I have two questions related to STM32L443CCY6TR microcontroller which I do not understand clearly.
Powering the microcontroller from a battery
The STM32L443CCY6TR microcontroller can be powered from a battery as it has a wide operating voltage range from 1.8V to 3.6V.
Suppose battery is a single-cell lithium-ion battery, which typically provides a voltage range of 3.0V to 4.2V.
Can we connect the battery to the VDD pin of the STM32L443CCY6TR directly or need to use regulator?
