ESMT
JEDEC Read-ID
The JEDEC Read-ID instruction identifies the device as F25L008A 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,
identifies the memory type as SPI Flash. Byte3, 14H, identifies the device as F25L008A. The instruction sequence is shown in Figure13.
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 =V
