GENERAL DESCRIPTION
Zilog's Z86C02/E02/L02 microcontrollers (MCUs) are
members of the Z8® single-chip MCU family, which offer
easy software/hardware system expansion.
For applications demanding powerful I/O capabilities, the
MCU's dedicated input and output lines are grouped into
DS96DZ80301
three ports, and are configurable under software control to
provide timing, status signals, or parallel I/O.
One on-chip counter/timer, with a large number of user-selectable modes, off-load the system of administering realtime tasks such as counting/timing and I/O data communi-

cations. Additionally, two on-board comparators process
analog signals with a common reference voltage (Figure
1).
Power connections follow conventional descriptions below:
Note: All Signals with a preceding front slash, "/", are active Low, e.g.: B//W (WORD is active Low); /B/W (BYTE is
active Low, only).

device. This is a stress rating only; functional operation of
the device at any condition above those indicated in the
operational sections of these specifications is not implied.
Exposure to absolute maximum rating conditions for an
extended period may affect device reliability.

1. This applies to all pins except where otherwise noted.
2. Maximum current into pin must be ±600µA.
There is no input protection diode from pin to VDD.
3. This excludes Pin 6 and Pin 7.
4. Device pin is not at an output Low state.
Total power dissipation should not exceed 462 mW for the
package. Power dissipation is calculated as follows:
Total Power dissipation = VDD x [IDD – (sum of IOH)] + sum of [(VDD – VOH) x IOH] + sum of (V0L x I0L)
STANDARD TEST CONDITIONS
The characteristics listed below apply for standard test
conditions as noted. All voltages are referenced to
Ground. Positive current flows into the referenced pin (Figure 6).
