Flash Memory Parameters
The XC2797X is delivered with all Flash sectors erased and with no protection installed.
The data retention time of the XC2797X’s Flash memory (i.e. the time after which stored
data can still be retrieved) depends on the number of times the Flash memory has been
erased and programmed.
Note: These parameters are not subject to production test but verified by design and/or
characterization.
Note: Operating Conditions apply.
