What series in the NuMicro™ family supports UID (Unique ID)? What to do if the user wants to use a unique ID to encrypt a chip?

User can use the UID (Unique ID) to encrypt all the NuMicro family chips except NUC100AN and NUC100BN Series.

As to UID (Unique ID), Nuvoton will plant the UID into chips as mentioned above and each chip’s UID is different from others. User can provide some judging rules in the firmware code to prevent from stealing the original code and reproducing the same product.
