SST25VF016B

JEDEC Read-ID

The JEDEC Read-ID instruction identifies the device as

SST25VF016B and the manufacturer as SST. The device

information can be read from executing the 8-bit command,

9FH. Following the JEDEC Read-ID instruction, the 8-bit

manufacturer’s ID, BFH, is output from the device. After

that, a 16-bit device ID is shifted out on the SO pin. Byte 1,

BFH, identifies the manufacturer as SST. Byte 2, 25H, iden-

tifies the memory type as SPI Serial Flash. Byte 3, 41H,

identifies the device as SST25VF016B. The instruction

Data Sheet

sequence is shown in Figure 20. The JEDEC Read ID

instruction is terminated by a low to high transition on CE#

at any time during data output. If no other command is

issued after executing the JEDEC Read-ID instruction,

issue a 00H (NOP) command before going into Standby

Mode (CE#=VIH).
