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 Figure22. If
the 24-bit address is initially set to 000001H, the Device ID will be read first.
