Application ReportSLOA101 - August 20021 Introduction to the Controller area Network (CAN)Steve CorriganHPLABSTRACTA Controller area Network (CAN) is ideally suited to the many high-level industrial protocolsembracing CAN and ISO 11898 as their physical layer. Its cost, performance, andupgradeability provide for tremendous flexibility in system design. This paper presents a briefintroduction to the CAN operating principles, the implementation of a basic CAN bus usingTexas Instrument s CAN transceivers and DSPs, and a discussion of the robust errordetection and fault confinement mechanisms. Some of the properties of CAN, especiallyrelating to the electrical layer and features of transceiver products, are then discussed at atutorial.
