I wonder how often I can flash an ATtiny85 before the EEPROM will give up.
Solved
Sometimes it is just on the first page of the datasheet:

It reads on the first page of the data sheet.
EEPROM is specified for 100000 write/erase cycles.
It does not depend on how often you do it, no matter how fast or slow it still is 100000 write/erase cycles.

1\$\begingroup\$ Some caveats apply. The EEPROM page size is 4 bytes so if you write four bytes all four memory locations are erased and written four times. Unless you mean the program flash. That's only 10000. \$\endgroup\$– JustmeMar 18 at 16:58

\$\begingroup\$ It seems that I might have meant the flash memory instead of the EEPROM. I use Arduino IDE to upload a simple sketch. To my shame, I don't know what the difference is yet. \$\endgroup\$ Mar 18 at 17:06

\$\begingroup\$ Then even 10,000 cycles should be reasonable. I have mistakenly assumed the limit would be way more less (about 50-100 cycles) and so thought it would be risky to flash it too often during development before I finish my project. \$\endgroup\$ Mar 18 at 17:11
