Tech First Kit-Microchip-DM303007-EVK

The KEELOQ 3 Development Kit consists of a controller board, a radio receiver board and two handheld transmitters.

The controller board uses a modular approach so it can be used in various configurations. The board features a 14-pin PICkit Tail connector to accommodate a radio receiver board and a 28-pin PICkit Tail connector for expansion. The PIC16F886 microcontroller on the controller board can be programmed in circuit using the onboard PICkit 2 connector. Also, it can be connected to the PICkit Serial Analyzer for serial communication with a PC.

One receiver board containing the Microchip rfRXD0420 ASK radio receiver chip is included in  the kit.

Two hand-held transmitters are included with the KEELOQ 3 Development Kit. One uses a standard HCS362 hardware encoder and the other uses a PIC16F636-I/MLPIC16F636-I/ML microcontroller.

To assist in KEELOQ encoder/decoder development and programming, an MPLAB KEELOQ plug-in is also supplied. A separate graphical user interface (GUI) is supplied to demonstrate I2C communication using the PICkit serial analyzer connection.

In addition to the traditional KEELOQ encryption/decryption routines, KEELOQ/AES and KEELOQ/XTEA encryption/decryption routines are available by ordering the CD “Advanced Security Algorithms for KEELOQ Systems” (DS51813).
