DS10183 Rev 11

1. It is recommended to power VDD and VDDA from the same source. A maximum difference of 300 mV between VDD and VDDA

can be tolerated during power-up and normal operation.

2. VDD_USB must respect the following conditions:

- When VDD is powered-on (VDD < VDD_min), VDD_USB should be always lower than VDD.

- When VDD is powered-down (VDD < VDD_min), VDD_USB should be always lower than VDD.

- In operating mode, VDD_USB could be lower or higher VDD.

- If the USB is not used, VDD_USB must range from VDD_min to VDD_max to be able to use PA11 and PA12 as standard I/Os.

- If the USB is not used and PA11/PA12 are not used as standard I/Os, VDD_USB must be connected to a VSS or VDD power

supply voltage (VDD_USB must not be left floating).

3. To sustain a voltage higher than VDD+0.3V, the internal pull-up/pull-down resistors must be disabled.

4. If TA is lower, higher PD values are allowed as long as TJ does not exceed TJ max (see Table 78: Thermal characteristics on

page 115).
