GENERAL DESCRIPTION
The Z86E30/E31/E40 8-Bit One-Time Programmable
(OTP) Microcontrollers are members of Zilog's single-chip
Z8
®
MCU family featuring enhanced wake-up circuitry,
programmable Watch-Dog Timers, Low Noise EMI op-
tions, and easy hardware/software system expansion ca-
pability.
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.
DS97Z8X0502
For applications demanding powerful I/O capabilities, the
Z86E30/E31 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-
allel 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. For example, B/W (WORD is active Low); B/W
(BYTE is active Low, only).
