DO pins become bidirectional IO0 and IO1, and the /WP and /HOLD pins become IO2 and IO3
respectively. See Figure 3 for the device operation modes.
6.1.5 Hold Function
For Standard SPI and Dual SPI operations, the /HOLD signal allows the W25Q128FV operation to be
paused while it is actively selected (when /CS is low). The /HOLD function may be useful in cases where
the SPI data and clock signals are shared with other devices. For example, consider if the page buffer
was only partially written when a priority interrupt requires use of the SPI bus. In this case the /HOLD
function can save the state of the instruction and the data in the buffer so programming can resume where
it left off once the bus is available again. The /HOLD function is only available for standard SPI and Dual
SPI operation, not during Quad SPI or QPI. The Quad Enable Bit QE in Status Register-2 is used to
determine if the pin is used as /HOLD pin or data I/O pin. When QE=0 (factory default), the pin is /HOLD,
when QE=1, the pin will become an I/O pin, /HOLD function is no longer available.
To initiate a /HOLD condition, the device must be selected with /CS low. A /HOLD condition will activate on
the falling edge of the /HOLD signal if the CLK signal is already low. If the CLK is not already low the
/HOLD condition will activate after the next falling edge of CLK. The /HOLD condition will terminate on the
rising edge of the /HOLD signal if the CLK signal is already low. If the CLK is not already low the /HOLD
condition will terminate after the next falling edge of CLK. During a /HOLD condition, the Serial Data
Output (DO) is high impedance, and Serial Data Input (DI) and Serial Clock (CLK) are ignored. The Chip
Select (/CS) signal should be kept active (low) for the full duration of the /HOLD operation to avoid
resetting the internal logic state of the device.

W25Q128FV
6.1.6 Software Reset & Hardware /RESET pin
The W25Q128FV can be reset to the initial power-on state by a software Reset sequence, either in SPI
mode or QPI mode. This sequence must include two consecutive commands: Enable Reset (66h) &
Reset (99h). If the command sequence is successfully accepted, the device will take approximately 30uS
(tRST) to reset. No command will be accepted during the reset period.
For the WSON-8 and TFBGA package types, W25Q128FV can also be configured to utilize a hardware
/RESET pin. The HOLD/RST bit in the Status Register-3 is the configuration bit for /HOLD pin function or
RESET pin function. When HOLD/RST=0 (factory default), the pin acts as a /HOLD pin as described
above; when HOLD/RST=1, the pin acts as a /RESET pin. Drive the /RESET pin low for a minimum period
of ~1us (tRESET*) will reset the device to its initial power-on state. Any on-going Program/Erase operation
will be interrupted and data corruption may happen. While /RESET is low, the device will not accept any
command input.
If QE bit is set to 1, the /HOLD or /RESET function will be disabled, the pin will become one of the four
data I/O pins.
For the SOIC-16 package, W25Q128FV provides a dedicated /RESET pin in addition to the /HOLD (IO3)
pin as illustrated in Figure 1b. Drive the /RESET pin low for a minimum period of ~1us (tRESET*) will reset
the device to its initial power-on state. The HOLD/RST bit or QE bit in the Status Register will not affect
the function of this dedicated /RESET pin.
Hardware /RESET pin has the highest priority among all the input signals. Drive /RESET low for a
minimum period of ~1us (tRESET*) will interrupt any on-going external/internal operations, regardless the
status of other SPI signals (/CS, CLK, IOs, /WP and/or /HOLD).
Note: While a faster /RESET pulse (as short as a few hundred nanoseconds) will often reset the device, a
1us minimum is recommended to ensure reliable operation.

W25Q128FV
6.2 Write Protection
Applications that use non-volatile memory must take into consideration the possibility of noise and other
adverse system conditions that may compromise data integrity. To address this concern, the W25Q128FV
provides several means to protect the data from inadvertent writes.
6.2.1 Write Protect Features
•
•
•
•
•
•
•
•
Device resets when VCC is below threshold
Time delay write disable after Power-up
Write enable/disable instructions and automatic write disable after erase or program
Software and Hardware (/WP pin) write protection using Status Registers
Additional Individual Block/Sector Locks for array protection
Write Protection using Power-down instruction
Lock Down write protection for Status Register until the next power-up
One Time Program (OTP) write protection for array and Security Registers using Status Register*
* Note: This feature is available upon special order. Please contact Winbond for details.
Upon power-up or at power-down, the W25Q128FV will maintain a reset condition while VCC is below the
threshold value of VWI, (See Power-up Timing and Voltage Levels and Figure 43). While reset, all
operations are disabled and no instructions are recognized. During power-up and after the VCC voltage
exceeds VWI, all program and erase related instructions are further disabled for a time delay of tPUW. This
includes the Write Enable, Page Program, Sector Erase, Block Erase, Chip Erase and the Write Status
Register instructions. Note that the chip select pin (/CS) must track the VCC supply level at power-up until
the VCC-min level and tVSL time delay is reached, and it must also track the VCC supply level at power-
down to prevent adverse command sequence. If needed a pull-up resister on /CS can be used to
accomplish this.
After power-up the device is automatically placed in a write-disabled state with the Status Register Write
Enable Latch (WEL) set to a 0. A Write Enable instruction must be issued before a Page Program, Sector
Erase, Block Erase, Chip Erase or Write Status Register instruction will be accepted. After completing a
program, erase or write instruction the Write Enable Latch (WEL) is automatically cleared to a write-
disabled state of 0.
Software controlled write protection is facilitated using the Write Status Register instruction and setting the
Status Register Protect (SRP0, SRP1) and Block Protect (CMP, SEC, TB, BP[2:0]) bits. These settings
allow a portion or the entire memory array to be configured as read only. Used in conjunction with the
Write Protect (/WP) pin, changes to the Status Register can be enabled or disabled under hardware
control. See Status Register section for further information. Additionally, the Power-down instruction offers
an extra level of write protection as all instructions are ignored except for the Release Power-down
instruction.
The W25Q128FV also provides another Write Protect method using the Individual Block Locks. Each
64KB block (except the top and bottom blocks, total of 510 blocks) and each 4KB sector within the
top/bottom blocks (total of 32 sectors) are equipped with an Individual Block Lock bit. When the lock bit is
0, the corresponding sector or block can be erased or programmed; when the lock bit is set to 1, Erase or
Program commands issued to the corresponding sector or block will be ignored. When the device is
powered on, all Individual Block Lock bits will be 1, so the entire memory array is protected from
Erase/Program. An “Individual Block Unlock (39h)” instruction must be issued to unlock any specific sector
or block.
The WPS bit in Status Register-3 is used to decide which Write Protect scheme should be used. When
WPS=0 (factory default), the device will only utilize CMP, SEC, TB, BP[2:0] bits to protect specific areas of
the array; when WPS=1, the device will utilize the Individual Block Locks for write protection.

