Compatible with All MCUs, Implementable Without System Redesign

Microchip Technology announced the launch of an external CAN FD (CAN Flexible Data Rate) controller.

The MCP2517FD provides a simplified migration path from CAN 2.0 to CAN FD, enabling designers to gain the benefits of the enhanced CAN FD protocol.

CAN FD offers numerous advantages over the existing CAN 2.0, including faster data rates and expanded data byte messaging. The latest MCP2517FD CAN FD controller works with all microcontrollers (MCUs) and enables easy implementation of CAN FD technology without requiring a complete system redesign.

Since CAN FD adoption and migration are still in the early stages, the number of available CAN FD MCUs is currently limited. Additionally, changing the system MCU can involve significant costs, development time, and associated risks. However, the MCP2517FD enables CAN FD functionality by adding just a single external component, while allowing most of the existing design to be reused as-is.

Furthermore, by utilizing the MCP2517FD, an additional CAN FD channel can be easily added alongside the channels available on the MCU.

Rich Simoncic, Vice President of Microchip's Analog, Power and Interface Business Unit, stated, "The transition from CAN 2.0 to CAN FD has already begun, and designers in the automotive and non-automotive sectors will benefit from the advantages of the enhanced CAN FD protocol. Until now, developers had very limited options when trying to select a CAN FD-capable MCU that perfectly fit their application. The MCP2517FD external CAN FD controller is a practical MCU alternative that maximizes hardware and firmware reuse while minimizing the cost and complexity associated with redesign."
