SST25VF032B
JEDEC Read-ID
The JEDEC Read-ID instruction identifies the device as
SST25VF032B and the manufacturer as SST. 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, BFH, is output from the device. After
that, a 24-bit device ID is shifted out on the SO pin. Byte 1,
