Renesas Electronics Corporation today announced the world’s first (Note 1) microcontroller (MCU) with embedded flash that integrates a hardware-based virtualization -assisted function while maintaining the fast, real-time performance of the RH850 products. This hardware-based virtualization assist technology can support up to ASIL D (Note 2) level of functional safety, providing greater levels of system integration.
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 a 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 MCU builds on key functions from Renesas’ RH850/Px Series for chassis control and RH850/Fx Series for body control to deliver improved performance and implement a virtualization-assisted function to support operation in chassis/safety, body, domain control and low-end/mid-range gateway applications. To support the ASIL D level required for chassis/safety applications, the hardware-based virtualization assist technology allows customers to implement multiple software with different functional safety levels on the RH850/U2A MCU and run concurrently without interference, while maintaining the real-time performance required to control the vehicles.
“The evolution of new E/E Architecture is driving the trend toward single ECUs that support multiple ECU functions for high-performance devices that can operate across multiple application areas,” said Naoki Yoshida, Vice President, Renesas’ Automotive Technical Customer Engagement Business Division. “Starting with the RH850/U2A, Renesas’ new series of cross-domain MCUs increases development efficiency and reduces development time to accelerate connected and autonomous vehicle development strategies, and we are excited to lead the charge with virtualization and ASIL D support.”
