Internal sampling capacitor
To reduce the application cost and increase the device flexibitlity, the STM8T143 features
several internal sampling capacitors to fit a wide range of applications.
Electrode parasitic capacitance compensation (EPCC)
The implementation of an electrode pad in a system always induces parasitic capacitances
through tracks and surrounding components.The electrode parasitic capacitance is the
residual capacitance between electrode and ground when no finger is present.
The EPCC is an internal hardware circuitry that compensates part of the electrode parasitic
capacitance to improve the capacitive sensing channel sensitivity.
