HCS361 - Microchip Technology

HCS361 KEELOQ CODE HOPPING ENCODER

The HCS361 is a code hopping encoder designed for secure Remote Keyless Entry (RKE) systems. The HCS361 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 remote keyless entry systems and access control systems. The HCS361 combines a 32.
