I have 100 units with uPSD3334DV
From some reason during the operation in 10 units the CPU stoped function
and change the out-port data - after power cycle the system return to work properly
I checked Volatges, Crystals and it was fine
I know it too general - but do somebody have any idea what can cause this
problem

Hello,
I had the same problem. The reason was that the I used the battery backup function for the SRAM. The battery voltage was rising above Vdd and the SRAM goes to protected mode.
Best Regards,
