MCS3142

The new  MCS3142 Dual KeeLoq  Encoder provides a complete turnkey solution utilizing the Ultimate KeeLoq  Protocol,  a new timer-based solution offering enhancements to the Classic KeeLoq  Protocol structure such as industry-standard AES-128 block cipher, programmable 32-bit serial number, programmable 128-bit encryption key and KeeLoq  Secure Learn Mode (128-bit Seed). It incorporates a timer-driven message counter which continuously increments, independent of events, to provide a better, more secure solution. The time-keeping functionality provides additional protection against capture and replay attack techniques.

The addition of our new Ultimate KeeLoq  Protocol provides the customer the ability to develop highly secure authentication applications for a variety of markets such as
security systems (keypads, remote sensors and access control), remote keyless entry (automotive) and
authentication (identity and property) applications.
