Like I said...

Atmel, the micro Arduino is using, manufactures a large range of chips form 8
pin up to over 100 pin. Somewhere in there their is most likely a micro that
will do the job for me. The problem is Arduino limits themselves to less than a
handfull.

Say for a project you want to use one 8-pin port to read a keypad, one 8-pin
port to control an LCD character display and two pins on a third port to control
a remote device via the RS-232 pins. I have used an 8515 to do just that. That
was about 7 years ago. It has never failed and is still working today. As far as
I know Arduino has nothing that has 3 8-pin ports on it.

Sure, I could have done that multiplexing the use of the ports but having
specific ports to do specific things, no timesharing, made life easier for my
first commercial project.

I think SparkFun and others have it.

The last article went over using WinAVR to program it.

about a month or two ago I purchased the Arduino Duemilanove. It has the
ATmega328. Started looking around, found out that is about all they support. If
I needed a smaller, more cost effective, or bigger, because I needed more
computing power, I'm out of luck. I didn't want to get tied down to such a
limited setup.
