Renesas RH850/U2C—28nm “zonal-ready” MCU meets a shifting software toolchain reality
2 Min Read March 6, 2026
Renesas adds the RH850/U2C, a 28nm 32‑bit MCU with added connectivity, integration, and safety features for rising zonal and domain ECU needs.
Renesas has expanded its long-standing RH850 automotive MCU family with the RH850/U2C, a new 32-bit device built on a 28nm process. It acts as a lower-end counterpart to the RH850/U2B (high-end) and RH850/U2A (mid-range), with the U2C adding modern vehicle-network connectivity, greater integration, and enhanced safety/security features for ECUs that increasingly play a central role in zonal and domain consolidation.
