4.5
The XC226x is delivered with all Flash sectors erased and with no protection installed.
The data retention time of the XC226x’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

1) Programming and erase times depend on the internal Flash clock source. The control state machine needs a
2) A maximum of 64 Flash sectors can be cycled 15,000 times. For all other sectors the limit is 1,000 cycles.
3) This parameter limits the number of subsequent programming operations within a physical sector. The drain
Access to the XC226x Flash modules is controlled by the IMB. Built-in prefetch
mechanisms optimize the performance for sequential access.
Flash access waitstates only affect non-sequential access. Due to prefetch
mechanisms, the performance for sequential access (depending on the software
structure) is only partially influenced by waitstates.
Data Sheet
few system clock cycles. This requirement is only relevant for extremely low system frequencies.
In the XC226x erased areas must be programmed completely (with actual code/data or dummy values) before
that area is read.
disturb limit is applicable if wordline erase is used repeatedly. For normal sector erase/program cycles this
limit will not be violated.
