Description

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 includes a CAN interface that supports 11-Bit and 29-Bit CAN identifiers as well as a 32-bit microcontroller of type LPC2119 with 128kByte Flash and 16kByte RAM. The interface is supplied via USB, a separate supply for the CAN side is not needed. The interface is optionally available with galvanic isolation. In addition, a variant with low speed transceiver TJA1054 for automotive environments can be obtained. Application development kits for the operating systems Windows and Linux are offered separately.

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	+70	°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.
