DescriptionCPCUSB/FD is a CAN 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. CPCUSB 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 in preparation.

CPCUSB/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 CPCUSB/FD. The used transceiver meets ISO 118982:2016 and ISO 118985:2007.
The following table shows the assignment of the CAN connector:
|2||CAN_L||CAN bus line (dominant low)|
|7||CAN_H||CAN bus line (dominant high)|
|Voltage on bus connections||-70||+70||V|
Any (also temporary) stress in excess of the limiting values may cause permanent damage on CPCUSB and other connected devices. Exposure to limiting conditions for extended periods may affect the reliability and shorten the life cycle of the device.
|Current consumption (idle mode)||–||100||–||mA|
|Current consumption (operation mode)||–||–||250||mA|
All values, unless otherwise specified, refer to a supply voltage of 5V and an environmental temperature of 20°C.
