GENERAL DESCRIPTION

The ML66517 family of highly function al CMOS 16-bit single chip m icrocontrollers utilizes the nX-8/500S, Ok i'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

SPECIAL FEATURES

1. High-performance CPU

The family includes the high-performance CPU, powerful bit manipulation instruction set, full symmetrical
addressing mode, and ROM WINDOW function, and also provides the best optimized C compiler support.

2. 3-phase PWM circuit for generating motor drive waveforms

The device includes a 16-bit three-phase PWM (six outputs) circuit designed specifically for generating AC
three-phase motor or DC three-phase brushless motor drive waveforms. PWM and level outputs can be switched
by compare and match circuitry and software, and the compare and match circuitry can switch the outputs in real
time.
The device has circuitry to fix the three-phase outputs at an inactive level by inputting malfunction signals from a
motor at the specific pin.

3. Capture inputs with digital filter f ilt ers

The device has two channels of capt ure inputs with 3/4 digital filters. T he device is best suited to event inter val
measurement, pulse width measurement, etc. in a high noise environment such as motor control. An optimum
filter can be selected according to noise width since a sampling interval of an input signal can be selected. A digital
filter OFF mode can also be selected.

4. High-speed multiplier

The device includes a dedicated high-speed multiplier.
The calculation time, 16 bits × 16 bits = 32 bits, is 200 ns (f = 25 MHz).

5. Clock multiplication circuit

The device includes a clock multiplication circuit in which the clock can be selected as a source clock (PLL OFF),
1 × clock, 2 × clock, or 4 × clock.
Therefore, the use of a low frequency oscillator (external clock) allows the device to internally operate at a high
speed, which achieves noise reduction and lower power consumption.

6. Flash memory version programmable wit h a single power supply

In addition to the mask ROM versions, the family includes the vers ions (ML 66Q517 and ML 66Q515) w ith 64 KB
flash memory that can be programmed with a single 5 V supply.

7. A high-precision A/D converter

The device has a high precision 10-bit A/D converter with eight channels.
An independent result register for each channel provides easy accessibility by software.
The A/D converter is activated in a channel select mode, and automatic conversion is also implemented in a scan
mode which sc ans from any designated channel to the last channel (ch 7).

8. Programmable pull-up resistors

Building the pull-up resistors into the chip contributes to overall design compactness. Making them
programmable on a per-bit basis allows co mplete flexibility in circuit board layout and system design. T hese
programmable pull-up resistors are available for all I/O pins not already assigned specific functions (such as the
oscillator connection pins).
