Block Protection (BP2, BP1, BP0)
Block Protection Lock-Down (BPL)
The Block-Protection (BP2, BP1, BP0) bits define the size of the
memory area, as defined in Table2 to be software protected
against any memory Write (Program or Erase) operations. The
Write-Status-Register (WRSR) instruction is used to program the
WP pin driven low (VIL), enables the Block-Protection
-Lock-Down (BPL) bit. When BPL is set to 1, it prevents any
further alteration of the BPL, BP2, BP1, and BP0 bits. When the
WP pin is driven high (VIH), the BPL bit has no effect and its
value is “Don’t Care”. After power-up, the BPL bit is reset to 0.
BP2, P1, BP0 bits as long as WP is high or the
Block-Protection-Look (BPL) bit is 0. Chip-Erase can only be
executed if Block-Protection bits are all 0. After power-up, BP2,
BP1 and BP0 are set to1.

HOLD pin is used to pause a serial sequence underway with the

F25L016A provides software Write protection.
The Write Protect pin ( WP ) enables or disables the lockdown
function of the status register. The Block-Protection bits (BP1,
BP0, and BPL) in the status register provide Write protection to
the memory array and the status register. See Table 5 for
Block-Protection description.

the execution of the Write-Status-Register (WRSR) instruction is
determined by the value of the BPL bit (see Table 3). When WP

Status Register
The software status register provides status on whether the flash
memory array is available for any Read or Write operation,
whether the device is Write enabled, and the state of the memory
Write protection. During an internal Erase or Program operation,
the status register may be read only to determine the completion
of an operation in progress.

Busy
The Busy bit determines whether there is an internal Erase or
Program operation in progress. A “1” for the Busy bit indicates
the device is busy with an operation in progress. A “0” indicates
the device is ready for the next valid operation.
Write Enable Latch (WEL)
The Write-Enable-Latch bit indicates the status of the internal
memory Write Enable Latch. If the Write-Enable-Latch bit is set to
“1”, it indicates the device is Write enabled. If the bit is set to “0”
(reset), it indicates the device is not Write enabled and does not
accept any memory Write (Program/ Erase) commands. The
Write-Enable-Latch bit is automatically reset under the following
conditions:
• Power-up
• Write-Disable (WRDI) instruction completion
• Byte-Program instruction completion
• Auto Address Increment (AAI) programming is completed
or reached its highest unprotected memory address
• Sector-Erase instruction completion
• Block-Erase instruction completion
• Chip-Erase instruction completion

Instructions
Instructions are used to Read, Write (Erase and Program), and
configure the F25L016A. The instruction bus cycles are 8 bits
each for commands (Op Code), data, and addresses. Prior to
executing any Byte-Program, Sector-Erase, Block-Erase, or
Chip-Erase instructions, the Write-Enable (WREN) instruction
must be executed first. The complete list of the instructions is
provided in Table 5. All instructions are synchronized off a high to
low before an instruction is entered and must be driven high after
the last bit of the instruction has been shifted in (except for Read,
Read-ID and Read-Status-Register instructions). Any low to high
transition on CE , before receiving the last bit of an instruction
bus cycle, will terminate the instruction in progress and return the
device to the standby mode.
Instruction commands (Op Code), addresses, and data are all
input from the most significant bit (MSB) first.

of SCK starting with the most significant bit. CE must be driven

Read (33 MHz)
The Read instruction supports up to 33 MHz, it outputs the data
starting from the specified address location. The data output
stream is continuous through all addresses until terminated by a

the data from address location 1FFFFFH had been read, the next
output will be from address location 00000H.
The Read instruction is initiated by executing an 8-bit command,
low to high transition on CE . The internal address pointer will
automatically increment until the highest memory address is
reached. Once the highest memory address is reached, the
address pointer will automatically increment to the beginning
03H, followed by address bits [A23-A0]. CE must remain active
low for the duration of the Read cycle. See Figure 2 for the Read

