Local Interconnect Network (LIN) / SAE J2602
LIN/ SAE J2602 is a universal asynchronous receiver-transmitter (UART)-based, single-master, multiple-slave networking architecture originally developed for automotive sensor and actuator networking applications. LIN provides a cost-effective networking option for connecting motors, switches, sensors and lamps in the vehicle. The LIN master node extends the communication benefits of in-vehicle networking all the way to the individual sensors and actuators by connecting LIN with higher-level networks, such as the Controller Area Network (CAN).

Key benefits of a LIN Communications System
- Enables effective communication for sensors and actuators where the bandwidth and versatility of CAN is not required
- Complements CAN as a cost-effective sub-network
- Synchronization mechanism means no quartz oscillator required at slaves
- The LIN/ SAE J2602 protocol can be generated by standard asynchronous communication interfaces (SCI, UART)—no specific hardware required
- No protocol license fee
