eZ80F91 Development Kit Overview
The purpose of the eZ80F91 Development Kit is to provide a set of tools
for evaluating the features of the eZ80F91 microcontroller and to be able
to develop a new application before building application hardware.
The eZ80Acclaim!
®
Development Kit is designed to accept a number of
application-specific modules and eZ80Acclaim!-based add-on modules,
including the eZ80F91 Module featured in this kit.
The eZ80Acclaim! Development Kit, together with its plugged-in
eZ80F91 Module, can operate in stand-alone mode with Flash memory, or
interface via the ZPAK II Debug Tool or USB Smart Cable
(ZUSBSC0100ZACG) to a host PC running Zilog Developer Studio II
Integrated Development Environment (ZDS II IDE) software.
The address bus, data bus, and all eZ80F91 Module control signals are
buffered on the eZ80Acclaim! Development Kit to provide sufficient
drive capability.

Module is shown in
