The Cortex M3 have the “ID Unique device ID register (96 bits) “, this number give to the user application technical information about the Cortex M3 mounted in the PCB ?.
Extract from the datasheet RM008 revision 14
The unique device identifier is ideally suited:
● for use as serial numbers (for example USB string serial numbers or other end
● for use as security keys in order to increase the security of code in Flash memory while
using and combining this unique ID with software cryptographic primitives and
protocols before programming the internal Flash memory
● to activate secure boot processes, etc.
The 96-bit unique device identifier provides a reference number which is unique for any
device and in any context. These bits can never be altered by the user.
The 96-bit unique device identifier can also be read in single bytes/half-words/words in
different ways and then be concatenated using a custom algorithm.
Base address: 0x1FFF F7E8
It’s possible to know more information about this number ? ST give this information ? For our application we would like to know more information about the Cortex M3 in run time.
