Power supply scheme
Figure 8. Power supply scheme
Caution:
Power supply pin pair (VDD/VDDA and VSS/VSSA) 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.
