MCHPMCP2517FDT-H/JHA

Overview

The MCP2517FDT-H/JHA is a stand-alone CAN FD controller from Microchip with an SPI host interface. It offloads CAN protocol handling from the host MCU and provides message buffering, filtering and interrupt signaling over SPI for integration into systems without a native CAN FD peripheral. The device is intended to be paired with an external CAN transceiver to connect to a physical CAN or CAN FD bus.

Why Choose This Part

Using a standalone CAN FD controller lets you add CAN FD support to virtually any MCU that has an SPI port, avoiding the need for a microcontroller with native CAN FD hardware. The SPI register model and built-in message buffers and filtering reduce firmware complexity and offload frame handling and arbitration. Microchip parts are widely supported with datasheets, application notes and reference designs, simplifying hardware and software integration.

Applications

Getting Started

The MCP2517FDT is a controller-only device and requires an external CAN transceiver to connect to the bus; pick a transceiver compatible with your bus voltage and fault requirements. Development typically uses any MCU/toolchain that provides SPI support; if you use Microchip MCUs, MPLAB X IDE and Microchip compilers are convenient and Microchip publishes datasheets and application notes for example code. For bring-up, use a CAN FD-capable bus monitor or CAN analyzer and validate with a CAN transceiver evaluation board or reference design.
