Read Manufacturer / Device ID Dual I/O (92h)
The Read 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 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
S25FL016K is listed in
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:
1. The “Continuous Read Mode” bits M(7-0) must be set to Fxh to be compatible with Fast Read Dual I/O instruction.
