GENERAL DESCRIPTION

The ML66517 family of highly functional CMOS 16-bit single chip microcontrollers utilizes the nX-8/500S, Oki's

proprietary CPU core.

Each device includes capture input with an internal digital filter, 10-bit A/D converter, a number of timers, and

dedicated 3-phase PWM (6 outputs) function capable of generating and controlling of AC/DC motor driving

waveforms.

By means of the internal dedicated function for motor control, this general-purpose microcontroller is optimally

suited for DC and AC motor control applications for energy saving. And the internal hardware multiplier allows

high-speed arithmetic operations to be executed. And also the internal clock multiplication circuit can reduce the

source frequency noise so that high-speed operations can be performed.

The flash ROM versions (ML66Q517 and ML66Q515) programmable with a single 5V power supply are also

included in the family. These versions are easily adaptable to quick specification changes and to new product

versions.

APPLICATIONS

Air conditioner or inverter control

Motor control for FA equipment
