Read-ID (RDID)
The Read-ID instruction (RDID) identifies the devices as SST25VF016B and manufacturer as SST.
This command is backward compatible to all SST25xFxxxA devices 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
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.
