42 / 93 page ![]() Electrical characteristics STM32F030x4/x6/x8/xC 42/93 DS9773 Rev 4 6.1.6 Power supply scheme Figure 13. 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. 6.1.7 Current consumption measurement Figure 14.
