Renesas autonomyTM is an open, innovative and reliable development platform for Renesas Electronics for Smart Assisted Driving and Automated Driving Development. Through this platform, Renesas Electronics is the next generation of eco-friendly cars for the automotive industry, Netlink Automotive, and Autonomous Vehicles. The evolution provides an end-to-end solution. The 28nm process vehicle control MCU is a breakthrough product designed for cloud service interconnection and environmental awareness. It possesses the advanced technology required by the next-generation automotive control system, and The Renesas R-Car System-on-Chip (SoC) constitutes the main product pillar of the Renesas autonomy platform. First-tier suppliers such as automotive manufacturers and Denso have already adopted the 28nm MCU product and have unanimously endorsed the superior handling of the MCU. Performance helps develop the next generation of energy-efficient engines. At the same time, the MCU has unprecedented scalability, enabling it to serve as a platform for the evolution of future automotive electronics/electrical architectures, and the electronic control unit (ECU) brought about by this change. ) Integration requirements.
Major Performance of the New RH850/E2x Series MCUs
(1) Superior handling performance for complex vehicle control required for environmentally friendly vehicles. To develop environmentally friendly vehicles and next-generation energy-efficient engines, superior handling performance is required to support new fuel system designs. In addition, for electric vehicles High-efficiency engines and converters for miniaturization of hybrid cars, excellent processing performance and high integration are indispensable conditions. The newly released 28nm process flash MCU is the world's first to have up to 6 400MHz processing cores and 9600MIPS Instruction speed microcontrollers. Compared to earlier 40nm MCUs, the new RH850/E2x family of MCUs can achieve 3X processing performance at the same power level. The RH850/E2x family has built-in enhanced sensor interfaces for automotive control. The integration of the system provides better precision control functions. For the new MCU, Renesas Electronics partners will also provide a multi-core virtual environment and a model-based development environment.
(2) The large-capacity flash memory used in the car network supports advanced OTA software updates. The need to wirelessly download OTA functions has led to an increase in the built-in flash memory capacity. The OTA function can automatically update the vehicle's electronic control unit (ECU) through a wireless network. ) Firmware to improve and enhance the security of the system. The RH850/E2x series integrates 16MB of flash ROM and supports the option to update only specific areas of the flash memory according to user requirements. RH850/E2x enhanced serial communication interface configuration, Supports up to 10 channels of CANFD interface and 1 channel of Ethernet interface. Supports Evita Medium's hardware security features to enable microcontrollers to perform OTA software updates quickly and reliably.
(3) Enhanced functional safety for self-driving cars. To achieve the highest level ASIL-D standard in ISO26262 automotive electrical/electrical system functional safety standards, the RH850/E2x series adopts a dual-core lock-step architecture, guaranteeing two The processing results of the processing core are exactly the same. The RH850/E2x can provide up to 4 interlocked dual cores and feature improved functional safety of many hardware. In life-critical applications, these functions detect problems immediately when a fault occurs. And always maintain the security of the system. Renesas Electronics will provide security analysis tools to help implement a variety of security systems suitable for different application scenarios.
Following the announcement of the development of the 28nm embedded flash memory in February 2015, Renesas Electronics announced in September 2016 that it will cooperate with TSMC to produce 28nm MCUs. The world’s first 28nm embedded flash MCU will be introduced to the market today and will become Renesas. Another important milestone for electronics. Renesas Electronics has verified the application of fin-shaped MONOS flash memory technology in 16/14nm and next-generation MCU products.
To ensure the scalability of the RH850/E2x family, Renesas Electronics announced two 40nm MCUs in addition to the 28nm flash MCU, with points (1) and (3) in the above product features. Using 28nm technology and Samples of RH850/E2x series MCUs manufactured on the 40nm process have been available since March 2018.
