Read Manufacture ID/ Device ID Dual I/O (92H)

The Read Manufacturer/Device ID Dual I/O 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

by dual I/O.

The command is initiated by driving the CS# pin low and shifting the command code “92H” 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 Figure 23 If the 24-bit address

is initially set to 000001H, the Device ID will be read first.

Read Manufacture ID/ Device ID Quad I/O (94H)

The Read Manufacturer/Device ID Quad I/O 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

by quad I/O. The command is initiated by driving the CS# pin low and shifting the command code “94H”

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 is shown in Figure 25. If the

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