What is LIN?

LIN bus is a supplement to CAN bus. It offers lower performance and reliability – but also drastically lower costs.

• Low cost option (if speed/fault tolerance are not critical)
• Often used in vehicles for windows, wipers, air condition etc..
• LIN clusters consist of 1 master and up to 16 slave nodes
• Single wire (+ground) with 1-20 kbit/s at max 40 m bus length
• Time triggered scheduling with guaranteed latency time
• Variable data length (2, 4, 8 bytes)
• LIN supports error detection, checksums & configuration
• Operating voltage of 12V
• Physical layer based on ISO 9141 (K-line)
• Sleep mode & wakeup support
• Most newer vehicles have 10+ LIN nodes
