GENERAL DESCRIPTION

The HCS365 is a code hopping encoder designed for secure Remote Keyless Entry (RKE) and secure remote control systems. The HCS365 utilizes the KEELOQ® code hopping technology, which incorporates high security, a small package outline, and low cost to make this device a perfect solution for unidirectional authentication systems and access control systems.
