read operations after reprogramming before the contents could potentially be altered. For example, if the Serial
Flash is being used for boot code storage, then it would take 800,000,000 boot operations before that boot code
may become altered, provided that the boot code was not updated or reprogrammed. If an application was to read
the entire memory array non-stop at a clock frequency of 10MHz, it would take over five years to reach
800,000,000 read operations. Adesto firmly believes that this extended testing result should not be a cause for
concern. We also believe that most, if not all, applications will never read the same portion of memory 800,000,000
times throughout the life of the application without ever updating that portion of memory.

*NOTICE:
Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age to the device. The "Absolute Maximum Rat-
ings" are stress ratings only and functional
operation of the device at these or any other con-
ditions beyond those indicated in the operational
sections of this specification is not implied. Expo-
sure to absolute maximum rating conditions for
extended periods may affect device reliability.
Voltage Extremes referenced in the "Absolute
