esp-wroom-32 SRAM/flash write count

Postby skibbidy » Sun Jun 28, 2020 11:31 pm

I'm trying to find information regarding the number of write cycles I can do on the different memories, primarily the SRAM on the esp-wroom-32 (and flash if available).

We are trying to store small event logs somewhere and would like to know what our life expectancy of the device will be.

Any information or documentation (with page #s) is greatly appreciated.

thanks

SRAM (or do you mean PSRAM? Same goes for that) is RAM and as such has infinite write cycles.
Flash depends on what flash is in the module, but generally you can count on something like 100,000 cycles. If you find what flash is in the module, you can look up the datasheet for it, but most flashes will be somewhere around that number.
