I reviewed the part against the official datasheet using the datasheet as the source of truth and checked for exact pin-count alignment, which is the right validation method for a part project .

Only these project properties are currently set:

These are missing/unset:

Result: No obvious footprint/package or pin-count mismatch.

I spot-checked representative terminals and their ball locations against the datasheet:

Result: The sampled symbol pin names and ball assignments are consistent with the official datasheet.

I did not find:

For a complex MCU part, those fields should be populated so the symbol is easier to use and ERC is more meaningful .

So the project looks structurally correct at a basic level:

But it is incomplete as a high-quality reusable part, because the metadata and pin semantics are largely missing.

If you want this part cleaned up, I would set:

And for the symbol:

If you want, I can take the editable clone and do the full metadata + symbol cleanup for you.
