New NEC 32-bit All Flash V850E/Ix4 Microcontrollers for Inverter Control

NEC Electronics America launched 15 new 32-bit All Flash V850E/Ix4 microcontrollers (MCU) for inverter- and motor-control applications. The V850E/Ix4 MCUs are ideal for air conditioners, solar-panel power systems, washing machines, dryers ,and factory-automation equipment. Samples of NEC Electronics’ new V850E/Ix4 microcontrollers are available now and volume production is scheduled to begin December 2009. Suggested pricing for 10,000-unit quantities ranges from $13.40 to $15.75 (US), depending on the package and peripheral options.

NEC V850E/Ix4 Microcontrollers Features

  • Enhanced inverter timer (2 units x 6 PWM outputs per unit) with up to 100-MHz operation
    Higher PWM drive frequencies and higher inverter/motor control loop frequencies enable highly energy-efficient, smart appliances and factory automation equipment.
  • Enhanced CPU operating frequency of 100 MHz, for finer-grained inverter control
    The new MCUs provide up to 1.5 times more performance than previous generations, in addition to offering better algorithm processing and finer-grained inverter control. Using a real-time operating system (RTOS), the new MCU devices can shorten the overall development process.
  • Up to 480 KB of embedded flash memory
    With up to 480 kilobytes (KB) of flash memory, the new 32-bit MCUs can be applied to systems that require large memory capacity for their programs, such as factory automation and air conditioning equipment.
  • On-chip USB function interface (V850E/IG4-H and V50E/IH4-H)
    NEC Electronics’ new V850E/IG4-H and V850E/IH4-H MCU devices include an on-chip USB function controller to facilitate the connection between peripheral systems and diagnostic interfaces for motor-control applications. Also provided on these devices is an external bus interface, and to support the USB interface and other data-transfer requirements, all the devices can support direct-memory access (DMA) channels.
  • Increased analog peripherals
    NEC Electronics’ new V850E/Ix4 MCUs integrate more analog peripherals, which are ideally suited for inverter control, including 20 ADC channels, six programmable op amps and 12 analog comparators, which offer a significant increase over the current generation of devices. By replacing discrete components with an integrated solution, manufacturers can dramatically reduce their bill of materials (BOM) costs and save space on system boards.

The new microcontrollers operate at 100 megahertz (MHz), offering increased performance over the previous generation MCUs (V850E/Ix3), and increased on-chip flash memory up to 480 kilobytes (KB), double the capacity of the V850E/Ix3 MCUs. Other peripheral expansion features include an on-chip USB function interface, 20 analog-to-digital converter (ADC) channels, additional operational amplifiers (op-amps) and analog comparators. These new All Flash MCUs are available in 100-pin (V850E/IG4) and 128-pin (V850E/IH4) packages.
