A.3.2
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 data retention and program/erase cycling failure rates 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.
The standard shipping condition for both the D-Flash and P-Flash memory is erased with security disabled.
However it is recommended that each block or sector is erased before factory programming to ensure that
the full data retention capability is achieved. Data retention time is measured from the last erase operation.
