GENERAL DESCRIPTION
The Z8PE001 is the newest addition to the Z8Plus Micro-
processor (MPU) family. Similar to the Z8E000 and
Z8E001, the Z8PE001 offers easy software development,
debug, prototyping, and an attractive One-Time Program-
mable (OTP) solution.
DS009200-Z8X0799
For applications demanding powerful I/O capabilities, the
Z8PE001’s dedicated input and output lines are grouped
into two ports, and are configurable under software control.
*This document is considered preliminary until the completion of full characterization.

GENERAL DESCRIPTION
(Continued)
Both the 8-bit and 16-bit on-chip timers, with several user-
selectable modes, administer real-time tasks such as count-
ing/timing and I/O data communications.
Note:
All signals with an overline are active Low. For exam-
ple, B/
