Hi - I was just wondering - is there a limited number of times that you can write to an AVR? Thanks,
Michael

Hi,
The ATmega8 datasheet says on the first page...
8K Bytes of In-System Self-Programmable FlashEndurance: 10,000 Write/Erase Cycles
512 Bytes EEPROMEndurance: 100,000 Write/Erase Cycles
Most of the devices are similar. You would have to check each datasheet to be sure.

Ever heard of datasheets?

Those are guaranteed limits, but in practise it can be much higher. Have to accept the odd fallout though In a test, parts would reprogram themselves millions of times.

Nope. What are those?

I think it might be misleading to say "most" here. The previous generation (atmega163, etc.) guaranteed only 1,000 cycles for flash, and many of these are still in production with their original process and specification. The 100,000 for the EEPROM has been the case for as long as I can remember.
