Renesas Ethernet TSN Demonstrator

Next-Generation Automotive Networking

Prototyping Platform for Deterministic Ethernet

The Renesas Ethernet TSN demonstrator aims to visualize the network key performance indicators:

THROUGHPUT – LATENCY – JITTER

in a TSN type of deterministic Ethernet framework. Its intention is to
demonstrate and evaluate the effect and benefit of IEEE 802.1 TSN
protocol features such as frame preemption, ingress policing, timeaware
shaping, and many more.

Future Development

Based on the demonstrator and as the next evolution step, Renesas and CETITEC are preparing a Multi Gateway ECU as a development platform for automotive customers.

This ECU in an automotive housing allows Gateway operation of TSN Ethernet with the traditional automotive communication channels supported by an innovative software package.

To support SoA (Service-oriented Architecture) type of applications, this ECU includes a powerful R-Car H3 SoC device as performance controller, as well as an RH850-based MCU for control type of operations.
