CPC-USB is a CAN interface for USB ports in a compact and robust metal housing. Due to easy handling and favourable price CPC-USB is suitable for configuration and analysis of CAN systems. CPC-USB is equipped with a Cortex M3 microcontroller providing onChip CAN and USB controller. By combining the powerful CPU with internal peripherials low latencies can be achieved. The interface is completely supplied via USB. It supports 11bit and 29bit identifiers. The interface is optionally available with galvanic isolation. In addition a variant with low speed transceiver TJA1054A can be obtained. For applications, where a higher fault voltage on the CAN terminals cannot be avoided, the version HV is available. The use of the transceiver MAX13052 allows voltages up to +-80V on the CAN bus lines. Application development kits for the operating systems Windows and Linux are offered separately. SocketCAN is supported.

Technical Data

Layout and Connection

CPC-USB includes a CAN segment connected by a male plug of type D-Sub 9, the pin assignment is complying to CiA DS-102 standard. In addition, the interface includes a USB connector that also carries the supply for CPC-USB. The following table shows the assignment of the CAN connector:

Pin Name Function
2 CAN_L CAN data line (dominant low)
3 GND Ground
7 CAN_H CAN data line (dominant high)

Limiting Values

Parameter Minimal Maximal Unit
Storage temperature -20 +80 °C
Operating temperature 0 +60 °C
Supply voltage 0 +6 V
Voltage on bus connections -30 +30 V

Any (also temporary) stress in excess of the limiting values may cause permanent damage on CPC-USB 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

Parameter Minimal Typical Maximal Unit
Current consumption n.s. 100 250 mA
Supply voltage 4,0 5,0 5,5 V

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

Scope of Delivery

  • CAN Interface CPC-USB
  • USB Connection Cable
  • User Manual
  • proCANtool CAN-Monitor for operating systems Windows 2000/XP/Vista/7/8
