Introduction
The eZ80F92 Development Kit provides a general-purpose platform for
evaluating the capabilities and operation of ZiLOG’s eZ80F92 microcon-
troller. The eZ80F92 is a member of ZiLOG’s eZ80Acclaim! product
line, which offers on-chip Flash capability. The eZ80F92 Development
Kit features two primary boards: the eZ80
®
Development Platform and
the eZ80F92 Flash Module. This arrangement provides a full develop-
ment platform when using both boards. It can also provide a smaller-sized
reference platform with the eZ80F92 Flash Module as a stand-alone
development tool.

Development Platform Overview
The purpose of the eZ80
®
Development Platform is to provide the devel-
oper 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 eZ80F92 Development Kit features two primary boards: the eZ80
®
Development Platform and the eZ80F92 Flash Module. This arrangement
provides a full development platform when using both boards. It can also
provide a smaller-sized reference platform with the eZ80F92 Flash Mod-
ule as a stand-alone development tool.
The eZ80
®
Development Platform is designed to accept a number of
application-specific modules and Z8- and eZ80
®
-based add-on modules,
including the eZ80F92 Flash Module, which features a real-time clock, an
IrDA transceiver, and the eZ80F92 microcontroller.
The eZ80
®
Development Platform, together with its plugged-in eZ80F92
Flash Module, can operate in stand-alone mode with Flash memory, or
interface via the ZPAKII emulator to a host PC running ZiLOG Devel-
oper Studio II Integrated Development Environment (ZDS IDE) software.
The address bus, data bus, and all eZ80F92 Flash Module control signals
are buffered on the eZ80
®
Development Platform to provide sufficient
drive capability.

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 eZ80F92 Flash MCU, and to develop an application without build-
ing additional hardware.
eZ80F92 Flash Module Interface
The eZ80F92 Flash Module interface provides easy connection of the
eZ80F92 Flash 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 eZ80F92 Flash 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.
