Local Interconnect Network (LIN) is a serial network protocol that is used for communication between parts inside a vehicle. Can was seen as a bit too expensive, while looking for a cheaper alternative the LIN was born via the LIN Consortium. LIN enables cost-effective communication with sensors and actuators, being the lowest level of hierarchical network. The features of CAN are no longer required.
MC33663 integrates two physical layer LIN bus dedicated to automotive LIN sub-bus applications. Its is compatible with LIN protocol specifications 2.1 and SAEJ2602-2 while maintaining high immunity against electromagnetic interference. The MC33663 is compatible with both 5.0 and 3.3 V digital inputs with no external components required.
