Overview

Description

The RH850/U2A MCU is the first member of Renesas’ cross-domain MCUs, a new generation of automotive-control devices, designed to address the growing need to integrate multiple applications into a single chip to realize unified electronic control units (ECUs) for the evolving electrical/electronic architecture (E/E architecture). Based on 28 nanometer (nm) process technology, the 32-bit RH850/U2A automotive MCU builds on key functions from Renesas’ RH850/Px Series for chassis control and RH850/Fx Series for body control to deliver improved performance.

This automotive-control MCU is equipped with up to four 400 megahertz (MHz) CPU cores in a dual-core lock-step structure. Each CPU core integrates a hardware-based virtualization-assisted function, which allows multiple software systems with varying ISO 26262 functional safety levels to operate independently without interference during high performance. It also reduces the virtualization overhead to maintain real-time execution. This enables users to integrate multiple ECU functions into a single ECU while maintaining safety, security, and real-time operation requirements.

The MCU includes security functions fulfilling EVITA Full for enhanced protection against cyber-attacks, enabling the device to support safe and rapid Full No-Wait Over-the-Air (OTA) software updates as security requirements evolve.

The RH850/U2A MCU is also equipped with an extensive set of networking interfaces, enabling the MCU to process the large amounts of sensor data being generated by multiple types of sensors in ADAS and autonomous driving functions. This allows customers to support future high-speed network functions and advanced communications throughput requirements.
