Howdy,

		[please note: this message is cross-posted]

I'm in need of a processor to act as the controller for an embedded
system.  It will need to be able to deal with 8 or so inputs (analog
to digital stuff would be cool but not necessary, and if needed I
could do up some kinda multiplexing to deal with extra inputs), be
cheap, be non-power consuming, and hopefully be able to talk easily to
a TI THCT4502BN memory controller that's running 256k simms.
Additionally, it should be fairly robust, as it will need to deal with
a pretty harsh environment.

So that you have more of an idea what I'm doing, I'm designing a
second generation data acquisition system that records relevant data
from a racing motorcycle (things like suspension movement, rpm,
throttle position, exhast gas temp, etc); keeps it around until the
bike gets back into the pits; then uploads its data to a trackside pc.

The first generation system was built as far as it needed to be about
two months ago.  In that system we used custom logic implimented on
PAL's to control the writing of sensor data to memory, through the
TI memory controller above.  We found some problems with PALs, the
major ones being: power consumption, relative lack of adapability, and
us needing to design the logic.  I'd like to go to a processor
(simple one probably) to allow for a more adapable system as well as
(hopefully) easier implimentation.

Also, pointers toward the proper places to contact for
hardware/software docs for various processors would be handy.

Thanks for any help,

Mark
