MCP2517FD-H/JHA: Microchip's High-Performance CAN FD Controller for Automotive and Industrial Networks

The evolution of in-vehicle networking and complex industrial automation systems demands communication controllers that offer higher bandwidth, greater data throughput, and superior reliability. Addressing these critical needs, Microchip Technology's MCP2517FD-H/JHA stands out as a premier standalone Controller Area Network with Flexible Data-Rate (CAN FD) controller. This device is engineered to seamlessly integrate into microcontroller-based applications, providing a robust and feature-rich solution for next-generation network designs.

A key advancement of the MCP2517FD is its support for the CAN FD protocol, which significantly enhances the capabilities of traditional CAN networks. While classic CAN is limited to an 8-byte data field and lower speeds, CAN FD allows for data packets of up to 64 bytes and enables a faster, switchable data rate during the payload phase of a message. This results in a dramatic increase in bandwidth, making it ideal for applications requiring the transfer of large amounts of data, such as advanced driver-assistance systems (ADAS), electric vehicle control units, and high-speed industrial machinery.

The MCP2517FD-H/JHA is designed for maximum flexibility and ease of integration. It interfaces with a host microcontroller (MCU) through a standard Serial Peripheral Interface (SPI), allowing it to augment even microcontrollers without a built-in CAN peripheral. This feature provides designers with the freedom to choose their preferred MCU while still achieving high-performance CAN FD connectivity. The controller supports both CAN 2.0B and CAN FD specifications, ensuring backward compatibility with existing CAN networks while paving the way for future upgrades.

Beyond its core protocol support, the device incorporates several features that enhance system robustness and simplify development. It includes two configurable transmit queues and three dedicated receive buffers, which help manage high-priority messages and prevent data loss in congested network environments. Its built-in FIFO (First-In, First-Out) objects offer additional, highly configurable buffering for both transmission and reception, providing developers with sophisticated message handling capabilities.

Targeting harsh operating environments, the MCP2517FD-H/JHA is built to meet the stringent requirements of automotive and industrial applications. It operates over a wide temperature range and is designed for high immunity to Electromagnetic Interference (EMI), ensuring reliable performance even in the presence of significant electrical noise.

ICGOODFIND: The MCP2517FD-H/JHA from Microchip is a high-performance, flexible, and robust CAN FD controller that empowers designers to build more data-intensive and reliable networks for the automotive and industrial markets. Its support for the advanced CAN FD protocol, coupled with its sophisticated message handling and SPI interface, makes it an essential component for modern connected systems.
