Hello,

These numbers are set very conservative, the flash IP used is actually qualified to 10years @ 85°C, but we do our own qualification, which is tested to 48years @ 40°C. However since the target application is consumer products, we have only specified minimum 10years @ 40°C in the datasheet. In any case you can rely on the flash retention to last for many, many years to come.

Cheers,

Kenneth
