Title: ATMEGA8 Crystal question
Post by: Conscripted on August 09, 2009, 07:11:29 PM

Hello all
I want to add a crystal clock to my atmega8 for my next project. I read the crystal tutorial here on SOR. After searching digikey a while and reading the datasheet for the MCU I think i have picked my parts. Will these work? Capacitors (http://search.digikey.com/scripts/DkSearch/dksus.dll?lang=en&site=US&KeyWords=490-4173-ND) <a href="http://search.digikey.com/scripts/DkSearch/dksus.dll?lang=en&site=US&KeyWords=CTX056-ND&x=18&y=5>Crystal[/url]
Thanks

well, it'll work if you want 8mhz speed ;D
i always thought the caps were 22pf each?
but i have heard something about 18pf, ill look around...

It doesn't really matter too much, just anything around 20pF will work.
