85 / 135 page  DS12232 Rev 4 85/135 STM32G071x8/xB Electrical characteristics 107 Figure 23. Recommended NRST pin protection 1. The reset network protects the device against parasitic resets. 2. The user must ensure that the level on the NRST pin can go below the VIL(NRST) max level specified in Table 54: NRST pin characteristics. Otherwise the reset will not be taken into account by the device. 3. The external capacitor on NRST must be placed as close as possible to the device. 5.3.16 Analog switch booster 5.3.17 Analog-to-digital converter characteristics Unless otherwise specified, the parameters given in Table 56 are preliminary values derived from tests performed under ambient temperature, fPCLK frequency and VDDA supply voltage conditions summarized in Table 21: General operating conditions. Note: It is recommended to perform a calibration after each power-up. MS19878V3 RPU VDD Internal reset External reset circuit (1) NRST (2) Filter 0.1 μF Table 55.
