Read Manufacturer / Device ID (90h)
The Read Manufacturer/Device ID instruction is an alternative to the Release from Power -down /
Device ID instruction that provides both the JEDEC assigned manufacturer ID and the specific device
ID.
The Read Manufacturer/Device ID instruction is very similar to the Release from Power -down /
Device ID instruction. The instruction is initiated by driving the CS# pin low and shifting the instruction
code “90h” followed by a 24-bit address A23-A0 of 000000h. After which, the Manufacturer ID for ACE
Technology CO., LTD. (A1h) and the Device ID are shifted out on the falling edge of CLK with most
significant bit (MSB) first as shown in Figure 21. The Device ID value for the ACE25C200 is listed in
Table 3 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.
