USB/CAN Interface CPC-USB/embedded

CPC-USB/embedded is a CAN interface for internal USB ports. Due to its compact size it is eminently suitable for applications in embedded PCs.


CPCUSB/embedded is a CAN interface for internal USB ports. Due to its compact size it is eminently suitable for applications in embedded PCs. It is installed directly at a SUBD9 case opening or a slot panel and wired with the included cable to a pin connector of an internal USB interface of the mainboard. The interface is equipped with a Cortex M3 microcontroller providing onChip CAN and USB controllers. By combining the powerful CPU with internal peripherials low latencies can be achieved. The interface is powered via USB, a separate supply for the CAN side is not needed. CPCUSB/embedded provides galvanic decoupling between CAN and USB and has an extended operating temperature range. It supports 11Bit and 29Bit CAN identifiers. Application development kits for the operating systems Windows and Linux are offered additionally. Linux socketCAN is supported as well.

Special Features

  • Supports CAN protocols 2.0A and 2.0B
  • Supply over USB
  • Galvanic isolation
  • Firmware flashable over USB
  • Development kits for Windows 2000/XP/Vista/7/8.x and Linux available
  • Linux socketCAN is supported


Technical Data

Layout and connection CPCUSB/embedded includes a CAN segment connected by a male plug of type DSub9,the pin assignment is complying to CiA DS102 standard. In addition, the interface includes a USB connector that also carries the supply for CPCUSB/embedded.

The following table shows the assignment of the CAN connector:

Limiting Values

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

Nominal Values

All values, unless otherwise specified, refer to a supply voltage of 5V and an environmental temperature of 20°C.


Scope of Delivery

  • CAN Interface CPCUSB/embedded
  • USB Connection Cable
  • User Manual
  • proCANtool CAN‑Monitor for operating systems Windows 2000/XP/Vista/7/8.x
