Introduction
The eZ80L92 Development Kit provides a general-purpose platform for
evaluating the capabilities and operation of ZiLOG’s eZ80L92 micropro-
cessor. The eZ80L92 Development Kit features two primary boards: the
eZ80
®
Development Platform and the eZ80L92 Module. This arrange-
ment provides a full development platform when using both boards. It can
also provide a smaller-sized reference platform with the eZ80L92 Module
as a stand-alone development tool.

Development Platform Overview
The purpose of the eZ80L92 Development Kit is to provide the developer
with a set of tools for evaluating the features of the eZ80
®
family of
devices, and to be able to develop a new application before building appli-
cation hardware. The eZ80
®
Development Platform is designed to accept
a number of application-specific modules and Z8- and eZ80
®
-based add-
on modules, including the eZ80L92 Module, which features an EMAC,
an IrDA transceiver, and the eZ80L92 microprocessor.
The eZ80L92 Development Kit features two primary boards: the eZ80
®
Development Platform and the eZ80L92 Module. This arrangement pro-

vides a full development platform when using both boards. It can also
provide a smaller-sized reference platform with the eZ80L92 Module as a
stand-alone development tool.
The eZ80
®
Development Platform can operate in stand-alone mode with
Flash memory, or interface via the ZPAKII emulator to a host PC running
ZiLOG Developer Studio II Integrated Development Environment (ZDS
IDE) software. If the user’s eZ80
®
application demands Internet connec-
tivity and/or a network connection, the eZ80
®
can serve web pages over a
TCP/IP network, allowing easy system monitoring and control, and
effortless processor code updates.
The address bus, data bus, and all eZ80L92 Module control signals are
buffered on the eZ80
®
Development Platform to provide sufficient drive
capability.
A block diagram of the eZ80
®
Development Platform and the eZ80L92
Module is shown in Figure 1.

Operational Description
The eZ80®Development Platform can accept any eZ80®-core-based
modules, provided that the module interfaces correctly to the eZ80®
Development Platform. The purpose of the eZ80®Development Platform
is to provide the application developer with a tool to evaluate the features
of the eZ80L92 device and to develop an application without building
additional hardware.
eZ80L92 Module Interface
The eZ80L92 Module interface provides easy connection of the eZ80L92
Module. It also provides easy connection for any eZ80®-based module
designed to this interface. This includes modules using future eZ80®
devices, and user-developed modules using current eZ80®devices.
The eZ80L92 Module interface consists of two 50-pin receptacles, JP1
and JP2.
Peripheral Bus Connector
Figure 6 illustrates the pin layout of the Peripheral Bus Connector in the
50-pin header, located at position JP1 on the eZ80®Development Plat-
form. Table 2 describes the pins and their functions.
