KEELOQ®HCS5XX Decoder Family
The HCS5XX decoder utilizes the patented KEELOQ®
code-hopping system and high security learning
mechanisms to make this canned solutions when used
with the HCS encoders to implement uni-directional
remote and access control systems. The HCS5XX
decoders operate over a wide voltage range and can be
used as stand-alone decoders or in conjunction with a
PICmicro® MCU through serial or parallel interface.
Microchip also offers a variety of software decoders that
allows the system designer to integrate the KEELOQ
decoding functions with their application onto a single
PICmicro MCU. The software decoders come as part of a
licensing package (DS40149) and include the decoding
algorithm, receive routines and support various learning
schemes to reduce development time and get the product
to market faster.
