TMS320F28335-Q1: TMS320F28335PTPQ vs SM320F28335PTPS

Part Number: TMS320F28335-Q1

Hi there, looks like the SM320 version here SM320F28335PTPS, is the extended temp version (-55C to 150C). I skimmed the datasheets, and the core F28335 seems the same. 

Any distinct electrical differences?

Any software codes/library… impacts if changing SM320F28335PTPS from TMS320F28335PTPQ? Please advise.

Also, I do notice a -EP version as well, how does that compare to the TMS320F28335PTPQ OR SM320F28335PTPS. Similar questions on differences.
