Dotted lines represent the internal connections on low pin count packages, joining the dedicated supply pins. 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.
