JEDEC Read-ID
The JEDEC Read-ID instruction identifies the device as SST25VF080B 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 16-bit
device ID is shifted out on the SO pin. Byte 1, BFH, identifies the manufacturer as SST. Byte 2, 25H,
identifies the memory type as SPI Serial Flash. Byte 3, 8EH, identifies the device as SST25VF080B.
The instruction sequence is shown in Figure 20. The JEDEC Read ID instruction is terminated by a low
to high transition on CE# at any time during data output.
