The EZ-KIT Lite evaluation system contains ESD (electrostatic discharge) sensitive devices. Electrostatic charges readily accumulate on the human body and equipment and can discharge without detection. Permanent damage may occur on devices subjected to high-energy discharges. Proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Store unused EZ-KIT Lite boards in the protective shipping package.

PREFACE

Thank you for purchasing the Blackfin® USB-LAN EZ-Extender®, Ana­log Devices, Inc. extension board to the EZ-KIT Lite® evaluation system for ADSP-BF533, ADSP-BF537, and ADSP-BF561 Blackfin processors.
The Blackfin processors are embedded processors that support a Media Instruction Set Computing (MISC) architecture. This architecture is the natural merging of RISC, media functions, and digital signal processing characteristics towards delivering signal processing performance in a microprocessor-like environment.
The EZ-KIT Lite and USB-LAN EZ-Extender are designed to be used in conjunction with the VisualDSP++® development environment. Visu­alDSP++ offers a powerful programming tool with new flexibility that significantly decreases the time required to port software code to a proces­sor, reducing time-to-market.

Product Overview

Product Overview
The Blackfin USB-LAN EZ-Extender is a separately sold extension board that plugs onto the expansion interface of the ADSP-BF533, ADSP-BF537, or ADSP-BF561 EZ-KIT Lite evaluation system. The extension board aids the design and prototyping phases of the ADSP-BF533, ADSP-BF537, or ADSP-BF561 processor targeted applications.
The board extends the capabilities of the evaluation system by providing a connection between the asynchronous memory bus of the Blackfin proces­sor (asynchronous memory bank 3) and either a USB 2.0 or a 10/100 Mbps Ethernet device.
The following is a list of the Blackfin USB-LAN EZ-Extender interfaces.
