13 / 73 page ![]() 3.8.4 Power supply supervisor The STM3WB09xE device embeds several power and voltage monitors: • Power-on-reset (POR): during the power-on, the device remains in reset mode if VDDIO is below a VPOR threshold (typically 1.65 V) • Power-down-reset (PDR): during power-down, the PDR puts the device under reset when the supply voltage (VDD) drops below the VPDR threshold (around 20 mV below VPOR). The PDR feature is always enabled • Programmable voltage detector (PVD): can be used to monitor the VDDIO (against a programmed threshold) or an external analog input signal. When the feature is enabled and the PVD measures a voltage below the comparator, an interrupt is generated (if unmasked) STM32WB09xE Functional overview DS14210 - Rev 6 page 13/73 |
