KAWASAKI, Japan, SANTA CLARA, Calif. and DUSSELDORF, Germany, September 15, 2003 -
NEC Electronics Corporation and its subsidiaries in the United States and Europe, NEC Electronics America, Inc. and NEC Electronics (Europe) GmbH, today announced the V850E/IA3TM and V850E/IA4TM microcontroller units (MCUs) for motor and inverter control systems in electronic home appliances. Designed for one- and two-motor control in appliances such as air conditioners, washers, dryers and refrigerators, the V850E/IA3 and V850E/IA4 achieve the industry's highest speed of 64 MHz and 82 (Dhrystone 1.1) MIPS. As members of NEC Electronics' V850TM series, over 230,000,000 of which have already been shipped, these new MCUs are ideal for high-end application-specific standard products (ASSPs) that require high performance and real-time control.
The latest additions to NEC Electronics' offering of motor and inverter control solutions, the V850E/IA3 and V850E/IA4 MCUs feature a 60 percent improvement in instruction speed over previous members of the V850E/IAxTM family. With this significant performance increase, 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 128 to 256 KB. Both the 256 KB flash ROM and the 128 KB mask ROM are available for the V850E/IA3 device. The V850E/IA4 MCU has an additional 256 KB of mask ROM available. RAM size has also been increased from 6 to 12 KB.
To further improve motor and inverter control functionality, pulse-width modulation (PWM) timers were embedded, as were two high-speed 10-bit A/D converters with 2-microsecond conversion speed and a delta-sigma A/D converter. An operational amplifier (op-amp) and comparator also have been added on-chip to reduce system costs.
"The call for highly precise motor and inverter control in electronic home appliances is increasing, as lower noise, richer functions and greater cost reductions are continuously being pursued, and solutions that lower energy and reduce carbon dioxide (CO2) emissions are being required," said Yoshihiko Miura, general manager, 2nd Solutions Division, NEC Electronics Corporation. "To respond to this market demand, we have developed these new MCUs with the fastest CPU on the market and rich peripheral functions to reduce costs and shorten development turnaround times for a wide range of home electronics applications."
The company offers two types of emulators for the V850E/IA3 and V850E/IA4. The first is an N-wire card, an inexpensive card-type on-chip debugging emulator; the other is a full-function in-circuit emulator (ICE) supporting 64-MHz operation. Both are equipped with a function to prevent the circuit burnout inherent in the debugging of motor and inverter systems.
Pricing and Availability
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 Q4 2004.
