GENERAL DESCRIPTION
Zilog's Z86E04/E08 Microcontrollers (MCU) are One-Time
Programmable (OTP) members of Zilog’s single-chip Z8®
MCU family that allow easy software development, debug,
prototyping, and small production runs not economically
desirable with masked ROM versions.
For applications demanding powerful I/O capabilities, the
Z86E04/E08's dedicated input and output lines are
grouped into three ports, and are configurable under soft-
ware control to provide timing, status signals, or parallel
I/O.
Two on-chip counter/timers, with a large number of user
selectable modes, offload the system of administering
real-time tasks such as counting/timing and I/O data com-
munications.
Note: 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).
Power connections follow conventional descriptions be-
