Missing VBAT pin in STM32G030F6

I am willing to use STM32G030F6 but VBAT pin is missing as before i was using 32f103 and this got VBAT pin. So my question is for backup register of RTC is there is any dedicated pin in STM32G030F6?

You still can use backup registers and RTC, but they will stop working as soon as you remove VDD.0693W00000HprAnQAJ.pngIf you want a backup battery operation, you have to choose a bigger package, where VBAT is brought out to a dedicated pin.
