3.18.3 Controller Area Network (CAN) Interface

The SAM9X75D2G has native support for Controller Area Network (CAN). The SAM9X75 cHybrid shares the CAN interface with the UART signals of the mikroBUS™ connector (J25). Use the mikroBUS Click MIKROE-2299, which embeds a Microchip MCP2542WFD, to connect the SAM9X75 cHybrid to a CAN network.

The MCP2542 is a high-speed CAN transceiver that provides the interface between the CAN protocol controller and the physical two-wire bus. For more information about the MCP2542, refer to the product web page.

The following table shows the CAN interface in the mikroBUS connector signal description.
