The eZ80190 Development Kit provides a general-purpose platform for
evaluating the capabilities and operation of ZiLOG’s eZ80190 microprocessor. The eZ8 0F9 1 Develo pmen t Kit features two primary boards: the
eZ80Acclaim!
arrangement provides a full development platform when using both
boards. It can also provide a smaller-sized reference platform with the
eZ80190 Module as a stand-alone development tool.

The purpose of the eZ80190 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
®
application hardware. The eZ80Acclaim!
designed to accept a number of application-specific modules and eZ80
Development Platform is
®
based add-on modules, including the eZ80190 Module, which features an
Ethernet MAC, a Real-Time Clock, and the eZ80190 microprocessor with
a fast Multiply-Accumulate unit.
When attached to the eZ80
®
Development Platform, the eZ80190 Module
can operate in stand-alone mode with Flash memory, or interface via the
ZPAK II debug interface tool to a host PC running ZiLOG Developer Studio II Integrated Development Environment (ZDS IDE) software. If the
user’s eZ80
®
application demands Internet connectivity and/or a network
connection, the eZ80190 microprocessor 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 eZ80190 Module control signals are
®
buffered on the eZ80Acclaim!
Development Platform to provide suffi-
cient drive capability.

To design an application module, the user should be familiar with the
architecture and features of the eZ80190 Module currently installed.
Implementing an application module via the Application Module Interface
requires that the eZ80190 Module also be mounted on the
Development Platform, because it (the eZ80190 Module) contains the
eZ80190 microprocessor. To mount an application module, use the two
male connectors J6 and J8.
Connector J6 carries the GPIO signals, and connector J8 carries memory
and control signals. T ables 4 and 5 list the signals and functions related to
each of these jumpers by pin. Power and ground signals are omitted for
the sake of simplicity.
