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).
