12.2.17 JEDEC ID (9Fh)
For compatibility reasons, the W25X16/16A/32/64 provides several instructions to electronically
determine the identity of the device. The Read JEDEC ID instruction is compatible with the JEDEC
standard for SPI compatible serial memories that was adopted in 2003.
The instruction is initiated by driving the /CS pin low and shifting the instruction code “9Fh”. The
JEDEC assigned Manufacturer ID byte for Winbond (EFh) and two Device ID bytes, Memory Type
(ID15-ID8) and Capacity (ID7-ID0) are then shifted out on the falling edge of CLK with most significant
bit (MSB) first as shown in figure 19. For memory type and capacity values refer to Manufacturer and
Device Identification table.
