What is the difference between parts “STM32F429ZGT6�? and "STM32F429ZGT6TR"? W found from the datasheets,"*** = programmed parts,TR=tape and reel" .We think,“programmed parts�?should not be the same as "tape and reel".So the “TR�? really means？Can they be replaced each other pin to pin?Is the software compatible?

These are on a tape, parts usually come on trays

I think full reels, 500 parts.
