W25Q16DW
7.2.32
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
four clock dummy cycles and then 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 W25Q16DW is listed in Manufacturer and Device Identification
table. If the 24-bit address is initially set to 000001h the Device ID will be read first and then followed by
the Manufacturer ID. The Manufacturer and Device IDs can be read continuously, alternating from one to
the other. The instruction is completed by driving /CS high.
