I am working on hardware design with TMS320F28379DPTPS, I dont have a actual part on hand, I would like to know the actual size of the exposed pad. The drawing show the pad size is about 8 mm by 8 mm, and the recommended pcb pad size on top layer is about 22mm X 22 mm, do I have to use this big pad for this micro controller? Anyone has an actual picture of this part? Thanks.
