9.2.14 JEDEC ID (9Fh)
For compatibility reasons, the W25P80/16/32 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 17. For the W25P80, the Memory Type is 20h and the Capacity is
14h. For the W25P16, the Memory type is also 20h and the Capacity is 15h. For the W25P32, the
Memory type is also 20h and the Capacity is 16h.
