W25Q80DV
Read Manufacturer / Device ID Quad I/O (94h)
The Read Manufacturer / Device ID Quad 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 4x speed.
The Read Manufacturer / Device ID Quad I/O instruction is 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,but with the capability to input the Address bits four bits per clock.
After which, the Manufacturer ID for Winbond (EFh) and the Device ID are shifted out four bits per clock
on the falling edge of CLK with most significant bit (MSB) first as shown in figure 31. The Device ID
values for the W25Q80DV is 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 Quad I/O instruction.
