  • Yep! The ATtiny85 ships with a fuse that makes them operate at internal 1MHz. That fuse can be changed to operate at 8MHz internal. If you need to go above that (or need better precision than the internal oscillator) you can set the fuses to operate with an external oscillator. 20MHz is the maximum external oscillator allowed.
