32 bit Microcontrollers

[ernestsnaith]

As part of a universiy project i am desiging a primitive engine managment system. I am currently using a 16 bit demo board, DEMO9S12XDT512. Although it is very much possible to use this i am finding that i am spending a lot of time dealing with 16 bit limit, and the extra code uses more processing time.

I do not have a lot of experience with microcontrollers and am writing in C with CW.

Is there a 32 bit microcontroller that I could use with limited funds? Or a demo board?

Cheers

Hi, Ernestsnaith:

An automotive application? Have you looked at the Freescale automotive processors?

I recently received this evaluation board:
http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MAC7111LCEVB#

It is an ARM7 32-bit processor, with plenty of everything: half meg of flash, 32k Ram, 16 AtoD channels, 16 timer channels, 4 CAN ports, 2 RS232 ports . . .

Since it is an ARM7, there are plenty of good, free GNU tools available.

It might be overkill.
