Architectural Overview
Zilog’s Z86E33/733/E34, E43/743/E44 8-Bit One-Time Programmable (OTP) Microcontrollers are members of Zilog’s single-chip Z8® MCU family featuring enhanced wake-up
circuitry, programmable Watchdog Timers, Low Noise EMI options, and easy hardware/
software system expansion capability.
Four basic address spaces support a wide range of memory configurations. The designer
has access to three additional control registers that allow easy access to register mapped
peripheral and I/O circuits.
For applications demanding powerful I/O capabilities, the Z86E33/733/E34 have 24 pins,
and the Z86E43/743/E44 have 32 pins of dedicated input and output. These lines are
grouped into four ports, eight lines per port, and are configurable under software control to
provide timing, status signals, and parallel I/O with or without handshake, and address/
data bus for interfacing external memory.
Note: All signals with an overline are active Low. For example, B/W, for
which WORD is active Low, and B/W, for which BYTE is active Low.
Power connections follow these conventional descriptions:

Notes
1. This applies to all pins except XTAL pins and where otherwise noted.
2. There is no input protection diode from pin to VDD.
3. This excludes XTAL pins.
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 extended period may
affect device reliability.

Electrical Characteristics
CMOS Z8® OTP Microcontrollers
Product Specification

Total power dissipation should not exceed 1.21 W 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 (VOL x IOL)
Standard Test Conditions
The characteristics listed below apply for standard test conditions as noted. All voltages
are referenced to GND. Positive current flows into the referenced pin (Test Load).

1. The VCC voltage specification of 5.5 V guarantees 5.0 V ± 0.5 V and the VCC voltage specification of 3.5 V
guarantees only 3.5 V
2. STD Mode (not Low EMI Mode)
3. Z86E43/743/E44 only.
4. For analog comparator inputs when analog comparators are enabled
5. All outputs unloaded, I/O pins floating, inputs at rail.
6. CL1=CL2=22 pF.
7. Same as note 5 except inputs at VCC
8. Clock must be forced Low, when XTAL1 is clock driven and XTAL2
9. WDT running
10. Auto Latch (mask option) selected.
11. Device does function down to the Auto Reset voltage
12. Max. temperature is 70 °C
