Figure 16. Power supply scheme
Caution:
Each power supply pair (VDD/VSS, VDDA/VSSA etc.) must be decoupled with filtering ceramic
capacitors as shown above. These capacitors must be placed as close as possible to, or
below, the appropriate pins on the underside of the PCB to ensure the good functionality of
the device.
