7.22 Read Manufacture Id/ Device Id (REMS) (90H)

The Read Manufacturer/Device ID command is an alternative to the Release from Power-Down / Device ID command that

provides both the JEDEC assigned Manufacturer ID and the specific Device ID.

The command is initiated by driving the CS# pin low and shifting the command code “90H” followed by a 24-bit address

(A23-A0) of 000000H. After which, the Manufacturer ID and the Device ID are shifted out on the falling edge of SCLK with

most significant bit (MSB) first as shown in Figure24. If the 24-bit address is initially set to 000001H, the Device ID will be

read first.
