GENERAL DESCRIPTION
Zilog’s Z86C04/C08 are members of the Z8 ® MCU singlechip microcontroller family which offer easy software/hardware 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 software 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 communications.
Additionally, two on-board comparators process analog signals with a common reference voltage (Figure 1).
