Title: Atmega8 Equivalent
Post by: ksquared on December 21, 2009, 10:13:30 PM
 I Tried to hook up the electronics poriton of the $50 robot tutorial a long time ago, but it did'nt work, and I decommissioned the project to reuse the board.  (Surprisingly, it worked) and I'm gonna try that tutorial again.

I went over that circuit so many times that I'm begining to think my chip is bad.  What other chips are interchangeable with the Atmega8?  Digikey is out of stock on the Atmega8. Would the ATMEGA168-20PU-ND (that being a digikey identifier?) do it?

Oh, and thanks for any help!

Any atmega168's or atmega328's in dip form will work.

The 168s are going to be phased out, use the 328.

Why is the 168 being phased out, old technology, obselete, replaced by another mcu?

the 328 is the exact same thing but with more memory, so why keep making 168's?

Oops, well actually the "normal" 168s are being replaced by the 168PA (same picoPower class as the 328P)

thats understandable then.

The reason i was supriesed to here it as Futurlec Australia don't even stock the 328's in any form.(they are slowly catching up)
