STM32G050C8T6 ADC_IN11: inconsistency in the datasheet?

AHame · ‎2024-04-08

Hello,

According to the datasheet PB7 can be used as ADC_IN11.

Is this an error in datasheet? ADC_IN11 is already used by PB10 and cubeMX doesn't seem to allow me to use PB7 or to remap this pin. How can I use ADC_IN11 on pin PB7 as mentioned in datasheet?

Thanks

Hi @AHame,

the DS is unclear as it indicates two possible bondings of the ADC inputs without making the distinction between packages. A decision was made to make the ADC inputs available on smaller packages even if the primary pin dedicated for the function is not available.

So LQFP48 has for example ADC_IN11 bonded to PB10, but as PB10 is not on small packages, the ADC_IN11 is rerouted to PB7 on those. But on LQFP48, ADC_In11 is only on PB10.

I explained the situation to the datasheet responsible and it should be fixed soon.

BR,

I read you message again I understand what you mean now. This datasheet is clearly misleading and should indeed be fixed...
