Our external CAN controllers are economical and flexible solutions for using the SPI interface to add CAN or CAN Full Duplex (CAN FD) capability to the microcontroller (MCU) of your choice or extend the number of CAN FD channels if your MCU doesn’t have enough. We also provide devices that enable you to quickly and easily add CAN FD capability to an existing design without having to change your system MCU. Our external CAN FD controller solutions maximize reuse of your existing hardware and firmware, so you can implement the CAN FD protocol’s faster data rates and data byte message expansion in your system without a complete redesign. Our ecosystem of development tools, software and demo code will help speed up your application development and lower your design risk.

What Type of CAN Peripheral Device Do You Need?

Featured Product


MCP2518FD External CAN FD Controller with SPI Interface

This cost-effective and small-footprint external CAN FD controller can be easily added to an MCU with an available SPI interface. It enables you to implement a CAN FD channel in an MCU that is either lacking a CAN FD peripheral or that doesn't have enough CAN FD channels for your application.

Quick Glance:

  • External CAN FD controller with support for CAN 2.0B and CAN FD networks
  • Low-power mode
  • AEC-Q100 Grade 0 and 1 qualified
