Duggle Posted August 27, 2010 Report Share Posted August 27, 2010 I had a work related project on an ATmega target that mysteriously failed some months into the project development. It turned out that I had exceeded the flash re-write lifetime for the device after much hacking and experimentation (lots of flash programming). I ended up utilising an eeprom based counting feature of the flash programmer software AVRDUDE. It is able to report the number of flash programs on each target chip. Anyhow, I was wondering how many re-flashes can our STM32 take before it fails? Quote Link to comment Share on other sites More sharing options...
TK. Posted August 27, 2010 Report Share Posted August 27, 2010 According to the datasheet STM guarantees 10k cycles at typical conditions (55°C) for 20 years Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
Duggle Posted August 27, 2010 Author Report Share Posted August 27, 2010 Thanks, TK. That performance is very good. I imagine it is even better at 25(degC). The AVRs only last for about 1000 rewrites IIRC. Quote Link to comment Share on other sites More sharing options...
