NEC Electronics has made available 15 new 32bit All Flash V850 MCUs for inverter control and motor control applications such as air conditioners, washing machines, dryers, factory automation 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 100MHz, offering increased performance over previous generation (V850E/Ix3) and increased on-chip flash memory up to 480Kbytes, double the capacity of the V850E/Ix3. Other peripheral expansion features include an on-chip USB function interface, 20 ADC channels, additional 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 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 with the previous generation V850E/Ix3 to enable the design of cost-effective and eco-friendly appliances.

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.

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 480Kbytes of flash memory and 24Kbytes of RAM will be priced at $12 per unit. Mass production of the new devices is slated to begin in December 2009.
