Renesas has expanded its RH850 family of 28nm automotive microcontrollers with new products specifically designed for body control, chassis, and safety applications.
Context
Renesas Electronics has expanded its automotive semiconductor portfolio with the March 4, 2026, launch of the RH850/U2C, a 32-bit microcontroller manufactured on an advanced 28nm process. Positioned as a cost-effective solution, it completes a tiered lineup alongside the existing mid-range U2A and high-end U2B devices. The chip is specifically optimized for body control, chassis, and safety systems—such as battery management and lighting—as the industry transitions toward centralized, zone-based electronic architectures.
The RH850/U2C integrates up to four CPU cores running at 320 MHz and provides 8 MB of on-chip flash memory. Crucially, it supports high-bandwidth interfaces like Ethernet TSN and CAN-XL, enabling the data speeds necessary for modern software-defined vehicles. By facilitating a smooth migration path from older 40nm legacy hardware, Renesas is strengthening its competitive stance against Infineon and NXP while ensuring compliance with stringent ASIL D functional safety standards.
