4.1 Power supplies
There are two main power supply schemes:
• V
DD
= 1.7 to 3.6 V: external power supply for I/Os with the internal regulator disabled,
provided externally through V
DD
pins. Requires the use of an external power supply
supervisor connected to the V
DD
and PDR_ON pins.
• V
DD
= 1.8 to 3.6 V: external power supply for I/Os and the internal regulator (when
enabled), provided externally through V
DD
pins.
The real-time clock (RTC), and the RTC backup registers can be powered from the V
BAT
voltage when the main V
DD
supply is powered off.
Note: Depending on the operating power supply range, some peripheral may be used with limited
functionality and performance. For more details refer to section "General operating
conditions" in the datasheet.

1. V
DDA
and V
SSA
must be connected to V
DD
and V
SS
, respectively.
