• Manufacturer: SST [Silicon Storage Technology, Inc]

Data Sheet
Read-ID (RDID)
The Read-ID instruction (RDID) identifies the devices as
SST25VF080B and manufacturer as SST. This command
is backward compatible and should be used as default
device identification when multiple versions of SPI Serial
Flash devices are used in a design. The device information
can be read from executing an 8-bit command, 90H or
ABH, followed by address bits [A
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
high transition on CE#.
