5 Power control (PWR)
Low-density devices are STM32F101xx, STM32F102xx and STM32F103xx
microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes.
Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx
microcontrollers where the Flash memory density ranges between 64 and 128 Kbytes.
High-density devices are STM32F101xx and STM32F103xx microcontrollers where the
Flash memory density ranges between 256 and 512 Kbytes.
XL-density devices are STM32F101xx and STM32F103xx microcontrollers where the
Flash memory density ranges between 768 Kbytes and 1 Mbyte.
Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers.
This section applies to the whole STM32F101xx family, unless otherwise specified.
5.1 Power supplies
The device requires a 2.0-to-3.6 V operating voltage supply (V
DD
). An embedded regulator
is used to supply the internal 1.8 V digital power.
The real-time clock (RTC) and backup registers can be powered from the V
BAT
voltage when
the main V
DD
supply is powered off.
