Built on a 28-nm process, the Renesas RH850/U2C automotive microcontroller delivers robust connectivity and security for modern E/E architectures. This 32-bit MCU expands the RH850 lineup with a cost-optimized option for chassis and safety systems, battery management, body control, and other ASIL D–rated applications.

The device integrates four RH850 CPU cores running at up to 320 MHz, including two lockstep cores, and up to 8 MB of on-chip flash memory. It combines 10BASE-T1S and TSN Ethernet (1 Gbps/100 Mbps), CAN XL, and I3C with widely used interfaces such as CAN FD, LIN, UART, CXPI, I2C, I2S, and PSI5.

In addition to functional safety support up to ASIL D under ISO 26262, the RH850/U2C meets current cybersecurity requirements in accordance with ISO/SAE 21434. The MCU integrates hardware acceleration for cryptographic algorithms, ranging from post-quantum cryptography (PQC) to those mandated by current Chinese and other international regulations.

The RH850/U2C is available in BGA292 and HLQFP144 packages.
