Hi team,

I ask this for my customer.

But I can't find it in datasheet and it shows F15 is VDDIO

    Hi Shuqing,

    You are looking at the schematic? I believe this is an older altium library component where the component was taking from the F28P650 256bga footprint, so it is not the latest device specification for the F29H85. The UltraLibrarian files should have the latest spec and the schematic should be updated on the next revision of the device (I will also file a bug fix to ensure that)

    Regards,

    Peter
