In automobiles, the LIN (Local Interconnect Network) is a low-priced serial communication system that developed specifically for simple electronic assemblies to be cross-linked.
It is particularly useful in areas where sensors and actuators are simple enough to be networked but efficiency is not required. The sub-system for example doors, seats, steering wheel are generally connected with LIN (Local Interconnect Network) are also connected to CAN-based networks such as body, chassis. Simple access is provided with CAN-based diagnostic and service tools.
The communication principle for KIN technology is a serial single-wire communication protocol that is based on the SCI interface standard i.e. (UART). The LIN bus is controlled by the master with a maximum latency time.
LIN got a special characteristic where slave devices are synchronized via the bus with low-priced nodes to be implemented with simple resonant circuits. The communication of data takes place with a 12 V single wire and 20 Kbit/s as the maximum data transmission rate.
A typical LIN system is designed up to 16 nodes due to only 64 identifiers and with relatively low bit rate.
The low cost of the LIN system is contributed because of the synchronization of the clock, simple UART communication, and the single wire medium.
