The QuickSense™ C8051F99x family of ultra low power capacitive sensing MCUs provides the lowest power and highest sensitivity touch sensing solution for capacitive buttons, sliders, wheels and capacitive proximity sensing.
Architected from the popular C8051F9xx platform, the device combines the industry-leading low power technology of the C8051F9xx family with the fast and accurate capacitive sensing features of the QuickSense C8051F7xx/8xx families to address fast-growing capacitive touch applications.
C8051F99x touch sense MCUs feature sub micro amp (<1 μA) wake on touch average current consumption, 150 µA/MHz active mode and multiple sleep modes as low as 10 nA. With up to 14 capacitive sensing inputs and a patent-pending charge timing hardware capacitance to digital converter, the C8051F99x achieves unparalleled touch sensitivity, speed and ultra-low power in packages as small as a 3 mm x 3 mm QFN20.
Silicon Labs' QuickSense Studio offers a complete software environment to program, debug, and analyze capacitive touch sense, proximity sense, and ambient light sense solutions.
