EN25P80

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 Eon (1Ch) and the

Device ID are shifted out on the falling edge of CLK with most significant bit (MSB) first as shown in

Figure 17. The Device ID values for the EN25P80 are listed in Table 5. If the 24-bit address is initially set

to 000001h the Device ID will be read first
