Motorola has EVBs for the 68332. You can also find data about the chip at bode.ee.alberta.ca ( i hope that is correct ). There is a port for a C compiler available along with freeware assemblers. The Motorola databook for this chip gives a sample of an engine management system, fuel injection, crank trigger, and ignition. They don't give you any circuits but hint that it shoud be pretty simple.

How about | an evaluation or prototype system, which has the RAM, EEPROM (flash would | be nice), A/D's, serial port, etc? The last I heard, the evaluation boards where in the $700 range for the cheapest of the series. I can build (and have started) a 16MHz 68HC000 with 512k EPROM, 16k battery backed-up SRAM, 512k DRAM, timer(s), UART, status LED's, and wacthdog timer for about $375. Sound like a lot of EPROM/DRAM? I envision a system that can store everything for, say, the past 20 seconds and recall it latter for diagnostic purposes. I would also like to play with predictive filters on the MAP and TPS inputs to improve throttle response (ie., no explicit acceleration enrichment term in the injector duration equation). Maybe even a little fuzzy logic? I figured that I would start with this CPU and then switch to one of the CPU32's when the prices drop. They are software compatible (for the most part). GNU's GCC and GAS seem like the best choice for a compiler and cross-assembler. I have both running now and am in the process of wire-wrapping the 68HC000 board(s).