W25Q128FV
7. STATUS AND CONFIGURATION REGISTERS
Three Status and Configuration Registers are provided for W25Q128FV. The Read Status Register-1/2/3
instructions can be used to provide status on the availability of the flash memory array, whether the device
is write enabled or disabled, the state of write protection, Quad SPI setting, Security Register lock status,
Erase/Program Suspend status, output driver strength, power-up and current Address Mode. The Write
Status Register instruction can be used to configure the device write protection features, Quad SPI setting,
Security Register OTP locks, Hold/Reset functions, output driver strength and power-up Address Mode.
Write access to the Status Register is controlled by the state of the non-volatile Status Register Protect bits
(SRP0, SRP1), the Write Enable instruction, and during Standard/Dual SPI operations, the /WP pin.
7.1 Status Registers
Figure 4a. Status Register-1
7.1.1 Erase/Write In Progress (BUSY) – Status Only
BUSY is a read only bit in the status register (S0) that is set to a 1 state when the device is executing a
Page Program, Quad Page Program, Sector Erase, Block Erase, Chip Erase, Write Status Register or
Erase/Program Security Register instruction. During this time the device will ignore further instructions
except for the Read Status Register and Erase/Program Suspend instruction (see tW, tPP, tSE, tBE, and
tCE in AC Characteristics). When the program, erase or write status/security register instruction has
completed, the BUSY bit will be cleared to a 0 state indicating the device is ready for further instructions.
7.1.2 Write Enable Latch (WEL) – Status Only
Write Enable Latch (WEL) is a read only bit in the status register (S1) that is set to 1 after executing a
Write Enable Instruction. The WEL status bit is cleared to 0 when the device is write disabled. A write
disable state occurs upon power-up or after any of the following instructions: Write Disable, Page
Program, Quad Page Program, Sector Erase, Block Erase, Chip Erase, Write Status Register, Erase
Security Register and Program Security Register.
7.1.3 Block Protect Bits (BP2, BP1, BP0) – Volatile/Non-Volatile Writable
The Block Protect Bits (BP2, BP1, BP0) are non-volatile read/write bits in the status register (S4, S3, and
S2) that provide Write Protection control and status. Block Protect bits can be set using the Write Status
Register Instruction (see tW in AC characteristics). All, none or a portion of the memory array can be
protected from Program and Erase instructions (see Status Register Memory Protection table). The
factory default setting for the Block Protection Bits is 0, none of the array protected.

Revision D
W25Q128FV
7.1.4 Top/Bottom Block Protect (TB) – Volatile/Non-Volatile Writable
The non-volatile Top/Bottom bit (TB) controls if the Block Protect Bits (BP2, BP1, BP0) protect from the
Top (TB=0) or the Bottom (TB=1) of the array as shown in the Status Register Memory Protection table.
The factory default setting is TB=0. The TB bit can be set with the Write Status Register Instruction
depending on the state of the SRP0, SRP1 and WEL bits.
7.1.5 Sector/Block Protect Bit (SEC) – Volatile/Non-Volatile Writable
The non-volatile Sector/Block Protect bit (SEC) controls if the Block Protect Bits (BP2, BP1, BP0) protect
either 4KB Sectors (SEC=1) or 64KB Blocks (SEC=0) in the Top (TB=0) or the Bottom (TB=1) of the array
as shown in the Status Register Memory Protection table. The default setting is SEC=0.
7.1.6 Complement Protect (CMP) – Volatile/Non-Volatile Writable
The Complement Protect bit (CMP) is a non-volatile read/write bit in the status register (S14). It is used in
conjunction with SEC, TB, BP2, BP1 and BP0 bits to provide more flexibility for the array protection. Once
CMP is set to 1, previous array protection set by SEC, TB, BP2, BP1 and BP0 will be reversed. For
instance, when CMP=0, a top 64KB block can be protected while the rest of the array is not; when
CMP=1, the top 64KB block will become unprotected while the rest of the array become read-only. Please
refer to the Status Register Memory Protection table for details. The default setting is CMP=0.
7.1.7 Status Register Protect (SRP1, SRP0) – Volatile/Non-Volatile Writable
The Status Register Protect bits (SRP1 and SRP0) are non-volatile read/write bits in the status register
(S8 and S7). The SRP bits control the method of write protection: software protection, hardware
protection, power supply lock-down or one time programmable (OTP) protection.

7.1.8 Erase/Program Suspend Status (SUS) – Status Only
The Suspend Status bit is a read only bit in the status register (S15) that is set to 1 after executing a
Erase/Program Suspend (75h) instruction. The SUS status bit is cleared to 0 by Erase/Program Resume
(7Ah) instruction as well as a power-down, power-up cycle.
7.1.9 Security Register Lock Bits (LB3, LB2, LB1) – Volatile/Non-Volatile OTP Writable
The Security Register Lock Bits (LB3, LB2, LB1) are non-volatile One Time Program (OTP) bits in Status
Register (S13, S12, S11) that provide the write protect control and status to the Security Registers. The
default state of LB3-1 is 0, Security Registers are unlocked. LB3-1 can be set to 1 individually using the
Write Status Register instruction. LB3-1 are One Time Programmable (OTP), once it’s set to 1, the
corresponding 256-Byte Security Register will become read-only permanently.
7.1.10 Quad Enable (QE) – Volatile/Non-Volatile Writable
The Quad Enable (QE) bit is a non-volatile read/write bit in the status register (S9) that allows Quad SPI
and QPI operation. When the QE bit is set to a 0 state (factory default), the /WP pin and /HOLD are
enabled. When the QE bit is set to a 1, the Quad IO2 and IO3 pins are enabled, and /WP and /HOLD
functions are disabled.
QE bit is required to be set to a 1 before issuing an “Enter QPI (38h)” to switch the device from
Standard/Dual/Quad SPI to QPI, otherwise the command will be ignored. When the device is in QPI mode,
QE bit will remain to be 1. A “Write Status Register” command in QPI mode cannot change QE bit from a
“1” to a “0”.
WARNING: If the /WP or /HOLD pins are tied directly to the power supply or ground during
standard SPI or Dual SPI operation, the QE bit should never be set to a 1.

7.1.11 Write Protect Selection (WPS) – Volatile/Non-Volatile Writable
The WPS bit is used to select which Write Protect scheme should be used. When WPS=0, the device will
use the combination of CMP, SEC, TB, BP[2:0] bits to protect a specific area of the memory array. When
WPS=1, the device will utilize the Individual Block Locks to protect any individual sector or blocks. The
default value for all Individual Block Lock bits is 1 upon device power on or after reset.
7.1.12 Output Driver Strength (DRV1, DRV0) – Volatile/Non-Volatile Writable
The DRV1 & DRV0 bits are used to determine the output driver strength for the Read operations.

7.1.13 /HOLD or /RESET Pin Function (HOLD/RST) – Volatile/Non-Volatile Writable
The HOLD/RST bit is used to determine whether /HOLD or /RESET function should be implemented on
the hardware pin for 8-pin packages. When HOLD/RST=0 (factory default), the pin acts as /HOLD; when
HOLD/RST=1, the pin acts as /RESET. However, /HOLD or /RESET functions are only available when
QE=0. If QE is set to 1, the /HOLD and /RESET functions are disabled, the pin acts as a dedicated data
I/O pin.
7.1.14 Reserved Bits – Non Functional
There are a few reserved Status Register bits that may be read out as a “0” or “1”. It is recommended to
ignore the values of those bits. During a “Write Status Register” instruction, the Reserved Bits can be
written as “0”, but there will not be any effects.

W25Q128FV
8. INSTRUCTIONS
The Standard/Dual/Quad SPI instruction set of the W25Q128FV consists of 45 basic instructions that are
fully controlled through the SPI bus (see Instruction Set Table1-2). Instructions are initiated with the falling
edge of Chip Select (/CS). The first byte of data clocked into the DI input provides the instruction code.
Data on the DI input is sampled on the rising edge of clock with most significant bit (MSB) first.
The QPI instruction set of the W25Q128FV consists of 32 basic instructions that are fully controlled
through the SPI bus (see Instruction Set Table 3). Instructions are initiated with the falling edge of Chip
Select (/CS). The first byte of data clocked through IO[3:0] pins provides the instruction code. Data on all
four IO pins are sampled on the rising edge of clock with most significant bit (MSB) first. All QPI
instructions, addresses, data and dummy bytes are using all four IO pins to transfer every byte of data with
every two serial clocks (CLK).
Instructions vary in length from a single byte to several bytes and may be followed by address bytes, data
bytes, dummy bytes (don’t care), and in some cases, a combination. Instructions are completed with the
rising edge of edge /CS. Clock relative timing diagrams for each instruction are included in Figures 5
through 57. All read instructions can be completed after any clocked bit. However, all instructions that
Write, Program or Erase must complete on a byte boundary (/CS driven high after a full 8-bits have been
clocked) otherwise the instruction will be ignored. This feature further protects the device from inadvertent
writes. Additionally, while the memory is being programmed or erased, or when the Status Register is
being written, all instructions except for Read Status Register will be ignored until the program or erase
cycle has completed.

