Z8E001
CMOS OTP Microcontroller
GENERAL DESCRIPTION
Zilog's Z8E001 Microcontroller (MCU) is a One-Time Pro-
grammable (OTP) member of Zilog’s single-chip Z8^Plus
MCU family that allows easy software development, de-
bug, prototyping, and small production runs not economi-
cally desirable with masked ROM versions.
For applications demanding powerful I/O capabilities, the
Z8E001's dedicated input and output lines are grouped
into two ports, and are configurable under software con-
trol.
Both 8-bit and 16-bit on-chip timers, with a large number of
user selectable modes, offload the system of administer-
ing real-time tasks such as counting/timing and I/O data
communications.

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).
