43.1.1.1. 上电复位与掉电复位(POR与PDR) 当检测到VDD的电压低于阈值VPOR及VPDR时,无需外部电路辅助,STM32芯片会自动保持在复位状态,防止因电压不足强行工作而带来严重的后果。见 图42_1,在刚开始电压低于VPOR时(约1.72V),STM32保持在上电复位状态(POR,Power On Reset),当VDD电压持续上升至大于VPOR时,芯...
2. Since the LQFP100 package does not feature the PDR_ON pin (tied internally to VDD), the minimum VDD value for this package is 1.71 V. 3. VDD/VDDA can drop down to 1.62 V by using an external power supervisor (see Section 3.5.2: Power supply supervisor) and connecting PDR_ON ...
