Possible Cube MX wrong specs & package for STM32C051K8 ?

Hi,

when selecting the STM32C051K8 in Cube MX it seems that CubeMX has wrong configs/specs about it?

As you can see from the screenshot below it shows it is a LQFP package but - unless I missed something - it is supposed to be a UFQFPN32 package.

The main issues are...

1) when searching for micros with that package, that micro does not appear

2) not sure if the entire CubeMX generated code is somehow affected? Firth thought is that it is just a package difference but the pin count is the same so perhaps it is ok, but perhaps not?

 

Point #2 is the most important at the moment. Could someone form ST please guarantee we can use CubeMX to configure the part?

Many thanks

Hello @Ricko 

Based on the  DS14721 Rev : 

STM32C051KxT-->  LQFP32

STM32C051KxU -->UFQFPN32
