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!!!

Internal flash memory seem be right for this. The problem is that I not know the maximun programming time of internal flash. Does anyone have an idea on this time ? It seems difficult to obtain!!
