My STM32 device is overheating and has malfunctioned

Wadeva · ‎2024-09-23

Hello,

We’ve designed a device that uses an STM32 microcontroller to manage various features such as I2C, UART, ADC, IWDG, DMA, Flash memory handling etc. After running smoothly for a month, the device began malfunctioning, drawing 220 mA of current and heating up noticeably. I’m trying to determine the root cause of this issue. Could you provide insights into the possible reasons for this behavior?

Thank you.

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.
