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
and the device ID is located in address 00001H. Once the device is in Read-ID mode, the manufac-
turer’s and device ID output data toggles between address 00000H and 00001H until terminated by a
low to high transition on CE#.
Refer to Tables 6 and 7 for device identification data.
