Attiny85 sleep/Power down mode?

Hello i have read some where in that the attiny85 got a Power down sleep mode or some kind. Wondering if this is true and i was wondering if someone can help me out on this?

The second question is once in sleep/Power down mode how long does it take to Wake up and do its function?

See section 7 of the datasheet

Sleep mode is supported.
Takes a few microSeconds (uS) to wake up, dependent on the clock rate.

Thank you CrossRoads. I never seen or heard of someone putting the attiny85 to sleep i have looked at the atmel sheet. I have seen someone putting the Atmel Atmega 328p to sleep i even tried it my self. But never the attiny85.

Really? See this post about my torch locator.

Hello nick thank you i didn't see that one of yours. this was for some wireless sending stuff a while back.
