Flash Specifications
This section provides details about program/erase times and program-erase endurance for the flash
memory.
Program and erase operations do not require any special power sources other than the normal VDD supply.
For more detailed information about program/erase operations, see the Memory section.

Data retention4
4 Typical data retention values are based on intrinsic capability of the technology measured at a high temperature and de-rated
to 25
C using the Arrhenius equation. For additional information on how Delta defines typical data retention, please refer to
engineering bulletin Typical Data Retention for Nonvolatile Memory (document EB618/D).
