Renesas expands 7nm ADAS chip family with V4M
Renesas Electronics has expanded its R-Car Family of system-on-chips (SoCs) for entry-level Advanced Driver Assistance Systems (ADAS).
The Renesas R-Car V4M series provides AI processing for entry-level, cost-sensitive ADAS applications such as front smart camera systems, surround-view systems, automatic parking and driver monitoring systems.
The V4M uses the same 7nm manufacturing process technology as the R-Car V4H series and provides 17TOPS of AI performance for high-speed image processing and precise object recognition using on-board cameras, radar and LiDAR.
This provides the high end for ADAS with pin compatibility within the same series and software compatibility with existing R-Car products, allowing OEMs and Tier-1 suppliers to reuse existing software and reduce engineering costs.
To date, Renesas has shipped over 450 million automotive-grade R-Car devices, including those meeting ASIL D quality rating, which represents the highest rating for risk reduction.
The R-Car V4M and R-Car V4H series feature up to four ARM Cortex-A76 cores delivering up to 81K DMIPS performance for application processing. It also comes with three ARM Cortex-R52 lockstep cores with up to 25K DMIPS performance for real-time operation for ASIL D real-time operation without external MCUs.
It also includes dedicated deep learning and computer vision IP with a 3D Graphic processor Unit (GPU). An Image Signal Processor (ISP) with parallel processing supports machine and human vision and an Image renderer (IMR) provides fisheye distortion correction or other mathematical operations, all with lower power.
The devices provide 9 TOPS/W performance and in a typical full-feature smart camera with an 8-megapixel sensor, the R-Car V4M consumes around 5W, half that of other devices.
The chips support an expandable memory size AUTOSAR software partition and have CAN, Ethernet AVB, TSN and FlexRay interfaces. The bill of materials (BoM) is optimized for NCAP, GSR2, L2+ with a single chip SoC without external MCUs. Renesas also has a dedicated power management ICs (PMIC) and power transistors.
Hailo, Renesas team up for seamless transition from ADAS to automated driving
“We are extending our ADAS offerings to meet the increasing demand for Level 1 and Level 2 ADAS solutions for mass-market vehicles,” said Aish Dubey, Vice President & General Manager, High Performance Computing SoC Business Division at Renesas. “At the same time, we are developing our new 5th Generation R-Car SoCs, which will further bolster our offerings in ADAS, cockpit, gateway, and infotainment segments. We are committed to offer the broadest range of automotive embedded processor solutions for all vehicle classes — from entry-level to luxury-class models — all under a single development platform.”
R-Car Open Access (RoX) Platform Available for SDV Development
Automotive engineers developing with the R-Car V4M series and R-Car V4H series can enjoy the latest features of the full SDV development environment offered by Renesas. The launched R-Car Open Access (RoX) SDV platform integrates all essential hardware, operating systems (OS), software and tools needed for automotive developers to rapidly develop next-generation vehicles with secure and continuous software updates.
RoX allows OEMs and Tier 1 suppliers the flexibility to virtually design a broad range of scalable compute solutions for ADAS, IVI, gateway, and cross-domain fusion systems as well as body control, domain, and zone control systems. The platform comes with a Software Development Kit (SDK) and the AI Workbench, which enables developers to validate and optimize their models and test their applications all in the cloud.
Renesas is sampling the R-Car V4M and R-Car V4H devices to leading automotive manufacturers now, with mass production scheduled in Q1/2026.