Notes:
1. Data bytes are shifted with Most Significant Bit first. Byte fields with data in parenthesis “( )” indicate data
output from the device on either 1, 2 or 4 IO pins.
2. The Status Register contents and Device ID will repeat continuously until /CS terminates the instruction.
3. At least one byte of data input is required for Page Program, Quad Page Program and Program Security
Registers, up to 256 bytes of data input. If more than 256 bytes of data are sent to the device, the
addressing will wrap to the beginning of the page and overwrite previously sent data.

8.2 Instruction Descriptions
8.2.1 Write Enable (06h)
The Write Enable instruction (Figure 5) sets the Write Enable Latch (WEL) bit in the Status Register to a
1. The WEL bit must be set prior to every Page Program, Quad Page Program, Sector Erase, Block
Erase, Chip Erase, Write Status Register and Erase/Program Security Registers instruction. The Write
Enable instruction is entered by driving /CS low, shifting the instruction code “06h” into the Data Input (DI)
pin on the rising edge of CLK, and then driving /CS high.

8.2.2 Write Enable for Volatile Status Register (50h)
The non-volatile Status Register bits described in section 7.1 can also be written to as volatile bits. This
gives more flexibility to change the system configuration and memory protection schemes quickly without
waiting for the typical non-volatile bit write cycles or affecting the endurance of the Status Register non-
volatile bits. To write the volatile values into the Status Register bits, the Write Enable for Volatile Status
Register (50h) instruction must be issued prior to a Write Status Register (01h) instruction. Write Enable
for Volatile Status Register instruction (Figure 6) will not set the Write Enable Latch (WEL) bit, it is only
valid for the Write Status Register instruction to change the volatile Status Register bit values.

8.2.3 Write Disable (04h)
The Write Disable instruction (Figure 7) resets the Write Enable Latch (WEL) bit in the Status Register to
a 0. The Write Disable instruction is entered by driving /CS low, shifting the instruction code “04h” into the
DI pin and then driving /CS high. Note that the WEL bit is automatically reset after Power-up and upon
completion of the Write Status Register, Erase/Program Security Registers, Page Program, Quad Page
Program, Sector Erase, Block Erase, Chip Erase and Reset instructions.

8.2.4 Read Status Register-1 (05h), Status Register-2 (35h) & Status Register-3 (15h)
The Read Status Register instructions allow the 8-bit Status Registers to be read. The instruction is
entered by driving /CS low and shifting the instruction code “05h” for Status Register-1, “35h” for Status
Register-2 or “15h” for Status Register-3 into the DI pin on the rising edge of CLK. The status register bits
are then shifted out on the DO pin at the falling edge of CLK with most significant bit (MSB) first as shown
in Figure 8. Refer to section 7.1 for Status Register descriptions.
The Read Status Register instruction may be used at any time, even while a Program, Erase or Write
Status Register cycle is in progress. This allows the BUSY status bit to be checked to determine when the
cycle is complete and if the device can accept another instruction. The Status Register can be read
continuously, as shown in Figure 8. The instruction is completed by driving /CS high.

W25Q128FV
Figure 8b. Read Status Register Instruction (QPI Mode)
8.2.5
Write Status Register-1 (01h), Status Register-2 (31h) & Status Register-3 (11h)
The Write Status Register instruction allows the Status Registers to be written. The writable Status
Register bits include: SRP0, SEC, TB, BP[2:0] in Status Register-1; CMP, LB[3:1], QE, SRP1 in Status
Register-2; HOLD/RST, DRV1, DRV0, WPS & ADP in Status Register-3. All other Status Register bit
locations are read-only and will not be affected by the Write Status Register instruction. LB[3:1] are non-
volatile OTP bits, once it is set to 1, it cannot be cleared to 0.
To write non-volatile Status Register bits, a standard Write Enable (06h) instruction must previously have
been executed for the device to accept the Write Status Register instruction (Status Register bit WEL
must equal 1). Once write enabled, the instruction is entered by driving /CS low, sending the instruction
code “01h/31h/11h”, and then writing the status register data byte as illustrated in Figure 9a & 9b.
To write volatile Status Register bits, a Write Enable for Volatile Status Register (50h) instruction must
have been executed prior to the Write Status Register instruction (Status Register bit WEL remains 0).
However, SRP1 and LB[3:1] cannot be changed from “1” to “0” because of the OTP protection for these
bits. Upon power off or the execution of a Software/Hardware Reset, the volatile Status Register bit values
will be lost, and the non-volatile Status Register bit values will be restored.
During non-volatile Status Register write operation (06h combined with 01h/31h/11h), after /CS is driven
high, the self-timed Write Status Register cycle will commence for a time duration of tW (See AC
Characteristics). While the Write Status Register cycle is in progress, the Read Status Register instruction
may still be accessed to check the status of the BUSY bit. The BUSY bit is a 1 during the Write Status
Register cycle and a 0 when the cycle is finished and ready to accept other instructions again. After the
Write Status Register cycle has finished, the Write Enable Latch (WEL) bit in the Status Register will be
cleared to 0.

Revision D
W25Q128FV
During volatile Status Register write operation (50h combined with 01h/31h/11h), after /CS is driven high,
the Status Register bits will be refreshed to the new values within the time period of tSHSL2 (See AC
Characteristics). BUSY bit will remain 0 during the Status Register bit refresh period.
The Write Status Register instruction can be used in both SPI mode and QPI mode. However, the QE bit
cannot be written to when the device is in the QPI mode, because QE=1 is required for the device to enter
and operate in the QPI mode.
Refer to section 7.1 for Status Register descriptions.

W25Q128FV
The W25Q128FV is also backward compatible to Winbond’s previous generations of serial flash
memories, in which the Status Register-1&2 can be written using a single “Write Status Register-1 (01h)”
command. To complete the Write Status Register-1&2 instruction, the /CS pin must be driven high after
the sixteenth bit of data that is clocked in as shown in Figure 9c & 9d. If /CS is driven high after the eighth
clock, the Write Status Register-1 (01h) instruction will only program the Status Register-1, the Status
Register-2 will not be affected (Previous generations will clear CMP and QE bits).

8.2.6 Read Data (03h)
The Read Data instruction allows one or more data bytes to be sequentially read from the memory. The
instruction is initiated by driving the /CS pin low and then shifting the instruction code “03h” followed by a
24-bit address (A23-A0) into the DI pin. The code and address bits are latched on the rising edge of the
CLK pin. After the address is received, the data byte of the addressed memory location will be shifted out
on the DO pin at the falling edge of CLK with most significant bit (MSB) first. The address is automatically
incremented to the next higher address after each byte of data is shifted out allowing for a continuous
stream of data. This means that the entire memory can be accessed with a single instruction as long as
the clock continues. The instruction is completed by driving /CS high.
The Read Data instruction sequence is shown in Figure 14. If a Read Data instruction is issued while an
Erase, Program or Write cycle is in process (BUSY=1) the instruction is ignored and will not have any
effects on the current cycle. The Read Data instruction allows clock rates from D.C. to a maximum of fR
(see AC Electrical Characteristics).
The Read Data (03h) instruction is only supported in Standard SPI mode.

