Hopping Encoder 8-Pin PDIP

The HCS360 from Microchip Technology Inc. is a code hopping encoder designed primarily for Remote Keyless Entry (RKE) systems. The device utilizes the KEELOQ code hopping technology, incorporating high security, a small package outline and low cost. The HCS360 is a perfect replacement of fixed code devices in unidirectional remote keyless entry systems and access control systems.
