STM32G030F6P ADC Frequency in STM32CubeMX

[MKanc.1]

I was checking maximum frequencies of some MCUs and noticed i can pick ADC frequency in CubeMX clock configuration up to 80MHz for TSSOP-20 STM32G030. Its maximum frequency is 64MHz.

Datasheet states it can deliver maximum 2Msps on 12 bit but with its 1.5 Sampling and 12.5 conversion cycles it reaches way higher sample rates.

I checked some of the reference manual chapters and did not noticed anything unusual, prescalers seems to accept /1 divisions as well.

I am not familiar with reference manuals. Datasheet 5.3.17 also shows 35MHz maximum frequency. What's the thing i am missing? Is it a bug on interface?

Hello @MKanc.1 ,

The maximum frequency of STM32G030 is 64MHz as mentioned in the Datasheet.

Which CubeMX version used?

I had 6.12.x something before, updated to 6.13.0 and it is still same.

Stm32CubeIDE 1.16.1 have same issue, accepting ADC frequency up to 80 MHz.
