JEDEC ID (9Fh)

For compatibility reasons, the AT25QL641 provides several instructions to electronically determine the identity of the

device. The Read JEDEC ID instruction is compliant with the JEDEC standard for SPI compatible serial Flash memories

that was adopted in 2003. The instruction is entered by driving the CS pin low with following the instruction code “9Fh”.

JEDEC assigned Manufacturer ID byte for Adesto (1Fh) and two Device ID bytes, Memory Type (ID15-ID8) and

Capacity (ID7-ID0) are then shifted out on the falling edge of SCK with most significant bit (MSB) first shown in Figure

7-46 and Figure 7-47. For memory type and capacity values refer to Manufacturer and Device Identification table. The

JEDEC ID can be read continuously. The instruction is terminated by driving CS high.
