EN25B05
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 EN25B05 are listed in Table 5. If the 24-bit address is initially set
to 000001h the Device ID will be read first
