During power up/down, the following power sequence requirements must be respected:
When VDD is below 1 V the other power supplies (VDDA, VDDUSB, VLCD), must remain
below VDD + 300 mV
When VDD is above 1 V all power supplies are independent.
Figure 6. Power-up/down sequence
1. VDDX refers to any power supply among VDDA, VDDUSB and VLCD.
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 the external decoupling
capacitors to be discharged with different time constants during the power down transient
phase.
Note:
VDD, VDDRF and VDDSMPS must be wired together, so they can follow the same voltage
sequence.
