82 / 236 page  Electrical characteristics STM32G474xB STM32G474xC STM32G474xE 82/236 DS12288 Rev 4 5.1.6 Power supply scheme Figure 16. 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.
