This application note describes the design of a
microcontroller-based KEELOQ
®
Transmitter with
receiver Acknowledge using the K EELOQ/AES
encryption algorithm. This transmitter is implemented
on the Microchip PIC16F636 microcontroller.
Descriptions of the encoding process, the encoding
hardware and description of the software modules are
included within this application note. The software was
designed to be backwards compatible with an HCS365
dual transmitter in terms of memory map programming.
This design can be used to implement a secure system
transmitter that has the fl exibility to be designed into
various types of K EELOQ receiver/decoders. The
acknowledge is achieved by using an MRF49XA
transceiver. AN1324
