The Renesas two wheeler immobilizer reference solution implements security, safety and convenience all in one: Follow Me, Immobilizer, Answerback.

Communication via CAN bus may be established with other modules such as the engine control unit, enabling starting of the bike after authentication, and the cluster for indication.

This demo implements a dual channel Intelligent Power Device (IPD) for blinkers and a single channel IPD for headlamp drive to provide Follow Me extended illumination functionality.
