53 / 110 page  DS13259 Rev 2 53/110 STM32WB10CC Electrical characteristics 102 6.1.6 Power supply scheme Figure 10. Power supply scheme 1. The value of L1 depends upon the frequency, as indicated in Table 4: Typical external components. Caution: Each power supply pair (e.g. VDD / VSS, VDDRF / VSSRF) must be decoupled with filtering ceramic capacitors as shown in Figure 10. 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.
