Notes:
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 Z86E31 8-Bit One-Time Programmable (OTP) Microcontrollers are members of Zilog's single-chipZ8® MCU family featuring enhanced wake-up circuitry, programmable Watch-Dog Timers, Low Noise EMI options, and easy hardware/software system expansion capability.
Z86E31 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 Z86E30/E31 Z86E31 have 24 pins, and the Z86E40 has 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 par-
