The component utilizes Capacitive sensing as the main sensing mechanism and its sensing capability is mainly dependent upon the values of the capacitors in the device. The component supports general-purpose input/output (GPIO), Pass/Fail comparator output, Analog voltage (A/V) output, and Interrupt output for detecting touch events. Its sensing circuit is also self-calibratable thus enabling a better sensing performance with very minimal calibration time.

The CY8C20140-SX2I component is mainly used in various interface applications such as gaming consoles, audio/video players and whiteboards. With its various features such as proximity detection, it can be used to detect and react to gestures such as swiping or tapping. The component\'s capabilities can also be used for motion-based applications to enable easy navigation or activation. Additionally, the component can be used to detect and interact with a variety of items such as water level indicators, pressure sensors, potentiometers and buttons.

The working principle of the CY8C20140-SX2I component is based on the physics of capacitance. The component measures the capacitance between two electrodes when there is a slight change in the dielectric material between them. This change can be caused by the presence of a finger or object touching the surface. The component then measures the change in capacitance and transmits the signal to an analyser which interprets the signal and triggers an appropriate response.

In addition, the component also features a Self-Calibration (SC) function. This function is used to recalibrate the component and ensure that the component is in optimum performance state. The component performs a brief self-calibration when it is initially powered up and then periodically when it detects any changes in the material between the electrodes. This ensures that the component can detect touch accurately and provide accurate readings.
