I have STM32G030J6 with 32kB Flash and I need emulate EEPROM. Is it possible?

[Stastny.Petr]

I need permanently save configuration data (several bytes only) in STM32G030J6 in SO8N package. I tried to use EEPROM emulation SW but not working - very robust and complicated. Is there some easy way how to do this? There is no other EEPROM and no possible to connect.

The suggestion of @ne562 is a good idea, but the guaranteed write cycle endurance of the STM32G030 is 1000 cycles - guaranteed over the entire temperature range! Of course higher numbers can be achieved in restricted temperature ranges and especially at lower temperatures, but this is not part of the respective data sheet.

I agree, at extreme temperatures (over 80..100deg.C) number of cycles can be significantly lower (leakage current increases exponentially).

I tested at 22deg and 60deg - no detectable difference, in my applications MCU rarely heats over 40deg...
