Renesas Electronics introduces 32-bit microcontrollers V8 All FlashTM50E2M/MN4

32-bit microcontrollers with flash memory that display the highest performance in the world ...

Provide higher performance while consuming less, all in a compact single-chip component targeting systems factory automation systems, industrial controls, printers and home appliances.

Renesas Electronics, the leader of advanced semiconductor solutions, today announced the availability of two new microcontrollers (MCUs) 32-bit All Flash ™ providing a processing performance of 1024 Dhrystone MIPS (million instructions per second, Note 1) at a clock frequency of 200 megahertz (MHz), ie the world's highest performance MCUs from the existing dual-core 32-bit embedded flash memory. These new MCUs have two CPU cores integrated, 64 kilobytes (KB) of RAM (random access memory) available for each core, 2 megabytes (MB) of flash memory and 64 KB of RAM additional system and are available in FBGA ( fine pitch ball grid array) of 304 pins. The new MCUs from Renesas Electronics have the following characteristics: (1) The integration of two 32-bit CPU cores V850E2M, (2) Up to 2 megabytes (MB) of flash memory, (3) The many peripheral functions such as interfaces USB, CAN and Ethernet as well as an increased number of channels for standard peripherals such as counters and serial interfaces. In addition, two single-core MCUs V850E2M with up to 1 MB of flash memory and one heart V850E2M board are also available.



Today, the systems in factories are becoming more accurate, rapid and complex to increase production capacity. Thus, the MCUs in the integrated automation systems for industries such as motion drive, servo drives or inverters should always offer higher performance levels. At the same time, it is also important to provide compact MCUs consume less energy to meet the growing demand for consumer products environmentally friendly. To meet these growing demands, Renesas Electronics has developed these new MCUs have the following key features.

Integration of two 32-bit CPU cores with the highest performance in the world by enriching the structure of its existing core CPU V850E2, Renesas Electronics has strengthened the parallel processing power required by more demanding applications and has successfully developed the core with V850E2M a treatment capacity of 2.56 Dhrystone MIPS per MHz per core. This value corresponds to a gain of a factor of 1.4 over the previous V850E2 heart of the business. By using two cores V850E2M, system designers can use the highest processing performance in the world with 1024 DMIPS for a clock frequency of 200 MHz while maintaining low power consumption of 0.88 milliwatts (mW) per Dhrystone MIPS. The single-core version is 60% less energy consuming compared to dual core. In addition, the CPU core V850E2M strengthened its calculation unit in Floating Point Unit (FPU) to enable greater accuracy and cover a greater range in floating point numbers. This feature is particularly suited to information systems that require the processing of data at high speed or complex algorithmic calculations.

Flash memory high speed, high capacity The new MCUs boarded up to 2 MB of flash memory produced by the technological process high-speed 90-nanometer (nm). The MCUs also include V850E2M/MN4 memory cache for each CPU core, which allows access to the instructions in one cycle at 200 MHz, thus improving overall system speed.

In addition to extensive peripheral functions CAN interfaces, USB (Host and Function) and Ethernet, the new MCUs provide a wide range of peripheral functions, such as a large number of channels for counters and multiple serial interfaces. This rich array of peripheral functions enables system designers to reduce the number of external components to the chip, saving board space and achieve compact systems at reduced cost. Two external memory bus are also available to facilitate the development process for ASICs and external memory, contributing to higher performance.

Complete development environment will provide software developers Electronics Renesas development environment optimized for multicore and multi-processing support asymmetric (AMP: asymmetric multiprocessing). In addition, the solution Prism development environment and testing multi-core software that allows engineers to programmers to easily evaluate and use the full potential of multi-core processors without having to modify the source code or make Additional simulations, is also available from CriticalBlue, a provider of analysis software embedded multi-core.

System designers can choose their MCUs, either single-core or dual-core, each MCU-based CPU core from Renesas V850E2M Electronics is a core to the edge of technology with very high processing capacity. Electronics for Renesas, these new MCUs will contribute to the development of competitive systems for applications in factory automation, industrial control systems, printers and home appliances.
