7.5.3 Read Manufacturer / Device ID (90h)

The Read Manufacturer/Device ID instruction is an alternative to the Release from Power-down/Device

ID instruction that provides both the JEDEC assigned manufacturer ID and the specific device ID.

The Read Manufacturer/Device ID instruction is very similar to the Release from Power-down / Device ID

instruction. The instruction is initiated by driving the CS# pin low and shifting the instruction 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 CLK with most significant bit (MSB) first as shown in Figure 7.30. If the 24-bit

address is initially set to 000001h the Device ID will be read first and then followed by the Manufacturer ID.

The Manufacturer and Device IDs can be read continuously, alternating from one to the other. The command

is completed by driving CS# high.
