50-100000, Think it is in the FAQ on the Atmel web page
You also have to take care about the sectors.
You should keep a counter for each sector how many erase cycles in the
sector.
Every page in the sector needs an erase cycle every 10,000 counts of this
counter.

Atmel Data Flash - 15:34 21-02-05

Hello,

Does anybody have info about the average write cycles of Atmel data
flash sectors before wear-out occurs?

Maybe I overlooked it, but I could not find anything in the data
sheets.

A mail to Atmel did not lead to any response.

Thanks for any reply.

Thomas

I believe its 100,000.
I thought it was on the first page of the datasheet.
If not, it would definitely be in the electrical specifications section at 
end of datasheet.

Thanks for the reply,

I meanwhile found a note in AN-9 on Atmel's web site:
"Using the new Data Flash AT45DBxxxC"

100000 cycles are guaranteed, you are right.

Interestingly, there really is no info on that in the data sheets, at
least not in the AT45DB161 one.
