10.2.16 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 18. The Device ID values for the W25X10AL, W25X20AL, W25X40AL and
W25X80AL 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.
