Description

CPC-USB/ARM7 is a CAN interface for USB ports in a compact and robust metal housing. Due to easy handling and favorable price CPC-USB/ARM7 is suitable for configuration and analysis of CAN systems.

CPC-USB/ARM7 is equipped with a Cortex M3 microcontroller providing onChip CAN and USB controller. By combining the powerful CPU with internal peripherals low latencies can be achieved. The interface is completely supplied via USB, a separate supply for the CAN side is not needed.

It supports 11-bit and 29-bit identifiers. The interface is optionally available with galvanic isolation. In addition also a variant with low speed transceiver TJA1054A is available. For applications, where a higher fault voltage on the CAN bus terminals cannot be avoided, the version HV is available. The use of the transceiver MAX13052 allows voltages up to ±80 V on the CAN bus lines. Also a version with RJ45 CAN connector is available.

For the operating systems Windows and Linux software development kits with identical API are available free of charge. SocketCAN is supported.

Technical Data

Layout and Connection

CPC-USB/ARM7 includes a CAN segment connected by a male plug of type D-Sub9, the pin assignment is complying to CiA DS-102 for the standard version. In addition, the interface includes a USB connector that also carries the supply for CPC-USB/ARM7.
The following table shows the assignment of the CAN connector:

Pin	Name	Description Standard Version	Description Low Speed Version
1	RTL	Not connected	Connected with Pin 2 by a 5K6 resistor and with dedicated Pin of TJA1054 CAN transceiver
2	CAN_L	CAN bus line (dominant low)	CAN bus line (dominant low)
3	GND	CAN Ground	CAN Ground
7	CAN_H	CAN data line (dominant high)	CAN data line (dominant high)
8	RTH	Not connected	Connected with Pin 7 by a 5k6 resistor and with dedicated Pin of TJA1054 CAN transceiver
4, 5, 6, 9	–	Not connected	Not connected

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, standard version	-30	+30	V
Voltage on bus connections, LS version	-27	+30	V
Voltage on bus connections, HS version	-80	+80	V

Any (also temporary) stress in excess of the limiting values may cause permanent damage on CPC-USB/ARM7 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 (idle mode)	n.s.	100	n.s.	mA
Current consumption (operation mode)	n.s.	n.s.	250	mA
Supply voltage	4,0	5,0	5,5	V

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