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
www.DataSheet4U.c4o-mchannel 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
