Hi all, I'm using uPSD3234 to develope an application. I want to know the life time of uPSD3234's Flash Memory. How many times can I write or erase the Flash Memory till it fails to read and write correctly?

Thanks.

Flash memory - 100,000 minimum

PLD - 1,000 minimum

Thanks for your reply.

In my application I want to save a counter in the Flash Memory so that I can retrieve the counter after power-down and on. The counter may be read and write in an fixed address very offen, so I worry about the validity of the counter after a long time running. But I think 100,000, as you said, is enough for me.
