PCF7935AS

Product Summary

The PCF7935AS, SECT is a programmable Security Transponder employing challenge/response authentication ideally suited for contactless authentication and memory access between a basestation and the transponder. The SECT PCF7935AS features a powerful security algorithm for vehicle immobiliser applications. The PCF7935AS is fully compatible with the PCF7931 read only and PCF7930 read/write transponder family, providing means for downward compatibility. The transponder PCF7935AS features 1152 bit of non-volatile memory (EEPROM) from which 768 bit are reserved for user data storage. User data and configuration data may be exchanged in password mode for advanced pre-personalisation techniques. Memory access flags and a 56 bit password enable read and/or write protection of data. The SECT PCF7935AS performs a 48 bit challenge/response authentication, employing a 128 bit Secret Key. In addition the SECT supports a 32 bit device identification number. The transponder power supply and system clock is derived from the magnetic component of the RF field generated by the basestation. The transponder PCF7935AS is assembled in a small leadless stick shaped plastic package.
