DESCRIPTION

R8A66170 is a programmable 4-channel PWM generator produced using the silicon gate CMOS process.

R8A66170 can connect directly to the MPU data bus, and consists of a 16-bit prescaler and a PWM counter.

The pulse output includes three kinds of modes, allowing the independent control of each channel.

R8A66170 provides a software servo system in combination with the A-D function and the timer function of a one-chip

microcomputer. R8A66170 is a succession product of M66240.

FEATURES

• 4-channel individually controllable

• Built-in three kind of pulse output modes

• PWM repetitive frequency: 50 kHz (max.) (Mode 0, 8-bit resolution, fxin/255 at prescaler setting = 0)

• Output polarity selection possible

• External triggering possible

• The output after reset is in the high impedance state.

• Change of mode setting becomes effective after the current cycle.

• High output current : Io = ±24 mA (VCC = 5.0V)

• Wide operating power voltage range (VCC = 5.0V or 3.3V single power supply)

• Wide operating temperature range (Ta = -40~85 ºC)

APPLICATION

• Control of DC motors and stepping motors

• Control of Heater phase controllers

• Software servos for office automation equipment , and industrial equipment
