Read Identification (RDID)
The Read Identification (RDID) instruction allows to read the device identification data:
Manufacturer identification (one byte)
Device identification (two bytes)
A Unique ID code (UID) followed by 16 bytes of CFI data
●
●
●
The manufacturer identification is assigned by JEDEC, and has the value 20h for
STMicroelectronics. The device identification is assigned by the device manufacturer, and
indicates the memory type in the first byte (71h), and the memory capacity of the device in
the second byte (16h). The UID is set to 10h and indicates that 16 bytes, related to the CFI
content, are following.
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 Read Identification (RDID) instruction should not be issued while the device is in Deep
Power-down mode.
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, the 8-bit Unique ID code followed by 16 bytes of CFI content 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
Figure 10
.
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.
