STM32G431KBT6 SHort-Circuit on VDDA

[elb-lab]

I made two projects using the new 36-pin STM32G431KBT. In both projects, after a few seconds of 3.2 Volt power supply, the VDDA pin is short-circuited with the VSS / VSSA pin definitively. As many as 5 chips broke this way. Is it a manufacturing defect?

Thank you

On the balance of probabilities, likely some current paths or voltage differential on your design.
