Description

AW93203CSR is an 3-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. AW93203CSR can recognize various gestures, such as single/double/triple click, short/long press ａｎｄ linear 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.
