The failure rates for data retention and program/erase cycling are specified at the operating conditions
noted.
The program/erase cycle count on the sector is incremented every time a sector or mass erase event is
executed.

NOTE: Flash cycling performance is 10 cycles at -40˚C to +125˚C. Data retention is
specified for 15 years.
NOTE: EEPROM cycling performance is 10K cycles at -40˚C to 125˚C. Data retention is
specified for 5 years on words after cycling 10K times. However if only 10 cycles
are executed on a word the data retention is specified for 15 years.
