GENERAL DESCRIPTION

Zilog's Z86E04/E08 Microcontrollers (MCU) are One-Time

Programmable (OTP) members of Zilog’s single-chip Z8

MCU family that allow easy software development, debug,

prototyping, and small production runs not economically

desirable with masked ROM versions.

For applications demanding powerful I/O capabilities, the

Z86E04/E08'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, offload the system of administering

real-time tasks such as counting/timing and I/O data com-

munications.

Note:

All Signals with a preceding front slash, “/”, are

active Low, for example: B//W (WORD is active Low); /B/W

(BYTE is active Low, only).

Power connections follow conventional descriptions be-

low:

ABSOLUTE MAXIMUM RATINGS

Stresses greater than those listed under Absolute Maxi-

mum Ratings may cause permanent damage to the de-

vice. This is a stress rating only; functional operation of the

device at any condition above those indicated in the oper-

ational sections of these specifications is not implied. Ex-

posure to absolute maximum rating conditions for an ex-

tended 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

x [I

- (sum of I

)]

+ sum of [(V

- V

) x I

]

+ sum of (V

x I

)

Notes:

1. This applies to all pins except where otherwise noted. Maximum current into pin must be ± 600 µA.

2. There is no input protection diode from pin to V

(not applicable to EPROM Mode).

3. This excludes Pin 6 and Pin 7.

4. Device pin is not at an output Low state.

The minimum operational V

is determined on the value of

the voltage V

at the ambient temperature. The V

increases as the temperature decreases.

4. The V

voltage specification of 3.0 V guarantees 3.3 V ± 0.3 V with typical values measured at V

= 3.3V.

The V

voltage specification of 5.5 V guarantees 5.0 V ± 0.5 V with typical values measured at V

increases as the temperature decreases.

4. V

= 4.5V to 5.5V, typical values measured at V

= 5.0V

5. Standard Mode (not Low EMI Mode)

6. Z86E08 only

7. All outputs unloaded and all inputs are at V

or V

level.

8. If analog comparator is selected, then the comparator inputs must be at V

level.
