The XC223[04]L is delivered with all Flash sectors erased and with no protection
installed.
The data retention time of the XC223[04]L’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
Note: Operating Conditions apply.
