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).

Notes:

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

2.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.

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 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 = VDD x [I				– (sum of I )] + sum of
[(V	– V ) x I	] + sum of (V		DD	OH
			x I ).
DD	OH	OH	0L	0L

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 4).

Notes:

1.Port 0, 2, and 3 only.

2.VSS = 0V = GND.

3.The device operates down to VLV. The minimum operational VCC is determined on the value of the voltage VLV at the ambient temperature. The VLV increases as the temperature decreases.

4.VCC = 3.0V to 5.5V, typical values measured at VCC = 3.3V and VCC = 5.0V.

5.Standard Mode (not Low EMI mode).

6.Z86C08 only.

7.Inputs at power rail and outputs are unloaded.

3.The device operates down to VLV. The minimum operational VCC is determined on the value of the voltage VLV at the ambient temperature. The VLV increases as the temperature decreases.

4.VCC = 3.0V to 5.5V, typical values measured at VCC = 3.3V and VCC = 5.0V.

5.Standard Mode (not Low EMI mode).

6.Z86C08 only.

7.Inputs at power rail and outputs are unloaded.
