Unique ID

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:

●

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 crytograhic primitives and protocols

before programming the internal memory.

●

To activate secure boot processes
