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.
YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
MCS3142 is an authentic electronic component manufactured by Microchip, categorized under Security ICs / Authentication ICs.