8.2.7 Fast Read (0Bh)
The Fast Read instruction is similar to the Read Data instruction except that it can operate at the highest
possible frequency of FR (see AC Electrical Characteristics). This is accomplished by adding eight
“dummy” clocks after the 24-bit address as shown in Figure 16. The dummy clocks allow the devices
internal circuits additional time for setting up the initial address. During the dummy clocks the data value
on the DO pin is a “don’t care”.

Fast Read (0Bh) in QPI Mode
The Fast Read instruction is also supported in QPI mode. When QPI mode is enabled, the number of
dummy clocks is configured by the “Set Read Parameters (C0h)” instruction to accommodate a wide
range of applications with different needs for either maximum Fast Read frequency or minimum data
access latency. Depending on the Read Parameter Bits P[5:4] setting, the number of dummy clocks can
be configured as either 2, 4, 6 or 8. The default number of dummy clocks upon power up or after a Reset
instruction is 2.

8.2.8 Fast Read Dual Output (3Bh)
The Fast Read Dual Output (3Bh) instruction is similar to the standard Fast Read (0Bh) instruction except
that data is output on two pins; IO0 and IO1. This allows data to be transferred at twice the rate of standard
SPI devices. The Fast Read Dual Output instruction is ideal for quickly downloading code from Flash to
RAM upon power-up or for applications that cache code-segments to RAM for execution.
Similar to the Fast Read instruction, the Fast Read Dual Output instruction can operate at the highest
possible frequency of FR (see AC Electrical Characteristics). This is accomplished by adding eight
“dummy” clocks after the 24-bit address as shown in Figure 18. The dummy clocks allow the device's
internal circuits additional time for setting up the initial address. The input data during the dummy clocks is
“don’t care”. However, the IO0 pin should be high-impedance prior to the falling edge of the first data out
clock.

8.2.9 Fast Read Quad Output (6Bh)
The Fast Read Quad Output (6Bh) instruction is similar to the Fast Read Dual Output (3Bh) instruction
except that data is output on four pins, IO0, IO1, IO2, and IO3. The Quad Enable (QE) bit in Status
Register-2 must be set to 1 before the device will accept the Fast Read Quad Output Instruction. The Fast
Read Quad Output Instruction allows data to be transferred at four times the rate of standard SPI devices.
The Fast Read Quad Output instruction can operate at the highest possible frequency of FR (see AC
Electrical Characteristics). This is accomplished by adding eight “dummy” clocks after the 24-bit address
as shown in Figure 20. The dummy clocks allow the device's internal circuits additional time for setting up
the initial address. The input data during the dummy clocks is “don’t care”. However, the IO pins should be
high-impedance prior to the falling edge of the first data out clock.

8.2.10 Fast Read Dual I/O (BBh)
The Fast Read Dual I/O (BBh) instruction allows for improved random access while maintaining two IO
pins, IO0 and IO1. It is similar to the Fast Read Dual Output (3Bh) instruction but with the capability to input
the Address bits (A23-0) two bits per clock. This reduced instruction overhead may allow for code
execution (XIP) directly from the Dual SPI in some applications.
Fast Read Dual I/O with “Continuous Read Mode”
The Fast Read Dual I/O instruction can further reduce instruction overhead through setting the
“Continuous Read Mode” bits (M7-0) after the input Address bits (A23-0), as shown in Figure 22a. The
upper nibble of the (M7-4) controls the length of the next Fast Read Dual I/O instruction through the
inclusion or exclusion of the first byte instruction code. The lower nibble bits of the (M3-0) are don’t care
(“x”). However, the IO pins should be high-impedance prior to the falling edge of the first data out clock.
If the “Continuous Read Mode” bits M5-4 = (1,0), then the next Fast Read Dual I/O instruction (after /CS is
raised and then lowered) does not require the BBh instruction code, as shown in Figure 22b. This reduces
the instruction sequence by eight clocks and allows the Read address to be immediately entered after /CS
is asserted low. If the “Continuous Read Mode” bits M5-4 do not equal to (1,0), the next instruction (after
/CS is raised and then lowered) requires the first byte instruction code, thus returning to normal operation.
It is recommended to input FFFFh on IO0 for the next instruction (16 clocks), to ensure M4 = 1 and return
the device to normal operation.

8.2.11 Fast Read Quad I/O (EBh)
The Fast Read Quad I/O (EBh) instruction is similar to the Fast Read Dual I/O (BBh) instruction except
that address and data bits are input and output through four pins IO0, IO1, IO2 and IO3 and four Dummy
clocks are required in SPI mode prior to the data output. The Quad I/O dramatically reduces instruction
overhead allowing faster random access for code execution (XIP) directly from the Quad SPI. The Quad
Enable bit (QE) of Status Register-2 must be set to enable the Fast Read Quad I/O Instruction.
Fast Read Quad I/O with “Continuous Read Mode”
The Fast Read Quad I/O instruction can further reduce instruction overhead through setting the
“Continuous Read Mode” bits (M7-0) after the input Address bits (A23-0), as shown in Figure 24a. The
upper nibble of the (M7-4) controls the length of the next Fast Read Quad I/O instruction through the
inclusion or exclusion of the first byte instruction code. The lower nibble bits of the (M3-0) are don’t care
(“x”). However, the IO pins should be high-impedance prior to the falling edge of the first data out clock.
If the “Continuous Read Mode” bits M5-4 = (1,0), then the next Fast Read Quad I/O instruction (after /CS
is raised and then lowered) does not require the EBh instruction code, as shown in Figure 24b. This
reduces the instruction sequence by eight clocks and allows the Read address to be immediately entered
after /CS is asserted low. If the “Continuous Read Mode” bits M5-4 do not equal to (1,0), the next
instruction (after /CS is raised and then lowered) requires the first byte instruction code, thus returning to
normal operation. It is recommended to input FFh on IO0 for the next instruction (8 clocks), to ensure M4
= 1 and return the device to normal operation.

Figure 24b. Fast Read Quad I/O Instruction (Previous instruction set M5-4 = 10, SPI Mode)
Fast Read Quad I/O with “8/16/32/64-Byte Wrap Around” in Standard SPI mode
The Fast Read Quad I/O instruction can also be used to access a specific portion within a page by issuing
a “Set Burst with Wrap” (77h) command prior to EBh. The “Set Burst with Wrap” (77h) command can
either enable or disable the “Wrap Around” feature for the following EBh commands. When “Wrap
Around” is enabled, the data being accessed can be limited to either an 8, 16, 32 or 64-byte section of a
256-byte page. The output data starts at the initial address specified in the instruction, once it reaches the
ending boundary of the 8/16/32/64-byte section, the output will wrap around to the beginning boundary
automatically until /CS is pulled high to terminate the command.
The Burst with Wrap feature allows applications that use cache to quickly fetch a critical address and then
fill the cache afterwards within a fixed length (8/16/32/64-byte) of data without issuing multiple read
commands.
The “Set Burst with Wrap” instruction allows three “Wrap Bits”, W6-4 to be set. The W4 bit is used to
enable or disable the “Wrap Around” operation while W6-5 are used to specify the length of the wrap
around section within a page. Refer to section 8.2.24 for detail descriptions.

