Controller Area Network (CAN) Module
Controller Area Network Overview
Controller Area Network (CAN) is a multicast shared serial bus standard for connecting electronic
control units (ECUs). CAN was specifically designed to be robust in electromagnetically noisy
environments and can utilize a differential balanced line like RS-485 or a more robust twisted-pair
wire. Originally created for automotive purposes, it is also used in many embedded control
applications (such as industrial and medical). Bit rates up to 1 Mbps are possible at network lengths
below 40 meters. Decreased bit rates allow longer network distances (for example, 125 Kbps at
500 m).
