Hi,

I was going through table 14 of STM32F050xx datasheet. This table shows IDD-VBAT at various voltages. Just want to check when this measurement is taken whether VDD was pin was floating or grounded?

Hi MCEmbedded,

The VDD pin will be connected to an external circuitry to turn ON/OFF the VDD as the VBat will power only the backup domain and RTC.
