GENERAL DESCRIPTION
The F25L32QA is a 32Megabit, 3V only CMOS Serial Flash
memory device. The device supports the standard Serial
Peripheral Interface (SPI), and a Dual/Quad SPI. ESMT’s
memory devices reliably store memory data even after 100,000
programming and erase cycles.
The memory array can be organized into 16,384 programmable
pages of 256 byte each. 1 to 256 byte can be programmed at a
time with the Page Program instruction.
The device features sector erase architecture. The memory array

is divided into 1,024 uniform sectors with 4K byte each; 128
uniform blocks with 32K byte each; 64 uniform blocks with 64K
byte each. Sectors can be erased individually without affecting
the data in other sectors. Blocks can be erased individually
without affecting the data in other blocks. Whole chip erase
capabilities provide the flexibility to revise the data in the device.
The device has Sector, Block or Chip Erase but no page erase.
The sector protect/unprotect feature disables both program and
erase operations in any combination of the sectors of the
memory.

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. Table 2 describes the function of
each bit in the software status register.

The Write-Enable-Latch bit indicates the status of the internal
memory Write Enable Latch. If this 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. This bit is automatically reset
under the following conditions:
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.

Block Protection (BP3, BP2, BP1, BP0)
The Block-Protection (BP3, BP2, BP1, BP0) bits define the
memory area, as defined in Table 3, 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-ProtectionLock-Down (BPL) bit. When BPL is set to 1, it prevents any
further alteration of the BPL, BP3, 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”.
BP3, BP2, BP1 and BP0 bits as long as WP is high or the
Block- Protection-Look (BPL) bit is 0. Chip Erase can only be
executed if BP3, BP2, BP1 and BP0 bits are all 0. The factory
default setting for Block Protection Bit (BP3 ~ BP0) is 0.
Block Protection Lock-Down (BPL)
Quad Enable (QE)
Program / Erase Suspend Status (SUS)
When the Quad Enable bit is reset to “0” (factory default), WP
The Suspend Status bit is a read only bit in the status register

HOLD OPERATION
HOLD pin is used to pause a serial sequence underway with the
SPI flash memory without resetting the clocking sequence. To
activate the HOLD mode, CE must be in active low state. The
Once the device enters Hold mode, SO will be in high impedance
state while SI and SCK can be VIL or VIH.
HOLD mode begins when the SCK active low state coincides
If CE is driven active high during a Hold condition, it resets the
with the falling edge of the HOLD signal. The HOLD mode ends
internal logic of the device. As long as HOLD signal is low, the
memory remains in the Hold condition. To resume
when the HOLD signal’s rising edge coincides with the SCK
active low state.
If the falling edge of the HOLD signal does not coincide with the
SCK active low state, then the device enters Hold mode when the
SCK next reaches the active low state.
Similarly, if the rising edge of the HOLD signal does not
coincide with the SCK active low state, then the device exits in
Hold mode when the SCK next reaches the active low state. See
Figure 1 for Hold Condition waveform.
communication with the device, HOLD must be driven active
high, and CE must be driven active low. See Figure 35 for Hold
timing.
The HOLD function is only available for Standard SPI and Dual
SPI operation, not during Quad SPI because this pin is used for
SIO3 when the QE bit of Status Register-1 is set for Quad I/O.

WRITE PROTECTION
The device provides software Write Protection.
The Write-Protect pin ( WP ) enables or disables the lock-down
function of the status register. The Block-Protection bits (BP3,
BP2, BP1, BP0 and BPL) in the status register provide Write
protection to the memory array and the status register. When the
QE bit of Status Register-1 is set for Quad I/O, the WP pin
function is not available since this pin is used for SIO2.

Write Protect Pin ( WP )
The Write-Protect ( WP ) pin enables the lock-down function of
the BPL bit (bit 7) in the status register. When WP is driven low,
the execution of the Write Status Register (WRSR) instruction is
determined by the value of the BPL bit (see Table 4). When WP
is high, the lock-down function of the BPL bit is disabled.

INSTRUCTIONS
Instructions are used to Read, Write (Erase and Program), and
configure the F25L32QA. The instruction bus cycles are 8 bits
each for commands (Op Code), data, and addresses. Prior to
executing any Page Program, Write Status Register, 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
entered and must be driven high after the last bit of the instruction
has been shifted in (except for Read, Read ID, Read Status
Register, Read Electronic Signature instructions). Any low to high

If [M7 –M0] = “AxH”, the next Fast Read Quad I/O instruction (after
CE is raised and the lowered) doesn’t need the command code

reset mode bits [M7 –M0] before issuing normal instructions.
To set mode bits [M7 -M0] after the address bits [A23 -A0] can

Mode Bit Reset
Mode bits [M7 –M0] are issued to further reduce instruction
overhead for Fast Read Dual/Quad I/O operation. If [M7 –M0] =
“AxH”, the next Fast Read Dual/Quad I/O instruction doesn’t
need the command code.
However, the device doesn’t have a hardware reset pin, so if
[M7 –M0] = “AxH”, the device will not recognize any standard SPI
instruction. After a system reset, it is recommended to issue a
Mode Bit Reset instruction first to release the status of [M7 –M0] =
“AxH” and allow the device to recognize standard SPI instruction.
See Figure 12 for the Mode Bit Reset instruction.
If the system controller is reset during operation, it will send a
standard instruction (such as Read ID) to the Flash memory.

JEDEC Read-ID
The JEDEC Read-ID instruction identifies the device as
F25L32QA 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, 8CH,
identifies the manufacturer as ESMT. Byte2, 41H, identifies the
memory type as SPI Flash. Byte3, 16H, identifies the device as
F25L32QA. The instruction sequence is shown in Figure 27.
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).
