AW9069 integrates 6-channel capacitive input detection and a smart SRAM-controlled 9-LED driver. By SRAM programming and register configuration, the touch and/or gesture could trigger pre-defined program to generate funny and complicated LED lighting effect as feedback without the aid of external MCU, so as to greatly enhance the interactive experience and reduce power consumption.
High performance sigma-delta capacitance digital conversion technology is adapted to detect input capacitance, and further touch and gesture decision is implemented by internal DSP.
9 LEDs are driven by independent constant current sinks with PWM duty adjustment. Each LED is selectable to be controlled by I2C interface directly or internal program in SRAM.
The device provides 400kHz fast I2C compatible interface with device address set by AD pin. The operating voltage range is 3.0V~4.5V.
