Data Sheet
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 23 -A 0 ]. Following 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 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.

Note: The manufacturer s and device ID output stream is continuous until terminated by a low to high transition on CE#.
1. 00H will output the manfacturer s ID first and 01H will output device ID first before toggling between the two.
