This automotive computing platform enables integration of ADAS, infotainment and gateway functions without compromising safety and performance.
The shift toward software defined vehicles is reshaping automotive computing. Automakers must now unify ADAS, infotainment, gateway and AI workloads on a single platform, all while maintaining functional safety, high performance and strict power budgets. This unification is one of the toughest challenges in modern vehicle designs.
Renesas Electronics is addressing this shift with its 5th generation R Car platform, built around the R Car X5H automotive system on chip. Manufactured using advanced 3 nm process technology, the chip is designed to support multiple vehicle domains at the same time, including ADAS, infotainment and gateway applications on a single device.
To support early development, Renesas is providing silicon samples of the system along with full evaluation boards and the system access to RoX Whitebox Software Development Kit. These tools allow developers to begin building and testing software defined vehicle architectures before production hardware is finalized.
The chip delivers high computing performance with improved power efficiency, offering up to 35% lower power consumption compared to earlier generations. It supports scalable AI processing, delivering up to 400 TOPS of performance with chiplet based acceleration. The SoC also integrates high performance CPU cores alongside safety focused lockstep cores, enabling mixed criticality workloads and compliance with automotive safety requirements.
Renesas is expanding the SDK to simplify software development. The open platform supports Linux, Android, and virtualization, and integrates AI, ADAS, and cockpit software from ecosystem partners, helping automakers and Tier 1 suppliers reduce development time.
Key features include :
- R Car X5H multi domain automotive SoC built on 3 nm technology
- Simultaneous support for ADAS, infotainment, and gateway functions
- Scalable AI performance up to 400 TOPS
- Improved power efficiency compared to previous generations
- Open RoX Whitebox SDK for faster SDV development
Together, the SoC and the SDK platform offer a practical foundation for building safer, more scalable and more efficient software defined vehicles.
