External CAN and CAN FD Controllers + Transceiver

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.
