New 8- and 32-bit MCUs Feature 180-Degree Control and Up to 128 KB of Embedded Flash Memory
"The demand for home appliances whose power consumption and electricity costs are low is steadily increasing," said Bart Ladd, general manager, standard solutions strategic business unit, NEC Electronics America. "NEC Electronics' 8- and 32-bit motor control solutions are designed to help system developers meet this demand, and are the first products in a line the company plans to expand in the future."
Based on NEC Electronics' high-performance V850ES(TM) CPU, the 32-bit V850ES/IE2 devices have flash memory capacities of 64 and 128 kilobytes (KB) and deliver precise motor control functions that help to limit vibration and noise, reduce power consumption, lower electricity costs for consumers and minimize environmental impact.
The 8-bit uPD78F0711 and uPD78F0712 All Flash MCUs are based on NEC Electronics' efficient and economical 78K0 CPU core, and offer flash memory capacities of 8 and 16 KB as well as packages with half the pins of the company's previous-generation 8-bit uPD78F0714 MCU.
All of the new 8- and 32-bit MCUs operate at speeds up to 20 megahertz (MHz) at 4.0 to 5.5 volts (V) and incorporate a variety of safety features necessary for motor control applications, including a power-on-clear (POC) reset circuit, low-voltage indicator, watchdog timer, clock monitor and external hardware trigger for controlled system shutdown and recovery in the event of a power failure. The devices also include hardware that has been optimized for inverter control, such as multi-function timers, high-speed A/D converters and overcurrent protection circuits.
In addition to the standard 120-degree control method, the devices offer 180-degree control, which has been gaining popularity in recent years because of its greater precision and reduced torque ripple. Separation of system control functions and optimization of MCU design specifically for motor control applications enhances the performance of these devices and contributes to the development of household appliances that consume less power and help lower utility bills.
NEC Electronics' V850ES/IE2, uPD78F0711 and uPD78F0712 MCUs provide embedded flash memory based on the SuperFlash(R) technology licensed from Silicon Storage Technology, Inc., which allows system developers to program software even after production, thereby reducing development times, and to adjust software in the field to accommodate product specification changes. Moreover, the new devices are compatible with legacy products, enabling efficient use and reuse of existing legacy software resources. In addition, the software is compatible with similar mask ROM devices from previous generations, allowing designers to develop systems using existing software resources.
Development tools for these products include NEC Electronics America's standard hardware and software tools, as well as its newly released, low-cost motor control evaluation kit.
