Renesas Electronics Corporation (TSE:6723), a leading supplier of advanced semiconductor solutions, has unveiled its latest additions to the R-Car Family of system-on-chips (SoCs), designed specifically for entry-level Advanced Driver Assistance Systems (ADAS). The newly introduced R-Car V4M series and the expanded R-Car V4H series offer impressive AI processing and high CPU performance, effectively balancing performance with power consumption. These devices excel in TOPS/W performance, making them perfect for cost-sensitive ADAS applications such as front smart cameras, surround-view systems, automatic parking, and driver monitoring systems.
Utilizing the advanced 7-nm manufacturing process, the R-Car V4M series delivers deep learning performance of up to 17 TOPS, along with high-speed image processing and precise object recognition through on-board cameras, radar, and LiDAR. With the addition of the R-Car V4M and V4H series, customers can select the most suitable SoC from Renesas’ scalable ADAS portfolio, ensuring advanced AI capabilities and power efficiency to meet diverse application requirements. Notably, these devices maintain pin compatibility within the same series and software compatibility with existing R-Car products, enabling OEMs and Tier-1 suppliers to leverage existing software and minimize engineering costs.
Aish Dubey, Vice President & General Manager of the High Performance Computing SoC Business Division at Renesas, commented, “We are enhancing our ADAS offerings to address the growing demand for Level 1 and Level 2 solutions in mass-market vehicles. Simultaneously, we are developing our upcoming 5th Generation R-Car SoCs, which will strengthen our ADAS, cockpit, gateway, and infotainment solutions. Our commitment is to provide a comprehensive range of automotive embedded processor solutions across all vehicle classes, from entry-level to luxury, under a unified development platform.”
The R-Car V4M and V4H series feature up to four Arm® Cortex®-A76 cores that deliver up to 81K DMIPS for application processing, alongside three Arm Cortex-R52 lockstep cores providing up to 25K DMIPS for real-time operations. The power efficiency of the new devices is remarkable, achieving 9 TOPS/W performance due to their integrated design and cutting-edge manufacturing process. For instance, a typical full-feature smart camera with an 8-megapixel sensor powered by the R-Car V4M consumes around 5 watts—50% less than comparable devices on the market.
To date, Renesas has shipped over 450 million automotive-grade R-Car devices, including those rated ASIL D, the highest safety standard for risk reduction.
R-Car Open Access (RoX) Platform for SDV Development
Automotive engineers utilizing the R-Car V4M and V4H series can access the latest features of Renesas’ full SDV development environment. The newly launched R-Car Open Access (RoX) platform integrates all necessary hardware, operating systems, software, and tools for automotive developers to efficiently create next-generation vehicles with secure, continuous software updates. RoX provides OEMs and Tier-1 suppliers the flexibility to design a wide range of scalable compute solutions for ADAS, in-vehicle infotainment (IVI), gateway systems, and more. The platform includes a Software Development Kit (SDK) and AI Workbench, enabling developers to validate and optimize models and applications in the cloud.
