The eZ80® Sales Demonstration Platform works with the eZ80L92,
eZ80F91, and eZ80F92 modules. For simplicity, this document refers to
the eZ80L92 module. Instructions apply to all three modules, however.
Introduction
The eZ80® Sales Demonstration Platform provides a flexible, portable platform for
conducting training programs and demonstrations using a number of ZiLOG
microcontroller and microprocessor devices. A ZiLOG eZ80®processor-equipped
module plugs into this platform.
Figure 1 shows the top view of the eZ80® Sales Demonstration Platform.

The eZ80® Sales Demonstration Platform can be powered by the on-board batter-
ies (stand-alone configuration) or by the AC adapter. Both configurations feature:
• Serial communication using eZ80®UART ports and adapter board connectors
• Ethernet communication using the eZ80L92 or eZ80F92 module
• LCD displays relevant demo data
• ZDI operation using external ZPAK
Do not use battery power and AC power at the same time. Doing so will damage
the board.

eZ80® Sales Demonstration Platform Setup
Overview
A single software project called ez80l92_demo_platform.pro is included on the
eZ80® Sales Demonstration Platform CD-ROM. The demo software is preloaded
into eZ80L92 Flash memory. Connect the demonstration platform to a PC as
described below and the demo is ready to run.
Instructions for loading the demo project are also included for code download and
debugging demonstrations.
PCB Notes
• To use batteries in this demonstration, load four 1.5-Volt batteries into the bat-
tery holder and turn on battery switch S1.
• X10 port J10 is not loaded for this release.
• The LCD module is a Matrix Orbital LCD2041. For further information about
the Matrix Orbital LCD2041 20-column by 4-line display, go to www.matrixor-
bital.com. This LCD display is a 5-volt display with an I2C or RS-232 interface.
This kit uses the I2C interface only.
Demonstration Setup Procedure
Ensure that the eZ80® Sales Demonstration Platform is configured and working
properly as described in the eZ80® Sales Demonstration Platform Quick Start
Guide (QS0024). Then disconnect the ZPAKII from the PC and platform and per-
form the following procedures. Use Figure 4 as a reference.
