Conclusion

The STM8S003F3P6TR is recognized for its ability to safeguard the Flash program memory and data EEPROM against accidental memory overwrites caused by software malfunctions. And there are two levels of write protection.

In addition, this write protection can be removed by writing a large number of key sequences in the control registers in order to perform in-application programming (IAP), which allows the application to modify the contents of the main program memory and data EEPROM, or to reprogram the device option bytes. Its security and reliability is very high.
