The customer shipped 2k, found 4 abnormal, LPC1754FBD80 60-pin TX to ground short circuit; There is a short circuit of Pin 51 RTS1 to the ground in some individual sea. May I ask what is the cause of this problem in mass-produced goods.
Hi @chenhuang
Please submit a case to NXP support team

Maybe failure analysis is needed.
