NEC Electronics Introduces 15 New 32-bit All FlashTM Microcontrollers for Inverter Control


Fine-Grained Inverter Control Enables Eco-Friendly Appliances

KAWASAKI, Japan, DUESSELDORF, Germany, SANTA CLARA, Calif. (U.S.A.), NEC Electronics today announced the availability of 15 new 32-bit All FlashTM V850 microcontrollers (MCU) for inverter control and motor control applications such as air conditioners, washing machines, dryers, factory automation (FA) equipment, and photovoltaic power systems. These products are in line with NEC Electronics’ strategy to develop semiconductor solutions to enable energy efficient products.
The new devices operate at 100 megahertz (MHz), offering increased performance over previous generation (V850E/Ix3), and increased on-chip flash memory up to 480 kilobytes (KB), double the capacity of the V850E/Ix3. Other peripheral expansion features include, an on-chip USB function interface, 20 analog-to-digital converter (ADC) channels, additional operational amplifiers (op-amps) and analog comparators. These new All Flash MCUs come in 100-pin (V850E/IG4) and 128-pin (V850E/IH4) packages.
Reduction of greenhouse gas (GHG) emissions has been one of the most pressing issues with which the world is tasked to resolve. Due to environmental regulations and the increasing importance of energy savings, demand for eco-conscious products, which make use of energy-efficient inverter control technology, is expected to grow even more. In addition, next-generation eco-friendly household systems such as photovoltaic power systems, electric heat pumps, and fuel-cell systems are attracting increasing attention. To address these growing demands, NEC Electronics developed the new MCUs with finer-grained inverter control functionalities compared to the previous generation V850E/Ix3 to enable the design of cost-effective and eco-friendly appliances.

Principal Features

* (1)Enhanced Inverter timer (2 units x 6 PWM outputs per unit) with up to 100 MHz operation for higher PWM drive frequencies and higher inverter/motor control loop frequencies enable highly energy-efficient, smart appliances and factory automation equipment.
* (2)Enhanced CPU operating frequency of 100 MHz, for finer-grained inverter control
The new MCUs provide up to 1.5 times more performance than previous generations, in addition to offering better algorithm processing and finer-grained inverter control. Using a real-time operating system (OS), the new MCU products can shorten the overall development process.
* (3)Up to 480 KB of embedded flash memory
With up to 480 kilobytes (KB) of flash memory, the new MCUs can be applied to systems that require large memory capacity for their programs, such as factory automation and air conditioning equipment.
* (4)On-chip USB function interface (V850E/IG4-H and V850E/IH4-H)
NEC Electronics’ new V850E/IG4-H and V850E/IH4-H MCU devices include an on-chip USB function controller to facilitate the connection between peripheral systems, and diagnostic interfaces for motor control applications. Also provided on these devices are an external bus interface, and to support the USB interface and other data-transfer requirements, all the devices can support seven DMA (direct memory access) channels.
* (5)Increased analog peripherals
All of NEC Electronics’ new V850E/Ix4 MCU devices integrate more analog peripherals, which are ideally suited for inverter control, including 20 ADC channels, 6 programmable op amps and 12 analog comparators, which offer a significant increase over the current generation of devices. By replacing discrete components with an integrated solution, manufacturers can dramatically reduce their bill of materials (BOM) costs and save space on system boards.

NEC Electronics believes these new MCUs will enable appliance manufacturers to reduce costs, and be faster to market with the development of eco-friendly household appliances and compact, low-cost factory automation equipment. The company plans to market them aggressively and continue to expand its lineup of high-performance inverter-control microcontrollers.

Pricing and Availability
Samples of NEC Electronics’ new MCUs are available now. Prices for samples of the new MCUs will vary depending on memory capacity. For example, the V850E/IH4, with 480 kilobytes of flash memory and 24 kilobytes of RAM will be priced at US$12 per unit. Mass production of the new devices is slated to begin in December 2009 and is expected to reach mass production of 2,000,000 units per month.
