Just an detail: the ATmega8 is cheaper nowadays, than the ATtiny2313 and it has four time more flash (ATtiny2313 can be quite limiting). So if You don't need any special feature of ATtiny2313 (20MHz, a whole 8-bit port, etc..) I'd go for ATmega8....

Using a Tiny2313 should be possible. However, keep in mind that there are just a few hundred bytes left for your application,

As always "Powerswitch" is a good staring point.

@guest: how much do you pay for a atmega8, at which quantities?

Slightly above 30 CZK (czech crowns) for < 10 pcs at my local "drug-store". For tiny2313 something more than 40 CZK. (as for today 1USD = 18,324CZK; 1EUR = 26,370CZK). (As a hobbyst I don't need more...)

@guest: good deal. Here, @ 10pcs, the 2313 is €1.30, and the mega8 is €1.80.
