Hi.

We would like to store some data in a backup registers using supercap as an additional power supply.

Do you have maybe any recommendation for the circuitry around the supercap? Or maybe an example of it? It should be quite robust.

Thanks a lot

hi odib.matic,

Depending on used device, you should find an application note (

Getting started with xxxxxxxxxxx MCU hardware development)

providing recommendations on how to design your PCB.

In the case of STM32F407 for example, it is the
