Single-chipper is the key term, though. The Z80
isn't a single-chipper,
nor
is the 64180 or the Z380, or the 6502. The fact that
the parts count is
greater than it would be with a comparably capable MCU is what's made
this
Z80 is available as a library core for fully embedded systems. In that
case
it's very true to the single chip idea. Not unlike some of the 6800,
6502
designs.
