39 / 94 page  DS12991 Rev 1 39/94 STM32G030x6/x8 Electrical characteristics 80 5.1.6 Power supply scheme Figure 9. Power supply scheme Caution: Power supply pin pair (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. 5.1.7 Current consumption measurement Figure 10. Current consumption measurement scheme MSv47984V1 VDD Backup circuitry (LSE, RTC and backup registers) Kernel logic (CPU, digital and memories) IO logic IN OUT Regulator GPIOs 1.55 V to 3.6 V 1 x 100 nF + 1 x 4.7 μF VDD/VDDA VBAT VCORE Power switch VDDIO1 ADC VREF+ VREF- VSS/VSSA VREF 100 nF VSS VSSA VDDA VDD VREF+ MSv47901V1 IDDVBAT VBAT IDD VDD (VDDA) VBAT VDD/VDDA |
