Caution:

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

pins.

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.
