NEC Electronics Corp. (Santa Clara, CA) and its subsidiaries in the US and Europe, NEC Electronics America Inc. and NEC Electronics GmbH, announced the V850E/IA3™ and V850E/IA4™ microcontroller units (MCUs) for motor and inverter control systems in electronic home appliances. As members of NEC Electronics' V850™ Series, the new MCUs are suitable for high-end, application-specific, standard products (ASSPs) that require high performance and real-time control.
Designed for one-motor and two-motor control in appliances such as air conditioners, washers, dryers and refrigerators, the V850E/IA3 and V850E/IA4 achieve a speed of 64MHz and 82MIPS.
The V850E/IA3 and V850E/IA4 MCUs feature a 60% improvement in instruction speed over previous members of the V850E/IAx™ family. The new devices allow designers to generate precise motor control in load change, rotation speed change and parallel control operations, while avoiding harmonic problems. In addition, the built-in ROM has been expanded from 128KB to 256KB. Both the 256KB flash ROM and the 128KB mask ROM are available for the V850E/IA3 device. The V850E/IA4 MCU has an additional 256KB of mask ROM available. RAM size has also been increased from 6KB to 12KB.
Engineering samples will be available October 2003 for both devices. Samples are priced at $20 each for the V850E/IA3 and $25 each for the V850E/IA4. Mass production for both is scheduled to start July 2004 and expected to reach a total of 200,000 units per month in fiscal year 2005. The card-type, on-chip, debugging emulator is available now, and the full-function ICE is scheduled for availability in the fourth quarter of 2004.
