Hello,

I want to connect mention module to MCU but I am not sure what to do with RTC backup supply. In my design it is not important to use this RTC so I want to just to fulfill "minimum requirements" for module to work properly. In datasheet there are 3 options: simple battery, rechargeable battery and super capacitor.
Can I use simple capacitor (for example 100uF), do I have to make charging circuit for this capacitor? Is it possible to left this pin untied?

Thank you.
