The MCP25625 Click Board™ carries a Microchip CAN controller with an integrated transceiver. It meets the automotive requirement for high-speed operation (up to 1 Mb/s).
Named after the main chip, MCP25625 click also has an RS232 port, which is a standard connector for CAN communications. Additionally, the two CAN wires (CANL and CANH) can also be connected directly through two pins on the right edge of the board.
The click communicates with the target MCU through the SPI interface — although there are additional options that take the load off the target board MCU. To that end, all 16 mikroBUS™ pins are connected. There’s a clock output, a Request To Send, an Interrupt, standby, reset and more. MCP25625 click can work with both 3.3V or 5V logic levels.
