Hi VIGNE SH BALAJI,

From the KEA128 datasheet, you can get that the Flash Program/erase endurance is typically 100K Cycles, the max data is not gave out, we also don't have it.
Flash have the lifetime, it is the character of the flash.
So, when you evaluate this chip's flash cycle, please use the typical data, this data is guaranteed.
About the document, please refer to this link:

Page 22.

Wish it helps you!
If you still have question, please let me know!

Have a great day,
Kerry
