Renesas fast-tracks SDV innovation with R-Car gen 5 SoC
Renesas is expanding its software-defined vehicle (SDV) solution offerings centred around the fifth-generation (Gen 5) R-Car family. The latest device in the Gen 5 family, the R-Car X5H is the industry’s first multi-domain automotive system-on-chip (SoC) manufactured with advanced 3nm process technology. It is capable of simultaneously running vehicle functions across advanced driver assistance systems (ADAS), in-vehicle infotainment (IVI), and gateway systems.
Renesas has begun sampling Gen 5 silicon and now offers full evaluation boards and the R-Car Open Access (RoX) Whitebox Software Development Kit (SDK) as part of the next phase of development. Renesas is also driving deeper collaboration with customers and partners to accelerate adoption.
The R-Car X5H leverages one of the most advanced process nodes in the industry to offer the highest level of integration, performance and power efficiency, with up to 35 percent lower power consumption than previous 5nm solutions. As AI becomes integral to next-generation SDVs, the SoC delivers powerful central compute targeting multiple automotive domains, with the flexibility to scale AI performance using chiplet extensions. It delivers up to 400 TOPS of AI performance, with chiplets boosting acceleration by four times or more. It also features 4 TFLOPS equivalent of GPU power for high-end graphics and over 1,000k DMIPS powered by 32 Arm Cortex-A720AE CPU cores and six Cortex-R52 lockstep cores with ASIL D support. Leveraging mixed criticality technology, the SoC executes advanced features in multiple domains without compromising safety.
As hardware and software become more tightly integrated early in development to support complex E/E architectures, Renesas is adding new capabilities to the RoX development platform. RoX dramatically simplifies development by combining all essential hardware, operating systems, software and tools required to rapidly develop next-generation vehicles with seamless software updates.
To accelerate time-to-market, Renesas now offers the RoX Whitebox Software Development Kit (SDK) for the R-Car X5H, an open platform built on Linux, Android, and XEN hypervisor. Additional support for partner OS and solutions is available, including AUTOSAR, EB corbos Linux, QNX, Red Hat and SafeRTOS. Developers can jumpstart development out of the box using the SDK to build ADAS, L3/L4 autonomy, intelligent cockpit, and gateway systems. An integrated stack of AI and ADAS software enables real-time perception and sensor fusion while generative AI and Large Language Models (LLMs) enable intelligent human-machine interaction for next-generation AI cockpits. The SDK integrates production-grade application software stacks from leading partners such as Candera, DSP Concepts, Nullmax, Smart Eye, STRADVISION and ThunderSoft, supporting end-to-end development of modern automotive software architectures and faster time to market.
Renesas will showcase the capabilities of the R-Car X5H for the first time through a series of invitation-only demos at CES 2026. For more information about how to attend this event, contact sales at: CES26_Info@lm.renesas.com
