Ok, I'm interest to know the maxium word program time.If I have the maxium
program time for one word, after I can calculate my program time multiply
the time for my word number.
Also when I want write, all the memory location are already erased, so
sector erase time is not important for me.
I need to write only in Data Flash.

If I haven't this time I need to use a external serial FRAM memory!!! Regards,

Internal flash memory seem be right for this. The problem is that I not

programming time of internal flash. Does anyone have an idea on this time ?
It seems difficult to obtain!!
Thanks
