Unique ID

STM8TL5xx4 devices feature a 96-bit unique device identifier which provides a reference

number that is unique for any device and in any context. The 96 bits of the identifier can

never be altered by the user.

The unique device identifier can be read in single byte and may then be concatenated using

a custom algorithm.

The unique device identifier is ideally suited:



For use as serial numbers



For use as security keys to increase the code security in the program memory while

using and combining this unique ID with software cryptographic primitives and

protocols before programming the internal memory



To activate secure boot processes
