W25Q80DV
Read Manufacturer / Device ID Dual I/O (92h)
The Manufacturer / Device ID Dual I/O instruction is an alternative to the Read Manufacturer/Device ID
instruction that provides both the JEDEC assigned manufacturer ID and the specific device ID at 2x
speed.
The Read Manufacturer / Device ID Dual I/O instruction is 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, but with the capability to input the Address bits two bits per clock.
After which, the Manufacturer ID for Winbond (EFh) and the Device ID are shifted out 2 bits per clock
on the falling edge of CLK with most significant bits (MSB) first as shown in figure 30. The Device ID
values for the W25Q80DV are listed in Manufacturer and Device Identification table. The Manufacturer
and Device IDs can be read continuously, alternating from one to the other. The instruction is completed
by driving /CS high.

Note:
1. The “Continuous Read Mode” bits M7-0 must be set to FFh to be compatible with Fast Read Dual I/O instruction.
