JEDEC Read-ID

The JEDEC Read-ID instruction identifies the device as

SST25WF512/010/020/040 and the manufacturer as SST.

The device information can be read from executing the 8-

bit command, 9FH. Following the JEDEC Read-ID instruc-

tion, 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. The Device ID is assigned by the manufacturer and

contains the type of memory in the first byte and the mem-

ory capacity of the device in the second byte. See Figure

23 for the instruction sequence. The JEDEC Read ID

instruction is terminated by a low to high transition on CE#

at any time during data output.
