Overview
The MCP2518FDT-E/SLVAO is a cost-effective and small-footprint CAN FD (Controller Area Network Flexible Data Rate) controller developed by Microchip Technology. This device is designed to be easily integrated with microcontrollers that have an available SPI (Serial Peripheral Interface) and either lack a CAN FD peripheral or require additional CAN FD channels. It supports both CAN 2.0B and CAN FD formats, conforming to the ISO 11898-1:2015 standard. The MCP2518FD is particularly useful for adding CAN FD functionality to existing microcontroller systems without the need for complex hardware modifications.
