Provided that your design does not stress the chip beyond the limits specified in the datasheet, it should last indefinitely!
In theory, at least. In practice, there are a few things that do "wear". Flash memory for example has a guaranteed data rentention period (usually a decade or more, but still finite). Then there might be components on the board that have a limited lifetime (certain electrolytic capacitors come to mind). Basically, you need to find the lowest lifetime of the components of your board, and that is the guaranteed time the board should work, provided it was designed correctly and isn't subject to too much abuse. |
