Device identification
9.1
Unique ID
The STLUX385A provides a 56-bits unique identifier code usable as device identification
number which can be used to increase the device security. The unique ID code is a frozen
signature not alterable by user.
The unique device identifier is ideally used by the application software and is suited for:
•
serial code
•
security keys in conjunction with cryptographic software to increase the embedded
flash code security
•
activating the secure boot sequence
9.2
Device ID
The STLUX385A device identification model is coded in the following register area and it
cannot be altered by the user.
The register fields have the follow meaning:
Dev_ID [7:0]:
Device identification model
0x00: STLUX385
Others: RFU reserved values
Rev_ID [4:0]:
Revision identification model
00000: STLUX385
00001: STLUX385A
Others: RFU reserved values
