I've been using the MC68VZ328PV in my designs of late. It is a 68k derivative,
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.
