DESCRIPTION
FEATURES
APPLICATION
PIN CONFIGURATION (TOP VIEW)
R8A66173 has four 12-bit PWM (Pulse Width Modulation) circuits which are built by using the CMOS
process.
This IC controls PWM waveform by adjusting the “H” width according to serial data sent from MCU (Micro
Controller Unit) or other device. Each channel can be independently controlled.
High-resolution digital-analog (D-A) converter can be formed easily by connecting a low-pass filter (LPF)
circuit to the output pins of this circuit.
R8A66173 is the succession product of M66242.
● Built-in four 12-bit high-resolution PWM circuits
● Easy D-A conversion – Quick output waveform smoothing
● Serial data input
●“H” level width setting type
● 4 channels controlled independently
● All 4 channels reset by reset input (R), High-impedance status after reset
● All 4 channels controlled by output control input (OC)
● Settings take effect after ongoing cycle is completed
● Output : CMOS 3-state output
● Wide operating supply voltage range (Vcc=3.0~3.6V or Vcc=4.5~5.5V, single power supply)
● Wide operating temperature range: Ta=-40
● Analog signal control in televisions and audio systems
● Control of lamps, heaters and motors
● For software servo in home appliances and industrial machinery
Control by 1.22mV possible per step (V
Output current Io=±4mA (Vcc=5.0V range), Io=±2mA (Vcc=3.3V range)
