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
Application Areas
- 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.
