SST25VF016B

4.4.16 READ-ID (RDID)

The Read-ID instruction (RDID) identifies the devices

as SST25VF016B and manufacturer as Microchip. This

command is backward compatible to all SST25xFxxxA

devices and should be used as default device identifi-

cation 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 [A23-A0]. Following the

FIGURE 4-19:

READ-ID SEQUENCE

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 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 4-5 and 4-6 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.
