Code Hopping Decoder
DESCRIPTION
The Microchip Technology Inc. HCS515 is a code hop-
ping decoder designed for secure Remote Keyless
Entry (RKE) systems. The HCS515 utilizes the pat-
ented code hopping system and high security learning
mechanisms to make this a canned solution when used
with the HCS encoders to implement a unidirectional
remote and access control systems. The HCS515 can
be used as a stand-alone decoder or in conjunction
with a microcontroller.
