各位大神好,在看STM32的资料AN4488的时候,在3.1和3.2节,关于这个PDR_ON这个管脚的接法有特殊的规定,从字面意思理解是将PDR_ON管脚直接接地,使用NRST控制复位的这种做法只适用于F411等,二巷没有例举的F429等芯片就不能这么干,这是为什么呢?这两种芯片内部是有什么不同呢?或者说STM32F429的PDR_ON管脚可以直接接...

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 421,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,芯片开始正常...
