Ultimate Kee Loq Technology, the Next Generation of Security Featuring MCS3142 Dual Kee Loq Encoder Summary Microchip Technology has had a long history as a major supplier in the security industry primarily utilizing our proprietary, royalty-free Kee Lqo Hopping Code Technology, an industry proven technology used worldwide by leading manufacturers, to provide additional security to their applications for more than 15 years. The Ultimate Kee Lqo Protocol is a new timer-based solution offering enhancements to the Classic Kee Lqo Protocol structure such as industry-standard AES-128 block cipher, programmable 32-bit serial number, programmable 128-bit encryption key and Kee Lqo 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. Ultimate KeeLoq Features The entire structure is available in the MCS3142 Dual Timer driven messages Kee Lqo Encoder, which provides a complete turnkey solution. Time stamped events The addition of our new Ultimate Kee Lqo Protocol provides Industry standard AES-128 encryption the customer the ability to develop highly secure Secure learn mode for pairing authentication applications for a variety of markets such as Time recovery after power loss security systems (keypads, remote sensors and access control), remote keyless entry (automotive) and Operating Features authentication (identity and property) applications.

The kit demonstrates two security protocols: Ultimate Kee Loq Protocol and Classic Kee Loq Protocol. It contains a four-button key fob transmitter based on the MCS3142 Dual Kee Loq Encoder, receiver PICtail daughterboard, and Embedded Security Development Board. The software download contains a Graphical User Interface (GUI) to assist with additional development work. MPLAB X Integrated Development Environment (IDE) MPLAB X IDE is a software program that runs on a PC (Windows, MAC OS, Linux) to develop applications for Microchip microcontrollers and digital signal controllers. It is called an Integrated Development Environment (IDE) because it provides a single integrated environment to develop code for embedded microcontrollers.
