121 / 245 page ![]() DS12500 Rev 1 121/245 STM32MP151A Electrical characteristics 228 6.1.6 Power supply scheme Figure 11. Power supply scheme Caution: Each power supply pair (VDD/VSS, VDDCORE/VSS, VDDA/VSSA ...) must be decoupled with filtering ceramic capacitors. These capacitors must be placed as close as possible to, or below, the appropriate pins on the underside of the PCB to ensure good operation of the device. It is not recommended to remove filtering capacitors to reduce PCB size or cost. This might cause incorrect operation of the device.
