Read Manufacturer / Device ID Dual I/O (92h)

The Read Manufacturer/ Device ID Dual I/O instruction provides both the JEDEC assigned manufacturer ID and the

specific device ID.

The Read Manufacturer/ Device ID instruction is very similar to the Fast Read Dual I/O instruction. The instruction is

initiated by driving the CS pin low and shifting the instruction code “92h” followed by a 24-bit address (A23-A0) of

000000h. After which, the Manufacturer ID for Adesto (1Fh) and the Device ID (17h) are shifted out on the falling edge of

SCK with most significant bit (MSB) first as shown in Figure 7-44. If the 24-bit address is initially set to 000001h the

Device ID is read first and then followed by the Manufacturer ID. The Manufacturer and Device ID can be read

continuously, alternating from one to the other. The instruction is completed by driving CS high.

Read Manufacturer / Device ID Quad I/O (94h)

The Read Manufacturer/ Device ID Quad I/O instruction provides both the JEDEC assigned manufacturer ID and the

specific device ID.

The Read Manufacturer/ Device ID instruction is very similar to the Fast Read Quad I/O instruction. The instruction is

initiated by driving the CS pin low and shifting the instruction code “94h” followed by a 24-bit address (A23-A0) of

000000h. After which, the Manufacturer ID for Adesto (1Fh) and the Device ID (17h) are shifted out on the falling edge of

SCK with most significant bit (MSB) first as shown in Figure 7-45. If the 24-bit address is initially set to 000001h the

Device ID is read first and then followed by the Manufacturer ID. The Manufacturer and Device ID can be read

continuously, alternating from one to the other. The instruction is completed by driving CS high.
