2008 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.

com • • • • • • • • • • 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.
