2008 DESCRIPTION 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.
