Renesas Electronics Expands Lineup of 28nm Cross-Domain Automotive Microcontrollers

     Renesas Electronics Group, a global supplier of semiconductor solutions, announced the launch of a new family of powerful microcontrollers (MCUs), the RH850/U2B, that integrates multiple applications into a single chip and provides the E) The architecture realizes a unified electronic control unit (ECU) to meet the growing demands of the market. The RH850/U2B cross-domain MCU combines high performance, flexibility, noise immunity and security, and is designed to meet the demanding workload requirements of vehicles in operation, including hybrid ICE and xEV motor inverters, Applications such as high-end area control, Internet gateway and domain control.

     As a result, Renesas has expanded its cross-domain MCU product lineup from the RH850/U2A for body and chassis control systems to the high-performance RH850/U2B. Customers can also combine it with Renesas' R-Car S4 SoC for automotive central gateway systems to create scalable solutions for E/E architectures.

     Naoki Yoshida, Vice President of Renesas Electronics Automotive Digital Product Marketing Division, said: "The future of automotive system design lies in the vehicle-centric, domain-oriented E/E architecture; it also increases the demand for automotive chips to cope with These innovative architectures pose challenges for next-generation vehicles. The RH850/U2B expands the Renesas cross-domain MCU product family, bringing customers higher levels of performance, memory integration, and hardware-based support for new regions and regions Control applications, especially for powertrains and HEV/EVs, while meeting the stringent requirements required by vehicle systems such as cost, safety and encryption.”

     The 28nm RH850/U2B is designed for regional and domain applications, building on the key features of Renesas' RH850/E2x series for powertrain and RH850/C1M-Ax series for HEV/EV motor control, adding New accelerator IP, improved performance and security. These improvements enable users to integrate multiple ECU functions into a single ECU while meeting stringent automotive-grade security, encryption and real-time operability requirements.

     The Hypervisor based on the MCU hardware virtualization mechanism allows multiple software systems with functional safety levels up to ISO26262 ASIL D to run independently without interference under high performance conditions, reducing the time required for virtualization to ensure real-time processing. QoS provides latency monitoring and regulation for all bus masters to ensure the minimum bandwidth available at all times. The RH850/U2B supports secure and fast zero-wait OTA software updates; the use of dual-zone embedded flash memory allows the ECU to update and save images while the MCU is in active mode, and enables the ECU to run from source code in the event of a failure. The integrated Motor Control Accelerator IP (EMU3S) works in conjunction with multiple dedicated motor control timer structures such as GTM v4.1 and TSG3 to achieve high-speed rotation while significantly reducing CPU processing load. Dedicated Data Flow Processor (DFP) accelerator IP enables the CPU to offload computationally heavy operations for complex control.
