LPC4333 Internal EEPROM Endurance and Wear Levelling.

Hi,

I am trying to understand the the datasheet for the EEPROM Endurance.

I can see that the EEPROM has a minimum of 100K erase/write cycles.

Is this per word, per page or just in total?

The EEPROM has 128 pages x 128 bytes.

I need to write a wear levelling algorithm to give me the maximum endurance. I only need to write 1 word at a time.

So, for example, if I write my word at consecutive locations within a page would this give me 128 * 100K cycles?

Or if I write my word on consecutive pages would this give me 128 * 100K cycles?

Or further If I was to write my word at consecutive locations within a page in consecutive pages would I get 128 * 128 * 100K cycles?

Please can someone advise what would give me the best endurance for a single word that needs to be stored repetitively?

Thanks.

Hello @RikkiB

I think it is a total of 100k. I see you created a ticket on the private service. My colleague has escalated it. He will reply to you on that case. Thanks.
