Anti-clone function

The SRIX4K provides an anti-clone function that allows the application to authentication the

device. This function uses reserved data that is stored in the SRIX4K memory at its time of

manufacture.

The Authentication system is based on a proprietary challenge/response mechanism which

allows the application software to authenticate any member of the secure memory tag

SRXxxx family from STMicroelectronics (of which the SRIX4K is the prime example). A

reader system, based on the ST CRX14 chip coupler, can check each SRIX4K tag for

authenticity, and protect the application system against silicon copies or emulators.

A complete description of the Authentication system is available under Non Disclosure

Agreement (NDA) with STMicroelectronics. For more details about this SRIX4K function,

please contact your nearest STMicroelectronics sales office.
