Renesas is set to roll out its high-performance R-Car D3 automotive infotainment system system-on-chip (SoC). R-Car 3D is designed to expand the use of 3D graphics instrument clusters (3D clusters) that support 3D graphics displays in entry-class cars. The R-Car D3 system is claimed to achieve both high-performance graphic capabilities while contributing to significant reduction in overall system development cost.

By adopting the R-Car D3, system developers can re-use their 3D graphics development assets, including software and graphics designs from high-end vehicles that adopt high-performance R-Car H3 or R-Car M3 SoCs to entry-level cars. This scalability enables development of easy-to-use and high visibility entry cluster 3D graphics at approximately the same level cost as the existing 2D clusters. In addition, Renesas collaborates with industry-leading partners in the instrument cluster field to further reduce development steps and costs.

The increasing number of connections between the instrument cluster and the various sensors and control devices allows more information about the vehicle and its surroundings to be captured and displayed on the instrument cluster. However, this increases the need for improved visibility from a safety point of view, which is where 3D graphics comes in. The R-Car D3 uses open GL ES 3.1 for 3D graphics drawing, which enables scalability with third-generation R-Car devices. Furthermore, the new SoC uses the same 2D graphics core as the RH850/D1M microcontroller (MCU) for 2D graphics applications. This assures that users will be able to reuse all their software assets and design content assets development from applications ranging from 2D clusters to high-end 3D clusters.
As part of the third-generation R-Car SoC Family, the R-Car D3 supports the ISO 26262 (ASIL-B) automotive functional safety standard, and provides a functional safety support program for implementing safe driving support systems, contributing to the realization of a safe driving experience.

Mass production is scheduled to begin in September 2019 and is expected to reach a volume of 200,000 units per month in September 2020. (Availability is subject to change without notice.) The R-Car D3 product specification is here.
