AW9119QNR中文资料1-Key Capacitive Touch Controller Integrated with 9-LED Driver数据手册Awinic规格书

描述 Description

AW9119 integrates 1 capacitive sensor and aSRAM program-controlled 9 LED driver. By specialprogramming and register configuring, the touch orgesture can trigger predefined lighting program togenerate funny and complicated LED effect,without the aid of external MCU.The  capacitive  sensor  takes  advantage  ofadvanced  Sigma-delta  capacitance  digitalconversion technology to achieve high sensitivityand anti-noise capacitance detection. With internalDSP algorithm, the touch and gesture event can bedetected and reported in status register andexternal interrupt pin.9 LED driver uses common anode current sourceand PWM dimming. Each LED is 8-level drivercurrent selectable with dimming independentlycontrolled  by  external  MCU  or  internal256word*16bit SRAM program.
