1. Once nRST is released functionality is guaranteed down to VBOR falling edge max.

2. Min VDD is 2.25 V when REG1V8 is used BYPASS_REG1V8 = 0.

3. Should be connected to same power supply voltage as VDD.

4. It is recommended to connect VDD_PLL and VDD_PLL2 to same power supply as VDD.

5. 1.25 V is the max allowed voltage, however LPLV-Stop mode is only relevant for VDDCORE up to 0.95 V. In LPLV-Stop

mode, if VDDQ_DDR is not shutdown, to avoid overconsumption on VDDQ_DDR, the DDR memory must be put in

SelfRefresh and DDR PHY must be set in retention mode (setting bit DDRRETEN: DDR retention enable of PWR control

6. DAC cannot be used with VREF below 1.8 V.

7. ADC cannot be used with VREF below 2 V and VDDA above 2 V.

8. Depending on package selected, either VDD3V3_USBFS and VDD3V3_USBHS or only VDD3V3_USB are available.

9. For operation with voltage higher than Min (VDD, VDDA, VDD3V3_USBFS) +0.3 V, the internal Pull-up and Pull-Down resistors

must be disabled.

10. Independent from any other supply.

11. Min(VDD, VDDA, VDD3V3_USBFS) +3.6 V < 5.5 V. This formula has to be applied on power supplies related to the IO structure

described by the pin definition table.
