Renesas Electronics has released a new set of powerful MICROcontrollers, the RH850/U2B MCU, designed to meet the expanding need to combine multiple applications into a single chip and achieve a unified ECU for evolving electrical and electronic architectures. The Cross-domain MCU is a high performance, interference free, flexible and secure combination product developed for the stringent workload requirements of vehicle movement in applications such as hybrid ICE and xEV traction inverters, connection gateways, high-end zone control and domain control.
Customers can also combine these MCUS with r-Car S4 SoC devices for vehicle central gateway systems to build a scalable solution for THE E/E architecture. As a result, the company has expanded its cross-domain MCU portfolio from RH850/U2A MCU for body and chassis control systems to the high-performance RH850/U2B MCU.
Naoki Yoshida, Vice President, Digital Products Marketing, Renesas Automotive, said: "The future of automotive systems design lies in the vehicle-centric, area-oriented E/E architecture, which increases the need for automotive chips to meet the challenges these innovative architectures pose for future generations of vehicles." "The RH850/U2B MCU expands Renesas's family of cross-domain MCUS to provide customers with higher levels of performance, memory integration and hard-based support for new area and domain control applications, particularly powertrains and HEV/EV, while maintaining strict cost, safety, performance and performance. And the safety parameters that these vehicle systems need."
The 28nm MCU, created for regional and domain applications, builds on the key functions of the RH850/E2x series (for powertrain) and RH850/ C1M-AX series (for HEV/EV motor control), while adding some new enhancements. Including new accelerator IP, higher performance levels, and improved security. This combination allows users to combine multiple ECU functions into a single ECU while meeting stringent automotive safety, safety, and real-time operation requirements.
MCU's integrated VIRTUAL Machine Hypervisor hardware-based virtualization assistance provides multiple software systems with up to ISO26262 ASIL D functional security levels of functionality to operate independently without interference through high performance. It reduces the virtualization overhead of maintaining real-time execution. QoS provides delay monitoring and regulation for all bus hosts to ensure that minimum bandwidth is always available.
The MCU supports secure and fast completely no-wait OTA software updates, has dual banks of embedded flash, enables ECU updates and saves images while the MCU is in active mode and allows the ECU to run from the original code if a fault occurs. The integrated Motor Control Accelerator IP (EMU3S) works with multiple dedicated motor control timer structures such as GTM v4.1 and TSG3 to provide high speed rotation while significantly reducing CPU processing load. Dedicated DFP accelerator IP allows the CPU to offload a large number of computational operations for complex control.
