reference design, built to authenticate peripherals to Xilinx&reg; FPGAs. Using the provided example code, the FPGA executes a challenge-response sequence with the DS28C22 to ensure the authenticity of a module, peripheral, or subsystem. The DS28C22 communicates on an I2C bus, providing a standard communication interface. <br /><br />The MAXREFDES43# is equipped with a Pmod&trade; connector for immediate testing using an Avnet ZedBoard&trade;. The simplicity of this design enables rapid adoption into any peripheral requiring security.<br /><br /><strong>Applications:</strong><br /> <ul> <li>Crypto-strong authentication</li> <li>Fast performance with hardware acceleration</li> </ul> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Features</h3> <ul> <li>SHA-256 authentication</li> <li>I²C interface</li> <li>Example source code</li> <li>Pmod-compatible form factor</li> </ul> <h3 class="toc-item xs-pb2 xs-border-bottom">Ships With</h3> <ul> <li>Board</li> </ul> <div id="devtool-required-devtools-section" class="xs-hide"> <h3 class="toc-item xs-pb2 xs-mb1 xs-border-bottom">Required Tools</h3> <div id="devtool-required-devtools-content"></div> </div> <div id="devtool-accessory-devtools-section" class="xs-hide"> <h3 class="toc-item xs-pb2 xs-mb1 xs-border-bottom">Accessory Tools</h3> <div id="devtool-accessory-devtools-content"></div> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Documents</h3> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Data Sheet</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="https://datasheets.maximintegrated.com/en/ds/DS28C22.pdf" target="_blank">DS28C22 DeepCover Secure Memory with I2C SHA-256 and 3Kb User EEPROM (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Quick Start Guide</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://pdfserv.maximintegrated.com/en/an/UG6136.pdf" target="_blank">MAXREFDES43# ZedBoard Quick Start Guide (pdf)</a> </div> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Downloads</h3> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Bill of Materials</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.maximintegrated.com/design/tools/appnotes/6134/MAXREFDES43_BOM_RD.pdf" target="_blank">Bill of Materials (BOM) for MAXREFDES43 (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Design Package</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-archive"></i> <a href="http://www.maximintegrated.com/design/tools/appnotes/6134/MAXREFDES43_ALL_FILES.zip" target="_blank">Design Files for MAXREFDES43 (zip)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Schematics/Layout Files</h4> <div class="attachment "> <i class="fal fa-file-pdf"></i> <a href="http://www.maximintegrated.com/design/tools/appnotes/6134/MAXREFDES43_SCH_RD.pdf" target="_blank">Schematic for MAXREFDES43 (pdf)</a> </div> <div class="attachment "> <i class="fal fa-file-pdf"></i> <a href="http://www.maximintegrated.com/design/tools/appnotes/6134/MAXREFDES43_LAYOUT_RD.pdf" target="_blank">PCB Layout for MAXREFDES43 (pdf)</a> </div> <div class="attachment xs-mb3"> <i class="fal fa-file-archive"></i> <a href="http://www.maximintegrated.com/design/tools/cad-layout/gerber/MAXREFDES43_GERBER_RD.ZIP" target="_blank">PCB Gerber for MAXREFDES43 (zip)</a> </div> </div> </div> <div style="clear:both;"></div> <div style="font-size: 90%;">Tags: fpga, DS28C22, SHA-256, mcu, maxim, development_platforms_kits, reference_designs</div>
