DESCRIPTION

The HCS410 is a code hopping transponder device designed for secure entry systems. The HCS410 utilizes the patented KEELOQ? code hopping system and bi-directional challenge-and-response for logical and physical access control. High security learning mechanisms make this a turnkey solution when used with the KEELOQdecoders. The encoder keys and synchronization information are stored in protected on-chip EEPROM.
