Revision B

8.2.21 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 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 for Winbond

(EFh) and the Device ID are shifted out on the falling edge of CLK with most significant bit (MSB) first

as shown in figure 22. The Device ID values for the W25X05CL/10CL/20CL are listed in Manufacturer

and Device Identification table. 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 instruction is completed by driving /CS high.
