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, 8-bit Continuous Read Mode Bits, 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 28. The Device ID values for the W25X05CL/10CL/20CL are 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.

Note:

“Continuous Read Mode” bits M7-0 must be set to FXh to be compatible with Fast Read Dual I/O instruction.
