ATAK51002-V2

The ATAK51002 evaluation kit provides a complete bidirectional Car Access RKE (Remote Keyless Entry) reference system. The kit includes one base station part and two key fob parts. The implementation of the base station demo was made via the SPI. This provides an easy example how to control the new next generation transceiver from an external host controller. The two key fobs functions are realized via an embedded flash application. This gives an example how to build up a 1-chip application. This type of application helps the customer to minimize the design and significantly reduce the costs in their application.

The fully bidirectional communication is extended by using three RF channel. The key fob transmits the message on three different frequencies in case of a pressed button. This increases significantly the probability to get a successful communication even in a strongly disturbed environment. The base station is constantly in polling mode and searched for a valid message on the three known frequencies. In case of a successful reception, generates the base station part an acknowledge message. This message will be transmitted on the same channel that was used for the reception. This ensures that an undisturbed link will be used which minimizes the probability of a bad communication.

The demo provides an overview of the different application types and includes the key features of the next generation transceiver family.
