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 [A23-A0]. 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.