Fast Read Quad I/O (EBh) in QPI Mode
The Fast Read Quad I/O instruction is also supported in QPI mode, as shown in Figure 19c. When QPI
mode is enabled, the number of dummy clocks is configured by the “Set Read Parameters (C0h)”
instruction to accommodate a wide range of applications with different needs for either maximum Fast
Read frequency or minimum data access latency. Depending on the Read Parameter Bits P[5:4] setting,
the number of dummy clocks can be configured as either 2, 4, 6 or 8. The default number of dummy
clocks upon power up or after a Reset instruction is 2. In QPI mode, the “Continuous Read Mode” bits M7-
0 are also considered as dummy clocks. In the default setting, the data output will follow the Continuous
Read Mode bits immediately.
“Continuous Read Mode” feature is also available in QPI mode for Fast Read Quad I/O instruction. Please
refer to the description on previous pages.
“Wrap Around” feature is not available in QPI mode for Fast Read Quad I/O instruction. To perform a read
operation with fixed data length wrap around in QPI mode, a dedicated “Burst Read with Wrap” (0Ch)
instruction must be used. Please refer to 8.2.45 for details.

8.2.12 Word Read Quad I/O (E7h)
The Word Read Quad I/O (E7h) instruction is similar to the Fast Read Quad I/O (EBh) instruction except
that the lowest Address bit (A0) must equal 0 and only two Dummy clocks are required prior to the data
output. The Quad I/O dramatically reduces instruction overhead allowing faster random access for code
execution (XIP) directly from the Quad SPI. The Quad Enable bit (QE) of Status Register-2 must be set to
enable the Word Read Quad I/O Instruction.
Word Read Quad I/O with “Continuous Read Mode”
The Word Read Quad I/O instruction can further reduce instruction overhead through setting the
“Continuous Read Mode” bits (M7-0) after the input Address bits (A23-0), as shown in Figure 26a. The
upper nibble of the (M7-4) controls the length of the next Fast Read Quad I/O instruction through the
inclusion or exclusion of the first byte instruction code. The lower nibble bits of the (M3-0) are don’t care
(“x”). However, the IO pins should be high-impedance prior to the falling edge of the first data out clock.
If the “Continuous Read Mode” bits M5-4 = (1,0), then the next Fast Read Quad I/O instruction (after /CS
is raised and then lowered) does not require the E7h instruction code, as shown in Figure 26b. This
reduces the instruction sequence by eight clocks and allows the Read address to be immediately entered
after /CS is asserted low. If the “Continuous Read Mode” bits M5-4 do not equal to (1,0), the next
instruction (after /CS is raised and then lowered) requires the first byte instruction code, thus returning to
normal operation. It is recommended to input FFh on IO0 for the next instruction (8 clocks), to ensure M4
= 1 and return the device to normal operation.

256-byte page. The output data starts at the initial address specified in the instruction, once it reaches the
ending boundary of the 8/16/32/64-byte section, the output will wrap around to the beginning boundary
automatically until /CS is pulled high to terminate the command.
The Burst with Wrap feature allows applications that use cache to quickly fetch a critical address and then
fill the cache afterwards within a fixed length (8/16/32/64-byte) of data without issuing multiple read
commands.
The “Set Burst with Wrap” instruction allows three “Wrap Bits”, W6-4 to be set. The W4 bit is used to
enable or disable the “Wrap Around” operation while W6-5 are used to specify the length of the wrap
around section within a page. See 8.2.24 for detail descriptions.

8.2.13 Octal Word Read Quad I/O (E3h)
The Octal Word Read Quad I/O (E3h) instruction is similar to the Fast Read Quad I/O (EBh) instruction
except that the lower four Address bits (A0, A1, A2, A3) must equal 0. As a result, the dummy clocks are
not required, which further reduces the instruction overhead allowing even faster random access for code
execution (XIP). The Quad Enable bit (QE) of Status Register-2 must be set to enable the Octal Word
Read Quad I/O Instruction.
Octal Word Read Quad I/O with “Continuous Read Mode”
The Octal Word Read Quad I/O instruction can further reduce instruction overhead through setting the
“Continuous Read Mode” bits (M7-0) after the input Address bits (A23-0), as shown in Figure 27a. The
upper nibble of the (M7-4) controls the length of the next Octal Word Read Quad I/O instruction through
the inclusion or exclusion of the first byte instruction code. The lower nibble bits of the (M3-0) are don’t
care (“x”). However, the IO pins should be high-impedance prior to the falling edge of the first data out
clock.
If the “Continuous Read Mode” bits M5-4 = (1,0), then the next Fast Read Quad I/O instruction (after /CS
is raised and then lowered) does not require the E3h instruction code, as shown in Figure 27b. This
reduces the instruction sequence by eight clocks and allows the Read address to be immediately entered
after /CS is asserted low. If the “Continuous Read Mode” bits M5-4 do not equal to (1,0), the next
instruction (after /CS is raised and then lowered) requires the first byte instruction code, thus returning to
normal operation. It is recommended to input FFh on IO0 for the next instruction (8 clocks), to ensure M4
= 1 and return the device to normal operation.

8.2.14 Set Burst with Wrap (77h)
In Standard SPI mode, the Set Burst with Wrap (77h) instruction is used in conjunction with “Fast Read
Quad I/O” and “Word Read Quad I/O” instructions to access a fixed length of 8/16/32/64-byte section
within a 256-byte page. Certain applications can benefit from this feature and improve the overall system
code execution performance.
Similar to a Quad I/O instruction, the Set Burst with Wrap instruction is initiated by driving the /CS pin low
and then shifting the instruction code “77h” followed by 24 dummy bits and 8 “Wrap Bits”, W7-0. The
instruction sequence is shown in Figure 28. Wrap bit W7 and the lower nibble W3-0 are not used.

Once W6-4 is set by a Set Burst with Wrap instruction, all the following “Fast Read Quad I/O” and “Word

page. To exit the “Wrap Around” function and return to normal read operation, another Set Burst with
Wrap instruction should be issued to set W4 = 1. The default value of W4 upon power on or after a
software/hardware reset is 1.
In QPI mode, the “Burst Read with Wrap (0Ch)” instruction should be used to perform the Read operation
with “Wrap Around” feature. The Wrap Length set by W5-4 in Standard SPI mode is still valid in QPI mode
and can also be re-configured by “Set Read Parameters (C0h)” instruction. Refer to 8.2.44 and 8.2.45 for
details.

8.2.15 Page Program (02h)
The Page Program instruction allows from one byte to 256 bytes (a page) of data to be programmed at
previously erased (FFh) memory locations. A Write Enable instruction must be executed before the device
will accept the Page Program Instruction (Status Register bit WEL= 1). The instruction is initiated by
driving the /CS pin low then shifting the instruction code “02h” followed by a 24-bit address (A23-A0) and
at least one data byte, into the DI pin. The /CS pin must be held low for the entire length of the instruction
while data is being sent to the device. The Page Program instruction sequence is shown in Figure 29.
If an entire 256 byte page is to be programmed, the last address byte (the 8 least significant address bits)
should be set to 0. If the last address byte is not zero, and the number of clocks exceeds the remaining
page length, the addressing will wrap to the beginning of the page. In some cases, less than 256 bytes (a
partial page) can be programmed without having any effect on other bytes within the same page. One
condition to perform a partial page program is that the number of clocks cannot exceed the remaining
page length. If more than 256 bytes are sent to the device the addressing will wrap to the beginning of the
page and overwrite previously sent data.
As with the write and erase instructions, the /CS pin must be driven high after the eighth bit of the last byte
has been latched. If this is not done the Page Program instruction will not be executed. After /CS is driven
high, the self-timed Page Program instruction will commence for a time duration of tpp (See AC
Characteristics). While the Page Program cycle is in progress, the Read Status Register instruction may
still be accessed for checking the status of the BUSY bit. The BUSY bit is a 1 during the Page Program
cycle and becomes a 0 when the cycle is finished and the device is ready to accept other instructions
again. After the Page Program cycle has finished the Write Enable Latch (WEL) bit in the Status Register
is cleared to 0. The Page Program instruction will not be executed if the addressed page is protected by
the Block Protect (CMP, SEC, TB, BP2, BP1, and BP0) bits or the Individual Block/Sector Locks.

