Flash Memory Parameters
The XC2734X is delivered with all Flash sectors erased and with no protection installed.
The data retention time of the XC2734X’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.

1) The unused Flash module(s) can be erased/programmed while code is executed and/or data is read from only
one Flash module or from PSRAM. The Flash module that delivers code/data can, of course, not be
erased/programmed.
