STM32笔记——Power Controller(PWR)

The device requires a 1.8 to 3.6 V operating voltage supply (VDD). An embedded linear voltage regulator is used to supply the internal 1.2 V digital power.
The real-time clock (RTC), the RTC backup registers, and the backup SRAM (BKP SRAM) can be powered from the VBAT voltage when the main VDD supply is powered off.
