W25Q80DV
Read JEDEC ID (9Fh)
For compatibility reasons, the W25Q80DV provide 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 33a. For memory type and capacity values refer to Manufacturer and Device
Identification table.
