USB/CAN Interface CPC-USB/ARM7

Product catalog summary

Overview
The CPC-USB/ARM7 is a USB/CAN interface designed for configuration and analysis of CAN systems. It features a powerful Cortex M3 microcontroller with integrated CAN and USB controllers, housed in a compact metal casing. The device is powered entirely via USB, eliminating the need for a separate power supply for the CAN side.

Special Features

Supports CAN protocols 2.0A and 2.0B.
LED indicators for USB communication and CAN data transfer.
Optional galvanic isolation between CAN and USB.
Optional low-speed transceiver TJA1054A and ±80 V tolerant CAN transceiver MAX13052.
Optional RJ45 CAN connector.
Supports Linux socketCAN.
Free development kits for Windows and Linux.

Description
The CPC-USB/ARM7 is suitable for both configuration and analysis of CAN systems due to its ease of use and affordability. It offers low latency by combining a powerful CPU with internal peripherals. Variants with galvanic isolation and different transceivers are available to accommodate various application needs.

Technical Data
The interface includes a CAN segment connected via a D-Sub9 male plug, compliant with CiA DS-102 standards, and a USB connector that supplies power. The pin assignment for the CAN connector is detailed, with specific configurations for standard and low-speed versions.

USB/CAN Interface USB/CAN Interface CPC-USB/ARM7Special Features • Powerful Cortex M3 microcontroller with internal CAN and USB controller • Display of USB communication and CAN data transfer via LEDs • Supply completely over USB • Optional with galvanic isolation between CAN and USB • Optional with low speed transceiver TJA1054A • Optional with ±80 V tolerant CAN transceiver MAX13052 • Optional available with RJ45 CAN connector • Linux socketCAN is supported • Free of charge development kits for Windows 7/8.x/10/11 and Linux 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. 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 MAX 13052 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.
