AW93208GQNR中文资料8-Channel Capacitive Wear Detection ａｎｄ Touch Key Controller.数据手册Awinic规格书

描述 Description

AW93208GQNR is an 8-channel capacitive proximity and touch controller mainly used for wear detection, touch key, linear slider, wheel slider, etc. The chip can realize accurate position detection for lamp dimming, volume adjustment, etc.AW93208GQNR can recognize various gestures, such as single/double/triple click, short/long press, linear slide and wheel slide with the high-resolution capacitive sensing. The chip integrates mutual capacitive technology and dedicated algorithm, which greatly improve the waterproof performance for touch key.The built-in ultra-low-power MCU and 16KB flash realize AFE sampling control, signal filtering, RF noise suppression, adaptive temperature compensation, baseline tracking, touch/wearing status determination, etc. The chip can flexibly customize the program and support online upgrade function.
