GENERAL DESCRIPTION

Zilog's Z86L04/L08 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
three ports, and are configurable under software control to
provide timing, status signals, or parallel I/O.

P R E L I M I N A R Y

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 communi­cations. Additionally, two on-board comparators process
analog signals with a common reference voltage (Figure

1).

Notes:

Stresses greater than those listed under Absolute
Maximum Ratings may cause permanent damage to the
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.

Total power dissipation should not exceed 462 mW for the
package. Power dissipation is calculated as follows:

Total Power dissipation = V

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 5).

1. This applies to all pins except where otherwise noted.

2. Maximum current into pin must be ± 600 µ A.
There is no input protection diode from pin to V
