Preliminary - Revision A

11.2.35 Read JEDEC ID (9Fh)

For compatibility reasons, the W25Q16CL 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 33. For memory type and

capacity values refer to Manufacturer and Device Identification table.
