LPC55 flash wear characteristics

Fastfox — Tue, 07 Mar 2023 13:52:14 GMT

I must be blind, but I cannot find any hints about flash wear/erase cycles for LPC55S69. I would like to store something to flash while operational and I would like to know how many times I can write to one address without problems.

Hi Fastfox

I recommend you check this information in DS

For example, erase time for one page is 2ms typically.

minimal page erase/program cycle is 10000 times.

Best Regards

Hi Jun Zhang,

for the ambient condition T = -40°C - +85°C, I read 100000 number of erase/program cycles. Seems a single "0" has wrapped to a new line in the table.

What do you make of that entry?

Cheers

Daniel

Sorry for the mistakes.

yes, minimal page erase/program cycle is 100000 times.
