6.2.31 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 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 29. The Device ID values for the W25Q16CL is listed in Manufacturer and Device Identification
table. IDs can be read continuously, alternating from one to the other. The instruction is completed by
driving /CS high.
