The LIN is a soft core of the Local Interconnect Network (LIN). This interface is a serial communication protocol, designed primarily to be used in automotive applications. Compared to CAN, LIN is slower, but thanks to its simplicity, is much more cost effective. Our Core is best suited for communications between intelligent sensors and actuators when the bandwidth and adaptability of CAN are not necessary. Between a microprocessor/microcontroller and a LIN bus, the LIN core acts as an interface. It can work as master or slave LIN node, depending on a work mode, determined by the microprocessor/microcontroller. Our controller supports transmission speed between 1 and 20kb/s, which allows it to transmit and receive LIN messages compatible to LIN 1.3. LIN 2.1 and the newest 2.2. The reported information status includes the type and condition of transfer operations being performed by the LIN, as well as a wide range of LIN error conditions (overrun, framing, parity, timeout). Our Core includes programmable timer, which allows to detect timeout and synchronization error. The LIN is described at RTL level, empowering the target use in FPGA and ASIC technologies.
