How many times can load software on the flash?

I need to know how many times the software can be loaded into the microcontroller arduino mega 2560 r3? thank you very much

The datasheet says 10,000 write/erase cycles for FLASH. (100,000 for EEPROM)

thank you very much

Actually you can write many times more. However once you pass the datasheet numbers there are no guaranteed retention times anymore. The more often you write the leakier the memory will get. Retention times will degrade accordingly.

Are you saying that the rate of write/erase cycles matters? I thought it was just the total count.

Nope. The total count is what counts.

Unless your write at a rate that is sufficient to heat up the memory of course :wink:

Heat may not be a bad thing (though getting it up to 800 degrees might take a fair amount of current!)
