bit corruption in Atmel AT89C51ED2 internal flash

hi
working with AT89C51ED2 device from Atmel, has anyone encountered a situation in which a single or multiple bit of the internal flash image file get corrupted?
i need a few hints on this phenomena which prevent correct code execution, major suspicion is brown-out scenario?
Best regards

  • The first question to ask is always: Do you have a supervisor for the supply voltage, that makes sure the processor is always in reset state if the voltage isn't stable?

    Next thing is that the chip requires temperature and voltage to be within range - and the voltage stable - to be able to correctly program the flash.
