NEC Corporation has developed a 32-bit single-chip RISC microcontroller, the V850E/IA2 that has been optimised for inverter control.
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.
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 suitable for control system applications.
The device can also be used for 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 allows for the connection of 5 V peripheral devices and systems.
Production of 100,000 units per month for the mask ROM version (uPD703114GC ) will start in the second half of 2001, and will increase to 300,000 units per month from the first half of 2002.
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.
