STM8T143 block diagram
RC oscillator
The 1-MHz RC oscillator is an internal fixed frequency oscillator used to supply the clock to
the MCU system engine.
Voltage regulator
The voltage regulator has an internal comparison and feedback circuit that ensures the
V
capacitor.
MCU system engine
The MCU system engine controls the capacitive sensing engine and processes touch and
proximity detection signals.
REG
voltage is kept stable and constant. The regulator requires an external smoothing
