Description

AW93303FDR, AW93303BFOR, AW93305DNR, AW93305BFOR, AW93307QNR, AW93310QNR and AW93312QNR are mul-channel capacitive sensors and mainly used for wear detection, touch key, linear slider, wheel slider, etc. Advanced self/mutual capacitance technology is adopted in AW933XX. With a high-resolution ADC and advanced digital signal processing (DSP) algorithm, the minimal capacitance that can be detected is as low as 1aF in typical application. AW933XX contains the I2C serial communication bus. Through I2C, Host can configure the chip to work. Upon event detection, the interrupt pin outputs asserts, enabling Host to receive the event information such as distance. A built-in ultra-low power MCU realizes AFE sampling control, signal filtering, RF noise suppression, adaptive temperature compensation, baseline tracking, touch/wearing status determination, etc. With the advanced DSP algorithm, AW933XX is able to track gradual environmental variations (such as temperature, humidity, etc.). AW933XX 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.
