Read identification (RDID)
The read identification (RDID) instruction allows to read the device identification data:
The manufacturer identification is assigned by JEDEC, and has the value 20h for Numonyx.
Any read identification (RDID) instruction while an erase or program cycle is in progress, is
not decoded, and has no effect on the cycle that is in progress.
The device is first selected by driving Chip Select (S) Low. Then, the 8-bit instruction code
for the instruction is shifted in. After this, the 24-bit device identification stored in the memory
will be shifted out on serial data output (DQ1). Each bit is shifted out during the falling edge
of Serial Clock (C).
The instruction sequence is shown in
The read identification (RDID) instruction is terminated by driving Chip Select (S) High at
any time during data output.
When Chip Select (S) is driven High, the device is put in the standby power mode. Once in
the standby power mode, the device waits to be selected, so that it can receive, decode and
execute instructions.
