There is a 96-bit unique ID register you can read which will be unique for each chip.

I wonder if there are some fixed values in the unique device id register.

Yes. Not all 96 bits are unique. Read a few chips to see if that is a concern for your needs.

But how will you determine if any ID value indicates good or bad ?
