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

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 filters
The device has two channels of capture inputs with 3/4 digital filters. The device is best suited to event interval
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 with a single power supply
In addition to the mask ROM versions, the family includes the versions (ML66Q517 and ML66Q515) with 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 scans 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 complete flexibility in circuit board layout and system design. These
programmable pull-up resistors are available for all I/O pins not already assigned specific functions (such as the
oscillator connection pins).

Definition of Terminology

1. Resolution

Resolution is the value of minimum discernible analog input.
With 10 bits, since 2

= 1024, resolution of (V

REF

AGND)

1024 is possible.

2. Linearity error

Linearity error is the difference between ideal conversion characteristics and actual conversion characteristics
of a 10-bit A/D converter (not including quantization error).
Ideal conversion characteristics can be obtained by dividing the voltage between V

REF

and AGND into 1024

equal steps.

3. Differential linearity error

Differential linearity error indicates the smoothness of conversion characteristics. Ideally, the range of analog
input voltage that corresponds to 1 converted bit of digital output is 1LSB = (V

REF

AGND)

1024.

Differential error is the difference between this ideal bit size and bit size of an arbitrary point in the conversion
range.

4. Zero scale error

Zero scale error is the difference between ideal conversion characteristics and actual conversion characteristics
at the point where the digital output changes from 000H to 001H.

5. Full-scale error

Full-scale error is the difference between ideal conversion characteristics and actual conversion characteristics
at the point where the digital output changes from 3FEH to 3FFH.

Notes for Mounting the Surface Mount Type Packages

The surface mount type packages are very susceptible to heat in reflow mounting and humidity
absorbed in storage.
Therefore, before you perform reflow mounting, contact Oki's responsible sales person for the product
name, package name, pin number, package code and desired mounting conditions (reflow method,
temperature and times).
