This application note fully describes the working of a
code hopping decoder implemented on a Microchip
PIC16C56 microcontroller. This decoder uses the
secure learn (seed-based) method of learning new
transmitters. This application note describes the vari -
ous KEELOQ
®
code hopping encoders that can be used
with the decoder, the decoder hardware, and the vari-
ous software modules comprising the system. The soft -
ware can be used to implement a stand alone decoder
or integrate with full function security systems. The
decoder supports the Microchip HCS200, HCS300,
HCS301, HCS360, HCS361 and HCS410 KEELOQ
Code Hopping Encoders.
