ESMT
Read-ID (RDID)
The Read-ID instruction (RDID) identifies the devices as F25L004A and manufacturer as ESMT. This command is backward compatible
to all ESMT SPI devices and should be used as default device identification when multiple versions of ESMT SPI devices are used in
one design. The device information can be read from executing an 8-bit command, 90H or ABH, followed by address bits [A
Following the Read-ID instruction, the manufacturer’s ID is located in address 00000H and the device ID is located in address 00001H.
Once the device is in Read-ID mode, the manufacturer’s and device ID output data toggles between address 00000H and 00001H until
terminated by a low to high transition on CE .
