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 multi-
ple 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
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 manufacturer’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.
