Microchip MCP2517 FD External CAN FD Controller With SPI Interface
The MCP2517FD is a cost-effective and small-footprint External CAN FD Controller that can connect to a microcontroller per SPI interface, thus providing an easy solution for microcontrollers requiring a CAN FD peripheral or don't have enough CAN FD channels.
The MCP2517FD supports both the Classical format (CAN 2.0B) and CAN Flexible Data Rate (CAN FD) format specified in ISO11898-1:2015.
Note:
The MCP2517FD is a trendy choice for existing embedded systems. It is, however, not recommended for new designs. Microchip suggests using the pin- and functionality compatible MCP2518FD. However, we will refer to the MCP2517FD in this documentation to maintain "backward compatibility" to existing designs.
