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.

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")  
4.6Reset (/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.

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.  
Publication Release Date: May 13, 2016  
- 12 -  
Revision M  
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.  
- 13 -  
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:  
1. 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.  
2. There is an internal pull-up resistor for the dedicated /RESET pin on the SOIC-16 package. If the reset function is not needed,  
this pin can be left floating in the system.

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.

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.

7.1.1 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  
Publication Release Date: May 13, 2016  
- 16 -  
Revision M  
W25Q128FV  
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.  
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.

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.  
7.1.10Quad 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 for part number with ordering  
options IG,IPand IF), the /WP pin and /HOLD are enabled. When the QE bit is set to a 1(factory  
default for Quad Enabled part numbers with ordering option IQ), 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.

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.

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.  
3.  
The Status Register contents and Device ID will repeat continuously until /CS terminates the instruction.  
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.  
4.  
5.  
Write Status Register-1 (01h) can also be used to program Status Register-1&2, see section 8.2.5.

8.2Instruction 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.

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.  
- 31 -  
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.

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.

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.

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.

8.2.13Octal 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.

8.2.14Set 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 Read Quad I/O” instructions will use the W6-4 setting to access the 8/16/32/64-byte section  
within any 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.

8.2.15Page 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.

8.2.16Quad 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.

8.2.17Sector 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.

8.2.20Chip 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

8.2.21Erase / 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 that was being suspended may become corrupted. It is recommended for the user to implement  
system design techniques against the accidental power interruption and preserve data integrity during  
erase/program suspend state.

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.

8.2.23Power-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.

8.2.24Release 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.

8.2.25 Read Manufacturer / Device ID (90h)  
The Read Manufacturer/Device ID instruction is an alternative to the Release from Power-down / Device  
ID instruction that provides both the JEDEC assigned manufacturer ID and the specific device ID.  
The Read Manufacturer/Device ID instruction is very similar to the Release from Power-down / Device  
ID instruction. The instruction is initiated by driving the /CS pin low and shifting the instruction code  
“90h” followed by a 24-bit address (A23-A0) of 000000h. After which, the Manufacturer ID for Winbond  
(EFh) and the Device ID are shifted out on the falling edge of CLK with most significant bit (MSB) first as  
shown in Figure 39. The Device ID values for the W25Q128FV are listed in Manufacturer and Device  
Identification table. The instruction is completed by driving /CS high.

For compatibility reasons, the W25Q128FV provides several instructions to electronically determine the  
identity of the device. The Read JEDEC ID instruction is compatible with the JEDEC standard for SPI  
compatible serial memories that was adopted in 2003. The instruction is initiated by driving the /CS pin  
low and shifting the instruction code “9Fh”. The JEDEC assigned Manufacturer ID byte for Winbond  
(EFh) and two Device ID bytes, Memory Type (ID15-ID8) and Capacity (ID7-ID0) are then shifted out on  
the falling edge of CLK with most significant bit (MSB) first as shown in Figure 43a & 43b. For memory  
type and capacity values refer to Manufacturer and Device Identification table.

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.

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.

Don’t Care  
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).

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.

8.2.33Read 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).

W25Q128FV  
8.2.34Set 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.

8.2.35Burst 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.

8.2.36Enter 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.

In order to exit the QPI mode and return to the Standard/Dual/Quad SPI mode, an “Exit QPI (FFh)”  
instruction must be issued.  
When the device is switched from QPI mode to SPI mode, the existing Write Enable Latch (WEL) and

8.2.38Individual 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).

8.2.39Individual Block/Sector Unlock (39h)  
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 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).

8.2.40Read 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.

8.2.43  
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.Its possible to reset the device with shorter tRESET (as short as a few hundred ns), a 1us minimum is recommended to ensure  
reliable operation.