8.2.16 Quad Input Page Program (32h)
The Quad Page Program instruction allows up to 256 bytes of data to be programmed at previously
erased (FFh) memory locations using four pins: IO0, IO1, IO2, and IO3. The Quad Page Program can
improve performance for PROM Programmer and applications that have slow clock speeds <5MHz.
Systems with faster clock speed will not realize much benefit for the Quad Page Program instruction since
the inherent page program time is much greater than the time it take to clock-in the data.
To use Quad Page Program the Quad Enable (QE) bit in Status Register-2 must be set to 1. A Write
Enable instruction must be executed before the device will accept the Quad Page Program instruction
(Status Register-1, WEL=1). The instruction is initiated by driving the /CS pin low then shifting the
instruction code “32h” followed by a 24-bit address (A23-A0) and at least one data byte, into the IO pins.
The /CS pin must be held low for the entire length of the instruction while data is being sent to the device.
All other functions of Quad Page Program are identical to standard Page Program. The Quad Page
Program instruction sequence is shown in Figure 30.

8.2.17 Sector Erase (20h)
The Sector Erase instruction sets all memory within a specified sector (4K-bytes) to the erased state of all
1s (FFh). A Write Enable instruction must be executed before the device will accept the Sector Erase
Instruction (Status Register bit WEL must equal 1). The instruction is initiated by driving the /CS pin low
and shifting the instruction code “20h” followed a 24-bit sector address (A23-A0). The Sector Erase
instruction sequence is shown in Figure 31a & 31b.
The /CS pin must be driven high after the eighth bit of the last byte has been latched. If this is not done the
Sector Erase instruction will not be executed. After /CS is driven high, the self-timed Sector Erase
instruction will commence for a time duration of tSE (See AC Characteristics). While the Sector Erase
cycle is in progress, the Read Status Register instruction may still be accessed for checking the status of
the BUSY bit. The BUSY bit is a 1 during the Sector Erase cycle and becomes a 0 when the cycle is
finished and the device is ready to accept other instructions again. After the Sector Erase cycle has
finished the Write Enable Latch (WEL) bit in the Status Register is cleared to 0. The Sector Erase
instruction will not be executed if the addressed page is protected by the Block Protect (CMP, SEC, TB,
BP2, BP1, and BP0) bits or the Individual Block/Sector Locks.

8.2.18 32KB Block Erase (52h)
The Block Erase instruction sets all memory within a specified block (32K-bytes) to the erased state of all
1s (FFh). A Write Enable instruction must be executed before the device will accept the Block Erase
Instruction (Status Register bit WEL must equal 1). The instruction is initiated by driving the /CS pin low
and shifting the instruction code “52h” followed a 24-bit block address (A23-A0). The Block Erase
instruction sequence is shown in Figure 32a & 32b.
The /CS pin must be driven high after the eighth bit of the last byte has been latched. If this is not done the
Block Erase instruction will not be executed. After /CS is driven high, the self-timed Block Erase instruction
will commence for a time duration of tBE1 (See AC Characteristics). While the Block Erase cycle is in
progress, the Read Status Register instruction may still be accessed for checking the status of the BUSY
bit. The BUSY bit is a 1 during the Block Erase cycle and becomes a 0 when the cycle is finished and the
device is ready to accept other instructions again. After the Block Erase cycle has finished the Write

8.2.19 64KB Block Erase (D8h)
The Block Erase instruction sets all memory within a specified block (64K-bytes) to the erased state of all
1s (FFh). A Write Enable instruction must be executed before the device will accept the Block Erase
Instruction (Status Register bit WEL must equal 1). The instruction is initiated by driving the /CS pin low
and shifting the instruction code “D8h” followed a 24-bit block address (A23-A0). The Block Erase
instruction sequence is shown in Figure 33a & 33b.
The /CS pin must be driven high after the eighth bit of the last byte has been latched. If this is not done the
Block Erase instruction will not be executed. After /CS is driven high, the self-timed Block Erase instruction
will commence for a time duration of tBE (See AC Characteristics). While the Block Erase cycle is in
progress, the Read Status Register instruction may still be accessed for checking the status of the BUSY
bit. The BUSY bit is a 1 during the Block Erase cycle and becomes a 0 when the cycle is finished and the

8.2.20 Chip Erase (C7h / 60h)
The Chip Erase instruction sets all memory within the device to the erased state of all 1s (FFh). A Write
Enable instruction must be executed before the device will accept the Chip Erase Instruction (Status
Register bit WEL must equal 1). The instruction is initiated by driving the /CS pin low and shifting the
instruction code “C7h” or “60h”. The Chip Erase instruction sequence is shown in Figure 34.
The /CS pin must be driven high after the eighth bit has been latched. If this is not done the Chip Erase
instruction will not be executed. After /CS is driven high, the self-timed Chip Erase instruction will
commence for a time duration of tCE (See AC Characteristics). While the Chip Erase cycle is in progress,
the Read Status Register instruction may still be accessed to check the status of the BUSY bit. The BUSY
bit is a 1 during the Chip Erase cycle and becomes a 0 when finished and the device is ready to accept
other instructions again. After the Chip Erase cycle has finished the Write Enable Latch (WEL) bit in the
Status Register is cleared to 0. The Chip Erase instruction will not be executed if any memory region is
protected by the Block Protect (CMP, SEC, TB, BP2, BP1, and BP0) bits or the Individual Block/Sector
Locks.

8.2.21 Erase / Program Suspend (75h)
The Erase/Program Suspend instruction “75h”, allows the system to interrupt a Sector or Block Erase
operation or a Page Program operation and then read from or program/erase data to, any other sectors or
blocks. The Erase/Program Suspend instruction sequence is shown in Figure 35a & 35b.
The Write Status Register instruction (01h) and Erase instructions (20h, 52h, D8h, C7h, 60h, 44h) are not
allowed during Erase Suspend. Erase Suspend is valid only during the Sector or Block erase operation. If
written during the Chip Erase operation, the Erase Suspend instruction is ignored. The Write Status
Register instructions (01h, 31h, 11h) and Program instructions (02h, 32h, 42h) are not allowed during
Program Suspend. Program Suspend is valid only during the Page Program or Quad Page Program
operation.
The Erase/Program Suspend instruction “75h” will be accepted by the device only if the SUS bit in the
Status Register equals to 0 and the BUSY bit equals to 1 while a Sector or Block Erase or a Page
Program operation is on-going. If the SUS bit equals to 1 or the BUSY bit equals to 0, the Suspend
instruction will be ignored by the device. A maximum of time of “tSUS” (See AC Characteristics) is required
to suspend the erase or program operation. The BUSY bit in the Status Register will be cleared from 1 to
0 within “tSUS” and the SUS bit in the Status Register will be set from 0 to 1 immediately after
Erase/Program Suspend. For a previously resumed Erase/Program operation, it is also required that the
Suspend instruction “75h” is not issued earlier than a minimum of time of “tSUS” following the preceding
Resume instruction “7Ah”.
Unexpected power off during the Erase/Program suspend state will reset the device and release the
suspend state. SUS bit in the Status Register will also reset to 0. The data within the page, sector or block

design techniques against the accidental power interruption and preserve data integrity during
erase/program suspend state.

