Description
This Application Note describes the working of a KEELOQ® code hopping decoder implemented on a Microchip mid-range MCU (PIC16F873). The software implements a stand-alone decoder integrated with a convenience center master microcontroller. The decoder supports the Microchip?s HCS200, HCS201, HCS300, HCS301, HCS360, and HCS361 KEELOQ hopping code encoders. The decoder supports normal and secure learning. Two manufacturer?s codes allow different manufacturers to share a public key, but retain their own private keys.
