F25L32QA
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, 40H, identifies the
memory type as SPI Flash. Byte3, 16H, identifies the device as
F25L32QA. The instruction sequence is shown in Figure 28.
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).