Auto Address Increment (AAI) WORD Program
The AAI program instruction allows multiple bytes of data to be programmed without re-issuing the next sequential address location.
This feature decreases total programming time when the multiple bytes or entire memory array is to be programmed. An AAI program
instruction pointing to a protected memory area will be ignored. The selected address range must be in the erased state (FFH) when
initiating an AAI program instruction. While within AAI WORD programming sequence, the only valid instructions are AAI WORD
program operation, RDSR, WRDI. Users have three options to determine the completion of each AAI WORD program cycle: hardware
detection by reading the SO; software detection by polling the BUSY in the software status register or wait TBP. Refer to End-of-Write
Detection section for details.
Prior to any write operation, the Write-Enable (WREN) instruction must be executed. The AAI WORD program instruction is initiated by
executing an 8-bit command, ADH, followed by address bits [A23-A0]. Following the addresses, two bytes of data is input sequentially.
The data is input sequentially from MSB (bit 7) to LSB (bit 0). The first byte of data(DO) will be programmed into the initial address
[A23-A1] with A0 =0; The second byte of data(D1) will be programmed into the initial address [A23-A1] with A0 =1. CE must be driven
high before the AAI WORD program instruction is executed. The user must check the BUSY status before entering the next valid
command. Once the device indicates it is no longer busy, data for next two sequential addresses may be programmed and so on. When
the last desired byte had been entered, check the busy status using the hardware method or the RDSR instruction and execute the
WRDI instruction, to terminate AAI. User must check busy status after WRDI to determine if the device is ready for any command.
Please refer to Figures 7 and Figures 8.
There is no wrap mode during AAI programming; once the highest unprotected memory address is reached, the device will exit AAI
operation and reset the Write-Enable-Latch bit (WEL = 0) and the AAI bit (AAI=0).
End of Write Detection
There are three methods to determine completion of a program cycle during AAI WORD programming: hardware detection by reading
the SO, software detection by polling the BUSY bit in the Software Status Register or wait TBP. The hardware end of write detection
method is described in the section below.
Hardware End of Write Detection
The hardware end of write detection method eliminates the overhead of polling the BUSY bit in the software status register during an AAI
Word PROGRAM OPERATION. The 8bit command, 70H, configures the SO to indicate Flash Busy status during AAI WORD
programming (refer to figure5). The 8bit command, 70H, must be executed prior to executing an AAI WORD program instruction. Once
an internal programming operation begins, asserting CE will immediately drive the status of the internal flash status on the SO pin. A “0”
Indicates the device is busy ; a “1” Indicates the device is ready for the next instruction. De-asserting CE will return the SO pin to
tri-state. The 8bit command, 80H,disables the SO pin to output busy status during AAI WORD program operation and return SO pin to
output software register data during AAI WORD programming (refer to figure6).

JEDEC Read-ID
The JEDEC Read-ID instruction identifies the device as F25L016A and the manufacturer as ESMT. The device information can be read
from executing the 8-bit command,.9FH. Following the JEDEC Read-ID instruction, the 8-bit manufacturer’s ID, 8CH, is output from the
device. After that, a 16-bit device ID is shifted out on the SO pin. Byte1, BFH, identifies the manufacturer as ESMT. Byte2, 20H (for TOP),
21H (for BOTTOM),identifies the memory type as SPI Flash. Byte3, 15H, identifies the device as F25L016A. The instruction sequence is
shown in Figure16.
The JEDEC Read ID instruction is terminated by a low to high transition on CE at any time during data output. If no other command is
issued after executing the JEDEC Read-ID instruction, issue a 00H (NOP) command before going into Standby Mode ( CE =VIH).

Read-ID (RDID)
The Read-ID instruction (RDID) identifies the devices as F25L016A and manufacturer as ESMT. This command is backward compatible
to all ESMT SPI devices and should be used as default device identification when multiple versions of ESMT SPI devices are used in
one design. The device information can be read from executing an 8-bit command, 90H or ABH, followed by address bits [A23-A0].
Following the Read-ID instruction, the manufacturer’s ID is located in address 00000H and the device ID is located in address 00001H.
Once the device is in Read-ID mode, the manufacturer’s and device ID output data toggles between address 00000H and 00001H until
terminated by a low to high transition on CE .