8.2.22 Erase / Program Resume (7Ah)
The Erase/Program Resume instruction “7Ah” must be written to resume the Sector or Block Erase
operation or the Page Program operation after an Erase/Program Suspend. The Resume instruction “7Ah”
will be accepted by the device only if the SUS bit in the Status Register equals to 1 and the BUSY bit
equals to 0. After issued the SUS bit will be cleared from 1 to 0 immediately, the BUSY bit will be set from
0 to 1 within 200ns and the Sector or Block will complete the erase operation or the page will complete the
program operation. If the SUS bit equals to 0 or the BUSY bit equals to 1, the Resume instruction “7Ah”
will be ignored by the device. The Erase/Program Resume instruction sequence is shown in Figure 36a &
36b.
Resume instruction is ignored if the previous Erase/Program Suspend operation was interrupted by
unexpected power off. It is also required that a subsequent Erase/Program Suspend instruction not to be
issued within a minimum of time of “tSUS” following a previous Resume instruction.

8.2.23 Power-down (B9h)
Although the standby current during normal operation is relatively low, standby current can be further
reduced with the Power-down instruction. The lower power consumption makes the Power-down
instruction especially useful for battery powered applications (See ICC1 and ICC2 in AC Characteristics).
The instruction is initiated by driving the /CS pin low and shifting the instruction code “B9h” as shown in
Figure 37a & 37b.
The /CS pin must be driven high after the eighth bit has been latched. If this is not done the Power-down
instruction will not be executed. After /CS is driven high, the power-down state will entered within the time
duration of tDP (See AC Characteristics). While in the power-down state only the Release Power-down /
Device ID (ABh) instruction, which restores the device to normal operation, will be recognized. All other
instructions are ignored. This includes the Read Status Register instruction, which is always available
during normal operation. Ignoring all but one instruction makes the Power Down state a useful condition
for securing maximum write protection. The device always powers-up in the normal operation with the
standby current of ICC1.

8.2.24 Release Power-down / Device ID (ABh)
The Release from Power-down / Device ID instruction is a multi-purpose instruction. It can be used to
release the device from the power-down state, or obtain the devices electronic identification (ID) number.
To release the device from the power-down state, the instruction is issued by driving the /CS pin low,
shifting the instruction code “ABh” and driving /CS high as shown in Figure 38a & 38b. Release from
power-down will take the time duration of tRES1 (See AC Characteristics) before the device will resume
normal operation and other instructions are accepted. The /CS pin must remain high during the tRES1 time
duration.
When used only to obtain the Device ID while not in the power-down state, the instruction is initiated by
driving the /CS pin low and shifting the instruction code “ABh” followed by 3-dummy bytes. The Device ID
bits are then shifted out on the falling edge of CLK with most significant bit (MSB) first. The Device ID
value for the W25Q128FV is listed in Manufacturer and Device Identification table. The Device ID can be
read continuously. The instruction is completed by driving /CS high.
When used to release the device from the power-down state and obtain the Device ID, the instruction is
the same as previously described, and shown in Figure 38c & 38d, except that after /CS is driven high it
must remain high for a time duration of tRES2 (See AC Characteristics). After this time duration the device
will resume normal operation and other instructions will be accepted. If the Release from Power-down /
Device ID instruction is issued while an Erase, Program or Write cycle is in process (when BUSY equals
1) the instruction is ignored and will not have any effects on the current cycle.

W25Q128FV
8.2.30 Read SFDP Register (5Ah)
The W25Q128BV features a 256-Byte Serial Flash Discoverable Parameter (SFDP) register that contains
information about device configurations, available instructions and other features. The SFDP parameters
are stored in one or more Parameter Identification (PID) tables. Currently only one PID table is specified,
but more may be added in the future. The Read SFDP Register instruction is compatible with the SFDP
standard initially established in 2010 for PC and other applications, as well as the JEDEC standard
JESD216 that is published in 2011. Most Winbond SpiFlash Memories shipped after June 2011 (date
code 1124 and beyond) support the SFDP feature as specified in the applicable datasheet.
The Read SFDP instruction is initiated by driving the /CS pin low and shifting the instruction code “5Ah”
followed by a 24-bit address (A23-A0)(1) into the DI pin. Eight “dummy” clocks are also required before the
SFDP register contents are shifted out on the falling edge of the 40th CLK with most significant bit (MSB)
first as shown in Figure 34. For SFDP register values and descriptions, please refer to the Winbond
Application Note for SFDP Definition Table.
Note 1: A23-A8 = 0; A7-A0 are used to define the starting byte address for the 256-Byte SFDP Register.

W25Q128FV
8.2.31 Erase Security Registers (44h)
The W25Q128FV offers three 256-byte Security Registers which can be erased and programmed
individually. These registers may be used by the system manufacturers to store security and other
important information separately from the main memory array.
The Erase Security Register instruction is similar to the Sector Erase instruction. A Write Enable
instruction must be executed before the device will accept the Erase Security Register Instruction (Status
Register bit WEL must equal 1). The instruction is initiated by driving the /CS pin low and shifting the
instruction code “44h” followed by a 24-bit address (A23-A0) to erase one of the three security registers.

The Erase Security Register instruction sequence is shown in Figure 45. The /CS pin must be driven high
after the eighth bit of the last byte has been latched. If this is not done the instruction will not be executed.
After /CS is driven high, the self-timed Erase Security Register operation will commence for a time
duration of tSE (See AC Characteristics). While the Erase Security Register cycle is in progress, the Read
Status Register instruction may still be accessed for checking the status of the BUSY bit. The BUSY bit is
a 1 during the erase cycle and becomes a 0 when the cycle is finished and the device is ready to accept
other instructions again. After the Erase Security Register cycle has finished the Write Enable Latch
(WEL) bit in the Status Register is cleared to 0. The Security Register Lock Bits (LB3-1) in the Status
Register-2 can be used to OTP protect the security registers. Once a lock bit is set to 1, the corresponding
security register will be permanently locked, Erase Security Register instruction to that register will be
ignored (Refer to section 7.1.8 for detail descriptions).

8.2.32 Program Security Registers (42h)
The Program Security Register instruction is similar to the Page Program instruction. It allows from one
byte to 256 bytes of security register data to be programmed at previously erased (FFh) memory locations.
A Write Enable instruction must be executed before the device will accept the Program Security Register
Instruction (Status Register bit WEL= 1). The instruction is initiated by driving the /CS pin low then shifting
the instruction code “42h” followed by a 24-bit address (A23-A0) and at least one data byte, into the DI pin.
The /CS pin must be held low for the entire length of the instruction while data is being sent to the device.

8.2.33 Read Security Registers (48h)
The Read Security Register instruction is similar to the Fast Read instruction and allows one or more data
bytes to be sequentially read from one of the four security registers. The instruction is initiated by driving
the /CS pin low and then shifting the instruction code “48h” followed by a 24-bit address (A23-A0) and
eight “dummy” clocks into the DI pin. The code and address bits are latched on the rising edge of the CLK
pin. After the address is received, the data byte of the addressed memory location will be shifted out on
the DO pin at the falling edge of CLK with most significant bit (MSB) first. The byte address is
automatically incremented to the next byte address after each byte of data is shifted out. Once the byte
address reaches the last byte of the register (byte address FFh), it will reset to address 00h, the first byte
of the register, and continue to increment. The instruction is completed by driving /CS high. The Read
Security Register instruction sequence is shown in Figure 47. If a Read Security Register instruction is
issued while an Erase, Program or Write cycle is in process (BUSY=1) the instruction is ignored and will
not have any effects on the current cycle. The Read Security Register instruction allows clock rates from
D.C. to a maximum of FR (see AC Electrical Characteristics).

