We are developing a low power product that uses STM8L151 MCU. The product is in low power run mode when on idle stage and program is executed from RAM. I was wondering that how reliable is this functionality when device is powered on for years. We use IAR compiler that copies RAM function from flash to RAM only at startup. This worries me a bit... how big is the possibility of RAM corruption? We use IWD but Im not sure if that catches some RAM corruptions that does not affect to IWD refreshing.
