Hello,
The temperature increase is happening before configuration.
This is abnormal elevated leakage in part of the die. Definitely not dynamic switching power.
Are you seeing this behavior at only 1 unit?
Next step:
1-can you try power up with slower ramp time? (within timing spec)
2- how many boards manufactured? All showing same behavior?
3- Is it possible to swap unit on the board with another one? - to see if the issue follows unit or follows board
4- Please send snap shot of the device top marking so I can analysia the production test history.
regards,
Farabi
