user64047: It's possible use external interrupts/attachInterrupt() with the ATtiny85 when I program with Arduino IDE?
If is possible, how many inputs (for external interrupts) the ATtiny85 have and which are they?
Someone have an example code?

user4143: Pin PB2 is the only pin that has a real external interrupt.  This is INT0.
Whether you can use attachInterrupt(0, ...) or not is entirely down to whether it is implemented in the core that you are using.
