A.3.2 NVM Reliability
The reliability of the NVM blocks is guaranteed by stress test during qualification, constant process
monitors and burn-in to screen early life failures.
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.
3. Maximum Erase and Programming times are achieved under particular combinations of f
4. urst Programming operations are not applicable to EEPROM
5. Minimum Erase times are achieved under maximum NVM operating frequency f
6. Minimum time, if first word in the array is not blank
7. Maximum time to complete check on an erased block
Refer to formulae in Sections A.3.1.1 - A.3.1.4 for guidance.

All values shown in Table A-12 are target values and subject to further extensive
characterization.
Flash cycling performance is 10 cycles at -40C to + 125C. Data retention is
specified for 15 years.
EEPROM cycling performance is 10K cycles at -40C to +125C. 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.
