Power supply scheme

Figure 11. Power supply scheme

Caution:

Each power supply pair (VDD/VSS, VDDCORE/VSS, VDDA/VSSA ...) must be decoupled with

filtering ceramic capacitors. These capacitors must be placed as close as possible to, or

below, the appropriate pins on the underside of the PCB to ensure good operation of the

device. It is not recommended to remove filtering capacitors to reduce PCB size or cost.

This might cause incorrect operation of the device.
