It looks like this device has 2 versions: F723 and F733. The F723 has rev9 datasheet and does list LQFP-100 as an option for its F723 variant. However, the F733 datasheet is only at rev7 and says only F732 is available.
The F723 does have a pinout available. Afaik both feature the USB-HS peripheral, but the F73x have crypto features. Why these parts have dedicated datasheets: I don't know, maybe because of some export restriction.
Confusing at the very least, moreover suggesting some mistakes on ST's documentation part.
