VN7640 - FlexRay/CAN FD/LIN/Ethernet Interface for USB or Ethernet

The VN7640 interface is a flexible solution for FlexRay, CAN FD, LIN, K-Line and J1708 applications. Additionally, different use cases are supported for Ethernet.

Due to the various channel combinations the VN7640 is an ideal interface for laboratory or developer workstation. Because of its compact and robust design, it is also suitable for mobile applications.

Advantages

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
Connection for external time synchronization
Accurate time analysis of the communication data
Robust housing
