Unique ID
STM8L101xx 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 bytes and may then be concatenated
using a custom algorithm.
The unique device identifier is ideally suited:
