47 / 122 page  DS10009 Rev 7 47/122 STM32F071x8 STM32F071xB Electrical characteristics 96 6.1.6 Power supply scheme Figure 12. Power supply scheme 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.
