Read Identification (RDID)
The Read Identification (RDID) instruction allows the device identification data to be read as
explained here, with the data values shown in
sequence.
Any Read Identification (RDID) instruction performed 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 1-byte instruction code
for the instruction is shifted in.
After this the 20-bytes stored in memory are shifted out on Serial Data output (Q), including
the 3-bytes of manufacturer and device identification information, the 1-byte CFD length,
and the 16 bytes of CFD content. Each bit of these 20-bytes is shifted out during the falling
edge of Serial Clock (C). The instruction sequence is shown in Figure 8: Read Identification
(RDID) instruction sequence and data-out sequence.
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
Stand-by Power mode. Once in the Stand-by Power mode, the device waits to be selected,
so that it can receive, decode and execute instructions.
Read Identification (RDID) data-out sequence
a. UID available on T9HX process technology parts.
Manufacturer identification (1 byte): Numonyx value assigned by JEDEC.
Device identification (2 bytes): assigned by the device manufacturer.
–
–
Unique ID code (UID) (17 bytes): available upon customer request.
–
–
The first byte indicates the memory type.
The second byte indicates the memory capacity of the device.
The first byte contains the length of the data that is contained in the UID.
The remaining 16 bytes are available upon customer request and contain the
optional Customized Factory Data (CFD) content. The CFD bytes are read-only
and can be programmed with customer data upon customer demand. If a
customer does not make a request, the device is shipped with all CFD bytes
programmed to zero (00h).
