The CAN bus circuit refers to the circuit part of the communication system of the Controller Area Network. It is a high-speed, reliable serial communication protocol, widely used in automotive, industrial automation and other fields. The CAN bus circuit is composed of CAN controller, CAN transceiver and physical layer circuit, which is used to realize data transmission and communication between multiple nodes.
It has the advantages of strong anti-interference ability, long transmission distance and multi-node support, which can realize real-time and reliable data transmission and improve the reliability and performance of the system.
