DESCRIPTION

The Microchip Technology Inc. HCS512 is a code hopping decoder designed for secure Remote Keyless Entry (RKE) systems. The HCS512 utilizes the patented KEELOQ code hopping system and high security learning mechanisms to make this a canned solution when used with the HCS encoders to implement a unidirectional remote keyless entry system.
