I asked this question ATMEL support, but I wonder if anybody has stumbeled over the same questions before.

Question: is more information available on the 10year data retention in Flash of the ATMEL Flash Controllers?
How is the probability that also the flash bootloader of a CC01 is lost after 10years? Is there anything that can be done to make this time longer, for example after almost 10years, I reprogram the device, then it will keep its program another 10years, even if the boot loader will be gone.

PS.
-10years seem to be a long time, but I still have working devices of control boards I built about 15years ago.
-Another thing: our assembly partner has parts that are already 3years old.
-10years @ 80°C might give total different results than 10years @ 30°C
