Another advantage of AVRs is better noise immunity
than some other processors. I had a Motorola 68HC908GP32 in a dip package
on a board that would reset with a single 4kV near field discharge. I
put an ATMega128 on a dip adapter board and pinned it out to work on the same
board - handled a 10kV near field discharge just fine even when being hit
repeatedly at 20Hz. Everyone says they've designed for noise immunity, but
for me, this experiment proved that the AVR was better than a Mot GP32 so 2yrs
ago I became a convert and haven't looked back.
If you need more reasons, how about simple
in-circuit programming with an AVRISP that you can get for 30 bucks (compare
that to no in-circuit programming or expensive programmers for others), and a
wide selection of inexpensive or even free compilers (winavr &
codevisionavr) compared to the $3500 I spent for the compiler for my Mot GP32
that's gathering dust as we speak.
