TSC80C31/80C51

TSC80C31/80C51 with Secret TAG

TEMIC offers special 64-bit identifier called “SECRET

TAG” on the microcontroller chip.

The Secret Tag option is available on both ROMless and

masked microcontrollers.

The Secret Tag feature allows serialization of each

microcontroller for identification of a specific

equipment. A unique number per device is implemented

in the chip during manufacturing process. The serial

number is a 64-bit binary value which is contained and

addressable in the Special Function Registers (SFR) area.

This Secret Tag option can be read-out by a software

routine and thus enables the user to do an individual

identity check per device. This routine is implemented

inside the microcontroller ROM memory in case of

masked version which can be kept secret (and then the

value of the Secret Tag also) by using a ROM Encryption.

For further information, please refer to the application

note (ANM031) available upon request.
