I recently have a tested parts that have a slight different Revision on both the label and the die marking, A1 vs A2.
Looking at one of the previous post someone else made on the forum, it seems that the second digit on the revision denotes fab location. (Link to the post below)
From the PCNs that were released for this part, 20170627002 and 20161215002, my understanding is that the RFAB and NFME were added as additional production sites.
Is it normal for TI to have a slight different revision on the label in comparison to the die marking revision?
