Working Principles

The CY8CMBR2044-24LKXIT operates based on the principle of capacitive touch sensing. It uses an array of electrodes to detect changes in capacitance caused by the presence of a conductive object (such as a finger). When a touch is detected, the IC processes the signal and provides the corresponding output.

The capacitive touch sensing technology relies on the fact that the human body acts as a capacitor. When a conductive object approaches the electrode, it changes the capacitance value, which is then measured by the IC to determine the touch input.
