Figure 1. Stm32C0 Series Power Supply - ST STM32C0 Series Getting Started

+ 1 x 4.7 µF
Note: Power supply pin pairs (VDD/VDDA and VSS/VSSA) 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.
