I was about to place an order for some Parts TM4C123GH6PMIR parts since they are cheaper than the TM4C123GH6PMI (no "R" at the end) by a couple of bucks. However, when I went to place the order on the TI site, the checkout cart showed these were "pre-production" parts. I found the same with TM4C1230H6PMIR parts.
The pages for these parts don't mention them as "pre-production", yet when I go to buy them I get a warning. Are all part variants ending in "R" "pre-production"? Why doesn't the page for the parts mention their production status? I'm concerned about designing them into a project and then discover I made a mistake if TI decides to not go into production.
Can anyone shed some light on this?
