We are using STM32H753 controller In Power off condition we checked VBAT discharge current in STM32H753BIT6 .The discharge current is pulsating from 4uA to 28uA.We enabled only RTC peripheral.We are not sure why the behaviour is like this

We are using STM32F767BGT6 controller and S25FL128LAGMFI010 NOR Flash .I want to do Timing analysis between this two ic's . Below is the formula used for calculating setup margin and hold margin.SETUP MARGIN =CLOCK PERIOD-TCO(MAX)-TSU,HOLD MARGIN=TCO...
