GENERAL DESCRIPTION
Zilog’s Z86C04/C08 are members of the Z8® MCU single-
chip microcontroller family which offer easy software/hard-
ware system expansion.
For applications demanding powerful I/O capabilities, the
Z86C04/C08’s dedicated input and output lines are
grouped into three ports, and are configurable under soft-
ware control to provide timing, status signals, or parallel
I/O.
Two on-chip counter/timers, with a large number of user
selectable modes, off-load the system of administering
real-time tasks such as counting/timing and I/O data com-
munications. Additionally, two on-board comparators pro-
cess analog signals with a common reference voltage (Fig-
ure 1).
