GENERAL DESCRIPTION
The Z86E33/733/E34/E43/743/E44 8-bit CMOS One-Time
Programmable (OTP) microcontrollers are members of
Zilog's Z8
®
single-chip microcontroller family featuring en-
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).
