4.4.15 JEDEC READ-ID

The JEDEC Read-ID instruction identifies the device as

SST25VF016B and the manufacturer as Microchip.

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 manufac-

turer as Microchip. Byte 2, 25H, identifies the memory

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

device as SST25VF016B. The instruction sequence is

shown in Figure 4-18. 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).
