I'm curious what everyone thinks of this
issue, and what *are* the
better choices?
The Motorola 68EC000 makes a reasonable microcontroller. 16 MB addressing
range, configurable 8- or 16-bit data bus, a range of operating speeds (far
faster than a 6809), freely available tools, still in full production, and
about $4.00 in single lots. from my days with Software Results (Northwest
Instruments bus analyzer,
Fluke 9000A w/68K pod...)
I realize that these days the 64-pin DIP package is not in favor, but I
do happen to have several hundred if not a small number of thousand CPUs
in that format. In any case, the instruction set is the real win here,
more than the package.
