●DESCRIPTION
●The HCS200 from Microchip Technology Inc. is a code hopping encoder designed primarily for Remote Key less Entry (RKE) systems. The device utilizes the KEELOQ® code hopping technology, incorporating high security, a small package outline and low cost. The HCS200 is a perfect replacement of fixed code devices in unidirectional remote keyless entry systems and access control systems.
