VN7572 - the FlexRay/CAN FD/LIN Bus Connection via PCIe

The FlexRay network interface VN7572 is ideally suited for the development, simulation or testing of FlexRay networks via the PCIe interface.

The versatile channel combinations for the bus connections to FlexRay, CAN FD and LIN (K-Line) makes it an ideal interface for the laboratory or developer workstation.

Advantages

Simulation of extensive networks due to 2 MB send memory (parallel configuration of more than 1000 messages for transmission)
Cold start of the FlexRay cluster without needing to add a network node
Analysis of the network startup via an independent monitoring unit
2 FlexRay channels (each with channel A and B)
Updating of functional range by FPGA update possible
Variety of channel combinations possible by simply interchangeable transceivers for different bus physics
Optimum performance for CANoe/CANape/CANalyzer applications with CAN, CAN FD, FlexRay, LIN, J1708, and K-Line bus access
Analog/digital IO functionality
Connection for external time synchronization

Application Areas

Flexible analysis of FlexRay networks and ECUs in combination with the bus systems CAN FD as well as LIN (K-Line)
Precise time analysis of communication data
Analysis and test of ECUs and gateway applications
Measurement and calibration of ECUs via XCP (XCP on FlexRay, XCP on CAN).

Additionally, customer-specific applications can be created by using FlexRay-specific libraries.

Functions

FlexRay:

Dynamic reconfiguration of the CC buffers
Transmission and reception of data and null frames
Detection of invalid frames
Cycle multiplexing
In-cycle response
Hardware-based incrementing of a payload area
Support of PDUs
FlexRay gateway (channel A and B)
Startup + asynchronous monitoring allows detection of FlexRay frames and symbols, even before the communi-cation controller has synchronized itself to the bus.

General:

Synchronization with several devices and other bus systems (e.g. CAN(FD), LIN)
Low PC loading due to Direct Memory Access DMA
Very short latency times
Support of CAN FD up to 8 MBit
Fast CAN flashing through hardware-based flash sequence support
Extended LIN stress functions, e.g. for LIN 2.1 confor-mance tests
