Renesas Electronics Corporation has developed three system-on-chip (SoC) technologies aimed at automotive multi-domain electronic control units (ECUs), combining AI acceleration, chiplet support, and enhanced power management as a foundation for next-generation electrical/electronic architectures . The company presented these developments at the International Solid-State Circuits Conference 2026 in San Francisco . As software-defined vehicles evolve, automotive SoCs must support multiple concurrent workloads, scale through chiplet integration, and comply with stringent functional safety requirements . Increasing device complexity and performance also place pressure on power efficiency and automotive-grade quality .
