These microcontrollers incorporate an inverter control function for
sensorless/sensor-equipped 3-phase DC and AC motors and a sine
wave drive circuit for supporting high reliability and high temperature
operation. The sine wave drive circuit enables easy sine wave drive
suited to high efficiency and low noise.
