Data Sheet
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 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#.
Device ID = 41H for SST25VF016B
1. 00H will output the manfacturer s ID first and 01H will output device ID first before toggling between the two.
