Power supply scheme
Figure 13. Power supply scheme
1. N corresponds to the number of VDD pins available on the package.
2. A tolerance of +/- 20% is acceptable on decoupling capacitors.
3. VCAPDSI pin must be externally connected to VDD12DSI pin.
Caution:
Each power supply pair (VDD/VSS, VDDA/VSSA ...) must be decoupled with filtering ceramic
capacitors as shown above. These capacitors must be placed as close as possible to, or
