Introduction to the Controller Area Network (CAN)

A controller area network (CAN) is ideally suited to the many high-level industrial protocols embracing CAN and ISO-11898:1993 as their physical layer. Its cost, performance, and upgradeability provide for tremendous flexibility in system design. This application report presents an introduction to the CAN fundamentals, operating principles, and the implementation of a basic CAN bus with TI’s CAN transceivers and DSPs. The electrical layer requirements of a CAN bus are discussed along with the importance of the different features of a TI CAN transceiver.

In this app note, Steve Corrigan of TI provides a primer on Controller Area Network (CAN) basics.
