Unique ID

The 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 cryptograhic primitives and protocols before

programming the internal memory.

• To activate secure boot processes