8.2.34 Set Read Parameters (C0h)
In QPI mode, to accommodate a wide range of applications with different needs for either maximum read
frequency or minimum data access latency, “Set Read Parameters (C0h)” instruction can be used to
configure the number of dummy clocks for “Fast Read (0Bh)”, “Fast Read Quad I/O (EBh)” & “Burst Read
with Wrap (0Ch)” instructions, and to configure the number of bytes of “Wrap Length” for the “Burst Read
with Wrap (0Ch)” instruction.
In Standard SPI mode, the “Set Read Parameters (C0h)” instruction is not accepted. The dummy clocks
for various Fast Read instructions in Standard/Dual/Quad SPI mode are fixed, please refer to the
Instruction Table 1-2 for details. The “Wrap Length” is set by W5-4 bit in the “Set Burst with Wrap (77h)”
instruction. This setting will remain unchanged when the device is switched from Standard SPI mode to
QPI mode.
The default “Wrap Length” after a power up or a Reset instruction is 8 bytes, the default number of
dummy clocks is 2. The number of dummy clocks is only programmable for “Fast Read (0Bh)”, “Fast
Read Quad I/O (EBh)” & “Burst Read with Wrap (0Ch)” instructions in the QPI mode. Whenever the
device is switched from SPI mode to QPI mode, the number of dummy clocks should be set again, prior to
any 0Bh, EBh or 0Ch instructions.

8.2.35 Burst Read with Wrap (0Ch)
The “Burst Read with Wrap (0Ch)” instruction provides an alternative way to perform the read operation
with “Wrap Around” in QPI mode. The instruction is similar to the “Fast Read (0Bh)” instruction in QPI
mode, except the addressing of the read operation will “Wrap Around” to the beginning boundary of the
“Wrap Length” once the ending boundary is reached.
The “Wrap Length” and the number of dummy clocks can be configured by the “Set Read Parameters
(C0h)” instruction.

8.2.36 Enter QPI Mode (38h)
The W25Q128FV support both Standard/Dual/Quad Serial Peripheral Interface (SPI) and Quad Peripheral
Interface (QPI). However, SPI mode and QPI mode cannot be used at the same time. “Enter QPI (38h)”
instruction is the only way to switch the device from SPI mode to QPI mode.
Upon power-up, the default state of the device upon is Standard/Dual/Quad SPI mode. This provides full
backward compatibility with earlier generations of Winbond serial flash memories. See Instruction Set
Table 1-3 for all supported SPI commands. In order to switch the device to QPI mode, the Quad Enable
(QE) bit in Status Register-2 must be set to 1 first, and an “Enter QPI (38h)” instruction must be issued. If
the Quad Enable (QE) bit is 0, the “Enter QPI (38h)” instruction will be ignored and the device will remain
in SPI mode.
See Instruction Set Table 3 for all the commands supported in QPI mode.
When the device is switched from SPI mode to QPI mode, the existing Write Enable and Program/Erase
Suspend status, and the Wrap Length setting will remain unchanged.

8.2.38 Individual Block/Sector Lock (36h)
The Individual Block/Sector Lock provides an alternative way to protect the memory array from adverse
Erase/Program. In order to use the Individual Block/Sector Locks, the WPS bit in Status Register-3 must
be set to 1. If WPS=0, the write protection will be determined by the combination of CMP, SEC, TB,
BP[2:0] bits in the Status Registers. The Individual Block/Sector Lock bits are volatile bits. The default
values after device power up or after a Reset are 1, so the entire memory array is being protected.
To lock a specific block or sector as illustrated in Figure 4d, an Individual Block/Sector Lock command
must be issued by driving /CS low, shifting the instruction code “36h” into the Data Input (DI) pin on the
rising edge of CLK, followed by a 24-bit address and then driving /CS high. A Write Enable instruction
must be executed before the device will accept the Individual Block/Sector Lock Instruction (Status
Register bit WEL= 1).

To unlock a specific block or sector as illustrated in Figure 4d, an Individual Block/Sector Unlock
command must be issued by driving /CS low, shifting the instruction code “39h” into the Data Input (DI) pin
on the rising edge of CLK, followed by a 24-bit address and then driving /CS high. A Write Enable
instruction must be executed before the device will accept the Individual Block/Sector Unlock Instruction
(Status Register bit WEL= 1).

8.2.40 Read Block/Sector Lock (3Dh)
The Individual Block/Sector Lock provides an alternative way to protect the memory array from adverse
Erase/Program. In order to use the Individual Block/Sector Locks, the WPS bit in Status Register-3 must
be set to 1. If WPS=0, the write protection will be determined by the combination of CMP, SEC, TB,
BP[2:0] bits in the Status Registers. The Individual Block/Sector Lock bits are volatile bits. The default
values after device power up or after a Reset are 1, so the entire memory array is being protected.
To read out the lock bit value of a specific block or sector as illustrated in Figure 4d, a Read Block/Sector
Lock command must be issued by driving /CS low, shifting the instruction code “3Dh” into the Data Input
(DI) pin on the rising edge of CLK, followed by a 24-bit address. The Block/Sector Lock bit value will be
shifted out on the DO pin at the falling edge of CLK with most significant bit (MSB) first as shown in Figure
54. If the least significant bit (LSB) is 1, the corresponding block/sector is locked; if LSB=0, the
corresponding block/sector is unlocked, Erase/Program operation can be performed.

8.2.41 Global Block/Sector Lock (7Eh)
All Block/Sector Lock bits can be set to 1 by the Global Block/Sector Lock instruction. The command must
be issued by driving /CS low, shifting the instruction code “7Eh” into the Data Input (DI) pin on the rising
edge of CLK, and then driving /CS high. A Write Enable instruction must be executed before the device
will accept the Global Block/Sector Lock Instruction (Status Register bit WEL= 1).

8.2.43 Enable Reset (66h) and Reset Device (99h)
Because of the small package and the limitation on the number of pins, the W25Q128FV provide a
software Reset instruction instead of a dedicated RESET pin. Once the Reset instruction is accepted, any
on-going internal operations will be terminated and the device will return to its default power-on state and
lose all the current volatile settings, such as Volatile Status Register bits, Write Enable Latch (WEL)
status, Program/Erase Suspend status, Read parameter setting (P7-P0), Continuous Read Mode bit
setting (M7-M0) and Wrap Bit setting (W6-W4).
“Enable Reset (66h)” and “Reset (99h)” instructions can be issued in either SPI mode or QPI mode. To
avoid accidental reset, both instructions must be issued in sequence. Any other commands other than
“Reset (99h)” after the “Enable Reset (66h)” command will disable the “Reset Enable” state. A new
sequence of “Enable Reset (66h)” and “Reset (99h)” is needed to reset the device. Once the Reset
command is accepted by the device, the device will take approximately tRST=30us to reset. During this
period, no command will be accepted.
Data corruption may happen if there is an on-going or suspended internal Erase or Program operation
when Reset command sequence is accepted by the device. It is recommended to check the BUSY bit and
the SUS bit in Status Register before issuing the Reset command sequence.

Notes:
1. Clock high + Clock low must be less than or equal to 1/fC.
2. Value guaranteed by design and/or characterization, not 100% tested in production.
3. Only applicable as a constraint for a Write Status Register instruction when SRP[1:0]=(0,1).
4. For multiple bytes after first byte within a page, tBPN = tBP1 + tBP2 * N (typical) and tBPN = tBP1 + tBP2 * N (max), where N =
number of bytes programmed.
5. It is possible to reset the device with shorter tRESET (as short as a few hundred ns), a 1us minimum is recommended to
ensure reliable operation.
6. Tested on sample basis and specified through design and characterization data. TA = 25° C, VCC = 3.0V, 25% driver
strength.
