GENERAL DESCRIPTION
The Z86E33/733/E34/E43/743/E44 8-Bit One-Time Pro-
grammable (OTP) Microcontrollers are members of Zilog's
single-chip Z8
®
MCU family featuring enhanced wake-up
circuitry, programmable Watch-Dog Timers, Low Noise
EMI options, and easy hardware/software system expan-
sion capability.
Four basic address spaces support a wide range of mem-
ory configurations. The designer has access to three addi-
tional 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 config-
urable under software control to provide timing, status sig-
