GENERAL DESCRIPTION Z86C10/C20 microcomputer (Figures 1 and 2) introduces a new level of sophistication to single-chip architecture.
Compared to earlier single-chip microcomputers, the Z86C10/C200ffers faster execution; more efficient use of memory; more sophisticated interrupt, input/output and bit-manipulation capabilities; and easier system expansion.
