Note:
Zilog’s Z86E33/733/E34, E43/743/E44 8-Bit One-Time Programmable (OTP) Microcon-
trollers are members of Zilog’s single-chip Z8
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.
Power connections follow these conventional descriptions:
