I
found were some
other 68Ks that were in the $8-$10 range.
I've been using the MC68VZ328PV in my designs of late. It is a 68k has a nice set of I/O, and is cheap. I did have
problems locating a source
for single quantities, so I just bought a tray of 60... They are TQFP 144,
so
they don't have the problems that a BGA package
does for prototype work.
The
MC68EZ328 is another version which is slightly slower
and has less I/O.
The
GCC compiler tools work well with these as they are
68k based.
I found those at $28 each (qty 1), but that seems pretty high for a
microcontroller. That's at least half the parts budget, for most of the
projects I am thinking of. So I still have the "where" question :-).
TQFP-144...I guess I could figure out how to attach that to my homemade
PCB...something tells me you have way nicer tools than I do.
