Renesas Electronics Corporation (TSE: 6723), a premier supplier of advanced semiconductor solutions, today announced the sample shipment of the industry’s first on-chip flash memory microcontroller (MCU) using a 28 nanometer (nm) process technology. To contribute to the realization of next-generation green cars and autonomous vehicles with higher efficiency and higher reliability, the revolutionary RH850/E2x Series MCU incorporates up to six 400 megahertz (MHz) CPU cores, which makes it the first on-chip flash memory automotive MCU to achieve the industry’s highest processing performance (Note 1) of 9600 MIPS (Note 2). The new MCU series also features a built-in flash memory of up to 16 megabytes (MB) as well as enhanced security functions and functional safety.
Under Renesas autonomy™, an open, innovative and trusted platform for assisted and automated driving, Renesas provides end-to-end solutions that advance the evolution of vehicles towards next-generation green cars, connected cars, and autonomous-driving vehicles. The 28nm-generation automotive control MCU is a new breakthrough product featuring next-generation technology for achieving vehicle control, which, together with the R-Car Family of systems-on-chip (SoCs) designed for cloud connectivity and sensing, constitute the two main pillars of the Renesas autonomy Platform. Car OEMs and Tier 1 manufacturers, such as Denso Corporation, have already started to adopt the new 28nm MCU, recognizing the MCU’s superior processing performance capable of developing next-generation fuel-efficient engines, as well as its unparalleled scalability as a platform that addresses the expected electronic control unit (ECU) integration to come from changes in automotive electrics/electronics (E/E) architecture.
Key features of the new RH850/E2x MCU Series
High processing performance to enable complex automotive control for green cars
To develop environmentally-friendly vehicles, next-generation fuel-efficient engines require high processing performance to allow the implementation of new fuel combustion systems. In addition, both high processing performance and high integration densities are required to achieve miniaturization and higher efficiency in the motors and inverters used in electric vehicles (EV) and plug-in hybrid electric vehicles (PHEV). The newly-developed 28nm-process flash memory MCU is the world’s first to achieve up to six 400 MHz CPU cores and 9600 MIPS processing capabilities. Compared to the earlier 40nm MCUs, the new RH850/E2x Series of MCUs also achieves approximately three times the performance at the same power level. The RH850/E2x realizes increased automotive control system integration by including enhanced sensor interfaces necessary for precise automotive control functions. Multi-core virtual environments and model-based development environments for the new MCUs will be available from Renesas partner companies.
