is a CAN-FD interface with galvanic decoupling for USB ports in a robust metal housing.

Special Features


  • CAN FD interface for industrial applications
  • Powerful Cortex M4 microcontroller with internal CAN FD and USB controller
  • Display of USB communication and CAN data transfer via LEDs
  • Supply completely over USB
  • USB 2.0 high speed
  • DC Bus fault protection voltage ±70V
  • Linux socketCAN is supported


CPC­-USB/FD is a CAN FD interface for USB ports in a compact and robust metal housing. Due to easy handling and favourable price CPC­USB/FD is suitable for configuration and analysis of CAN FD systems. CPC­-USB is equipped with a Cortex M4 microcontroller providing onChip CAN FD and USB controller. By combining the powerful CPU with internal peripherials low latencies can be achieved. This is supported by the high speed USB connection. The interface is powered via USB, a separate supply for the CAN side is not needed. The interface includes galvanic isolation. The used CAN FD transceiver tolerates DC fault voltages up to ±70V on the CAN bus lines. Application development kits for the operating systems Windows and Linux are offered separately. SocketCAN is supported.

Technical Data

CPC-­USB/FD includes a CAN segment connected by a male plug of type D­Sub 9, the pin assignment is complying to CiA DS­102. In addition the interface includes a USB connector that also carries the supply for CPC-­USB/FD. The used transceiver meets ISO 11898­2:2016 and ISO 11898­5:2007.

The following table shows the assignment of the CAN connector:

2CAN_LCAN bus line (dominant low)
7CAN_HCAN bus line (dominant high)


Storage temperature-20+80°C
Operating temperature0+60°C
Supply voltage0+6V
Voltage on bus connections-70+70V

Any (also temporary) stress in excess of the limiting values may cause permanent damage on CPC­-USB/FD and other connected devices. Exposure to limiting conditions for extended periods may affect the reliability and shorten the life cycle of the device.
