VN7572

Maximum Performance and Flexibility for FlexRay

The VN7572 FlexRay network interface is designed for the development, simulation, and testing of FlexRay networks via the PCIe interface.

Versatile channel combinations for FlexRay, CAN FD, and LIN (K-line) make the interface a powerful solution for laboratory environments and engineering workstations.

Highlights

Efficient simulation of large networks: 2 MB send memory allows parallel configuration of more than 1000 FlexRay messages.
Autonomous FlexRay cluster startup: Enables a cold start of the FlexRay cluster without requiring an additional network node.
Detailed startup analysis: An independent monitoring unit enables precise analysis of network startup behavior.

Flexible bus combinations: Interchangeable transceivers support versatile combinations of FlexRay, CAN FD, and LIN bus physics.
High tool performance: Optimized for CANoe, CANape, and CANalyzer applications with access to CAN, CAN FD, FlexRay, LIN, J1708, and K‑Line.

Functions

FlexRay

Dynamic reconfiguration of CC buffers.
Sending and receiving data and null frames.
Detection of invalid frames.
Cycle multiplexing.
In-cycle response.
Hardware-based incrementing of a payload range.
PDU support.
FlexRay gateway (channels A and B).
Startup + asynchronous monitoring detects FlexRay frames and symbols before the communication controller is synchronized to the bus.

General

Synchronization with multiple devices and with other bus systems (e.g., CAN/CAN FD, LIN).
Low PC load due to Direct Memory Access (DMA).
Very short latency times.
Support for CAN FD up to 8 Mbit.
Fast CAN flashing via hardware-based flash sequence support.
Advanced LIN stress functions, e.g., for LIN 2.1 conformance tests.
CAPL on board for CAN and FlexRay
