Hello Rob, Sorry for the confusion here. The pin-out on the device/package itself has not changed. Only the ball labels on our datasheet and schematic models have rotated. This was done to bring the FR5739 in line with the conventions of other FRAM products. If you look at the difference between the old datasheet and new, you will see that the absolute potion of the pins have not changed (pin labels [DVCC, PJ.5, etc.]), only the ball designator (E2, D1, etc.). This means if you have a board designed with the old ball labels in pace and order a new part, it will still work in the same orientation. You may have to update your Schematic Model and layout nets for new designs. Regards, JH
