UM022403-1008 Introduction

Introduction

Zilog’s Wireless Zdots®Single Board Computer (SBC) Development Kit provides a gen-

eral-purpose platform to evaluate the capabilities and operation of Zilog’s eZ80F91 micro-

controller unit (MCU) and the Realtek 8711 Wireless Transceiver. The eZ80F91 is a

member of eZ80AcclaimPlus!™product family, which offers on-chip Flash capability.

The Wireless Zdots SBC Development Kit features two primary boards— the

eZ80AcclaimPlus! Wireless Zdots SBC and a base board. The Wireless Zdots SBC Devel-

opment Kit provides a full development platform when using both the boards. It can also

provide a smaller-sized reference platform with the Wireless Zdots SBC as a stand-alone

development tool.

Kit Features

The key features of eZ80AcclaimPlus! Wireless Zdots SBC Development Kit include:

•

eZ80AcclaimPlus! Wireless Zdots SBC

Wireless Zdots®SBC Development Kit

Overview

The Wireless Zdots SBC Development Kit provides a set of tools to evaluate the features

of eZ80F91 MCU and the Realtek 8711 Wireless transceiver to develop a new application

before building the application hardware. The eZ80AcclaimPlus!™Wireless Zdots SBC

Development Kit, together with its plugged-in Wireless Zdots SBC, can operate in stand-

alone mode with Flash Memory, or interface via USB Smart Cable (or any Zilog®debug

tool) to a host PC running ZDS II Integrated Development Environment (IDE) software. A

block diagram of the eZ80AcclaimPlus! Wireless Zdots SBC Development Kit and the

Wireless Zdots SBC is displayed in Figure 1.
