Running an 8Mhz at 4Mhz - snaresystems - Jun 27 1:26:00 2000
Hey everyone,<br><br>I'm about to put in a
purchase for a few AVR's and I was looking at some of the
specs of these things. On the SK200 board it comes with
AT90S8515-8PC (8Mhz) and yet has an on board crystal of 4Mhz.
Is it safe to say then if I purchase another 8Mhz
chip I can safely use a 4mhz Crystal for it, if I
decide to goto the lower speed for power
saving?<br><br>Thanks for any help!<br>Nathan

You CAN safely use a 4mhz Crystal for power saving? You can use any frequency down to
0Hz (DC).
