About handling pins named "Unused"

[tatsuya]

Hi team,

I'm developing a our PCB equipped with STM32MP151AAA3.

Are the following pins named "Unused" okay to remain open?

VDD_Unused

VDD1V2_Unused

VDDA1V8_Unused

Best regard,

Hi @tatsuya​ 

I recommend reading AN5031.

If you don't want to provision your board for future IC replacement with new features (e.g. use STM32MP157C with DSI interface), the _Unused pin could be left open.
