Figure 2. STM32H533xx power supply overview
During power-up and power-down phases, the following power sequence requirements
must be respected:
•
When VDD is below 1 V, other power supplies (VDDA, VDDIO2, VDDUSB) must remain
below VDD + 300 mV.
•
When VDD is above 1 V, all power supplies are independent.
•
During the power-down phase, VDD can temporarily become lower than other supplies
only if the energy provided to the MCU remains below 1 mJ. This allows external
decoupling capacitors to be discharged with different time constants during the power-
down transient phase.
