MCHPMCP2517FDT-H/SL

Overview

The MCP2517FDT-H/SL is a compact, external CAN FD controller that interfaces with microcontrollers via a high-speed SPI bus. It supports both CAN 2.0B and CAN FD (Flexible Data Rate) protocols, allowing for data bit rates up to 8 Mbps. Designed for harsh environments, this H-temp grade variant operates up to 150 degrees Celsius, making it suitable for automotive and high-temperature industrial applications.

Why Choose This Part

The controller features a large 2 KB RAM buffer for message objects and supports up to 31 configurable FIFOs, providing significant flexibility for transmit and receive operations. Its low power consumption of 20 mA in run mode and 10 uA in sleep mode makes it efficient for battery-backed systems. The inclusion of a 32-bit time stamp and bus health diagnostics simplifies system debugging and synchronization.

Applications

Getting Started

To evaluate this controller, engineers often use the MCP2517FD CAN FD Motherboard or the Click range of boards for rapid prototyping. Development requires an SPI master capable of at least 20 MHz to handle high CAN FD data rates effectively. Microchip provides the CAN FD Controller Tool and C-based drivers within the MPLAB Code Configurator (MCC) to streamline register initialization.
