The QuickSense portfolio ofhuman interface (HI) products includes the Si1102 and Si1120 infrared andambient light sensors and the C8051F800 and F700 capacitive touch sensemicrocontrollers (MCUs). The combination of Silicon Labs' Si11xx proximitysensors and touch sense MCUs enables advanced human interfaces incorporating awide range of IR-based functions such as touchless switches and sliderscontrolled by gestures, proximity detection, motion detection, occupancy/usersensing and intrusion/tamper detection. Candidates for these HI applications includeportable consumer electronics, large appliances, personal medical devices,industrial controls, thermostats and security systems. TheQuickSense Si1102/Si1120 proximity and ambientlight sensors are the industry's fastest IR sensing solutions. Thesesensors use a patented single-pulse proximity measurement technique thatdramatically reduces system power. They provide extended range under a widevariety of lighting conditions, enabling developers to use of lower cost, lowerprofile LEDs. By pairing QuickSense sensors with F800 MCUs, developers candesign innovative touchless proximity sliders that fundamentally enhance the HIexperience through smart motion sensing. The QuickSense devices are supportedby the QuickSense Studio, an easy-to-use development environment that enablesdevelopers to design human interfaces without creating a single line of code. SiliconLabs is the first company to offer both IR sensing technology andhigh-performance touch-sense MCUs in the same portfolio. The QuickSense portfoliois breathing new life into infrared sensor applications by enabling intuitive"touchless" interfaces. Optimized for powerefficiency, the QuickSense Si1102/Si1120 proximity and ambientlight sensors enable touchless human interface sensing with superiordetection range. Based on a patent-pending capacitance-to-digitalconverter (CDC), the high-performance F800 MCUs offer the industry's fastestcapacitive touch sense capability. Offering a 40 microsecond acquisition time,the high-resolution CDC provides highly responsive touch sense functions thatreplace mechanical buttons, sliders and wheels.
