Flexible Interface for the CAN FD, LIN, FlexRay and Ethernet Connection via USB

VN7640 - Flexible Interface for the CAN FD, LIN, FlexRay and Ethernet Connection via USB

What is the VN7640 Network Interface?

The network interface VN7640 provides a flexible interface for FlexRay, CAN FD, LIN, K-Line and J1708 applications via USB. In addition, various Ethernet applications are supported.

The various channel combinations for the bus connections makes it an ideal interface for the laboratory or developer workstation.


  • Variety of channel combinations possible by simply interchangeable transceivers for different bus physics
  • Updating of functional range by FPGA update possible
  • Optimum performance for CANoe/CANape/CANalyzer applications with CAN, CAN FD, FlexRay, LIN, J1708, and K-Line bus access
  • Support of Ethernet applications, e.g. DoIP or measurement / calibration via XCP on Ethernet
  • Analog/digital IO functionality

Application Areas and Functions

  • Remaining bus simulation, gateway application, analysis and testing of networks and ECUs in combination with the bus systems CAN FD, LIN (K-Line), and FlexRay
  • Diagnostics (including Diagnostics over IP) and flashing of ECUs
  • Measurement and calibration of ECUs via XCP  (XCP on FlexRay, XCP on CAN, XCP on Ethernet)

In addition, the included libraries allow the user to create own applications quickly and easily.


  • Support of CAN FD up to 8 MBit
  • FlexRay gateway (channel A)
  • Diagnostic communication via DoIP
