Z86C11 - Zilog

Z86C11 CMOS 4K ROM MCU

The Z86C11 microcomputer (Figures 1 ~nd 2) introduces a new level of sophistication to single-chip architecture. Compared to earlier single-chip microcomputers, the Z86C11 offers faster execution; more efficient use of memory; more sophisticated interrupt, input/output and bit-manipulation capabilities; and easier system expansion.
