GENERAL DESCRIPTION

The Z86E33/733/E34/E43/743/E44 8-bit CMOS One-Time

Programmable (OTP) microcontrollers

are members of

hanced wake-up circuitry, programmable Watch-Dog Tim-

ers, Low Noise EMI options, and easy hardware/software

system expansion capability.

Four basic address spaces support a wide range of mem-

ory configurations. The designer has easy access to regis-

ter 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 config-

urable under software control to provide timing, status sig-

nals, and parallel I/O with or without handshake, and ad-

dress/data bus for interfacing external memory.

Notes: 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).
