R8A66170SP

R8A66170DD/SP 4-CH 16-BIT PWM GENERATOR REJ03F0272-0100 Rev. 1.00 Apr.01.2008 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. FEATURES www.DataSheet4U.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 = 5.0V) 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 PIN CONFIGURATION (TOP VIEW) D0 D1 D2 Data bus inputs D3 D4 D5 D6 D7 Write control input Command/Data control input Chip select input WR C/D CS GND 1 2 3 4 5 6 7 8 9 10 ...
