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.DescriptionThe Z86E34 8-bit CMOS One-Time Programmable (OTP) microcontrollers are members of Zilog's Z8® single-chip microcontroller family featuring enhanced wake-up circuitry, programmable Watch-Dog Timers,
Low Noise EMI options, and easy hardware/software system expansion capability.
Z86E34 Four basic address spaces support a wide range of memory configurations. The designer has 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.
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).
