Read-ID (RDID)
The Read-ID instruction (RDID) identifies the device as
SST25VF032B and manufacturer as SST. The device
information can be read from executing an 8-bit command,
90H or ABH, followed by address bits [A
the Read-ID instruction, the manufacturer’s ID is located in
address 00000H and the device ID is located in address

00001H. Once the device is in Read-ID mode, the manu-
facturer’s and device ID output data toggles between
address 00000H and 00001H until terminated by a low to
