microcontrollers slightly more powerful than a pic?

[Marteney, Steven J.]

Sorry for the last one clicked send like a moron b4 I typed anything.  My
all time favorite uC from Motorola is the 68HC711E9.  From Newark, I think
you can still order the 68HC11E9/EVBU development kit.  I'd recommend not
getting the EVB kit.  It's more expensive than the EVBU and harder to work
with.  The EVBU has a nice "prototyping" area.  Also, Motorola had an add-on
chip, the 68HC24, which allowed the use of an external memory without
sacrificing the GPIO of Ports A and B needed for the E9's on-board memory
controller.

If you want "power" the 50MHz and 100MHz Scenix Semiconductor uC's are PIC
knock-offs but I don't think support a large memory i/f, which I think you
are looking for.

Steve

Well, one microcontroller like "but not PIC" is the Atmel AVR flash
microcontroller series. The MegaAVR has 128k on board flash, 4k RAM, oodles
of I/O, cost of about $20, and the eval board with development kit is $99
for the Mega, and $49 for the standard AVR series (I bought one of each to
play with). I started looking at them after wandering through the PIClist
archives and noticed a lot of them defecting to the Atmel AVR's. There is a
mailing list that is somewhat helpful, but with everyone doing their own
projects, it can be a bit detached...

Not a Motorla chip, but pretty snazzy nonetheless. See http://www.atmel.com

As for Motorla, try http://www.arrow.com http://www.newark.com
http://www.allied.avnet.com (those are some of my favorite places to shop).
Not sure if all of them carry Motorla, but at least a couple of them will.

HTH,

Andrew
