LIN Protocol and Physical Layer Requirements Because the whole idea of LIN is to be a simple, cost-effective communication interface, a dedicated communication controller is not implemented. Rather a microcontroller is programmed with the LIN protocol, and used to drive the communication to the transceiver via the serial interface. This ...
