ESMT
Read-ID (RDID)
The Read-ID instruction (RDID) identifies the devices as
F25L32QA 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,
followed by address bits [A

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 .
