Smart 27 LED Driving SoC with Audio Synchronization

AW22127 is a smart LED driving SoC with audio synchronization, integrated with MCU, Flash ROM, SRAM, ADC, PGA, and LED driver circuit. All lighting effect is implemented by pre-loaded firmware designed for specific application. There are 9 constant current sinks (LED1~9) and 3 current switch (COM1~3) capable of driving up to 27 LEDs or 9 RGB LEDs in matrix display mode. Each LED has 256 current steps for brightness or color-mixing, 12-bit PWM level for dimming. When the max output current is 75mA with 1/3 cycle rate, 25mA average current is available for each LED. Additionally, parameter configurable PGA, ADC, digital filters provide flexible sampling and process function for audio input. Unusually brilliant audio sync lighting effects could be achieved by sophisticated firmware design. AW22127 is available in QFN4mmX4mm-24L package, it operates from 2.7V to 5.5V over -40℃ to +85℃.
