TOKYO January 23rd, 2001 - NEC Corporation (NEC) (NASDAQ: NIPNY) (FTSE: 6701q.l) (TSE: 6701) has developed a 32-bit single-chip RISC microcontroller, the V850E/IA2, optimized for inverter control applications to meet recent demands for lower power consumption in consumer appliances and for a finer degree of control in industrial applications.
Sample shipments of the application specific standard product (ASSP), the second iteration of the V850E/IAx series, are planned to begin with the flash memory version (uPD70F3114GC) from February 2001.
The V850E/IA2 is an ASSP (Application Specific Standard Product) for inverter control that incorporates a 32-bit RISC core, the V805E1. NEC plans to maintain its position as a leading provider of solutions in the inverter control field by enhancing this series with high-speed high-performance versions featuring ultra-low power consumption and low noise, as well as expanding its ASSP lineup and application range.
Operating at 40 MHz, the V850E1 32-bit RISC CPU core provides 50 MIPS performance for high-speed execution of 32-bit multiply, saturated operation, bit manipulation, and other instructions, making it highly suitable for control system applications. The device also realizes precision inverter control through the combination of a 2-channel 3-phase sine-wave PWM timer that enables 2-system inverter drive output, and functions such as encoder input and an internal 2-channel 10-bit A/D converter. The additional incorporation of a regulator for configuring 5 V single-power-supply systems provides the opportunity for easy connection of conventional 5 V peripheral devices and systems.
Production is expected to amount to 100,000 units per month for the mask ROM version (uPD703114GC ) starting from the second half of 2001, increasing to 300,000 units per month from the first half of 2002.
Background
Inverter control offers energy efficient motor driver operation for consumer
appliances and fixed or adjustable speed control that can negate effects
from torque variation for industrial electronic applications, and is becoming
increasingly widespread.
Demands are therefore mounting for inverter control microcontrollers that can provide the performance and specifications required to exploit these features, specifically the ability to compare the motor drive pattern currently being output with the actual number of revolutions measured in the motor in order to compile the next drive pattern. Consequently, because inverter microcontrollers must have a high-speed calculation function in addition to peripheral functions, they have evolved from 8 bits to 16 bits, and then to 32 bits, with a shift in architecture from CISC (Complex Instruction Set Computer) to RISC (Reduced Instruction Set Computer).
The devices announced today are V850E Family ASSPs for inverter control applications developed by NEC to meet these recent demands. The V850E/IA2 follows the V850E/IA1 launched in 1999 and is targeted at consumer electronics applications such as inverter air conditioners, refrigerators, and washing machines, and industrial applications such as general-purpose inverters, AC servo motors, and UPS.
NEC plans to maintain its position as a leading provider of solutions in the inverter control field by enhancing this series with high-speed high-performance versions featuring ultra-low power consumption and low noise, as well as expanding its ASSP lineup and application range.
