STM32F373VCT6 controller damage or 3.3V to GND short

Hi team.

We have been using the STM32F373VCT6 microcontroller across three different projects for the past three years. However, during testing and debugging time we’ve encountered a recurring issue where the controller is getting short between the 3.3V supply and ground suddenly. This problem has occurred multiple times and is affecting our development process. We kindly request your support in identifying the root cause of this problem.

You're going to need to give a lot more detail for people to be able to help you with that!

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

And tell us what you had connected to those boards, especially peripherals with supply voltages of 5V and higher, and those related to inductive loads (like motors or voltage converters).

I have STM32 boards that or more than 10 years old, used frequently, and which still work fine.
