Hi.

   

I would like to implement a RTC that doesn`t lose the time data after a power failure. I am thinking to use a 5V battery. How do I have to do the connections? Do I have to use de Boost? Which elements do I need?

   

Thanks

The battery vs SuperCap approach dependent on your design criteria for power loss.
