quality digital stereo audio development platform using the PIC32 microcontroller (MCU). It can be used for 16/24-bit stereo audio playback and recording with a sample rate of up to 48 kHz. This accessory board is powered by the USB Host and can be used with any personal computer (PC), tablet, gaming station, or mobile device that supports the USB Audio Device Class.</p> <p>The digital audio stream is transferred over USB isochronous transfers. The PIC32 USB Digital Audio Accessory Board features the PIC32 MCU, which has a USB module with Host and Device capability, SPI module with Audio Mode that supports I2S, LJ, RJ, DSP/PCM modes, and a flexible audio reference clock output generation module that can be used as time base for the external codec or Digital-to-Analog Converter (DAC).</p> <p>The PIC32 USB Digital Audio Accessory Board is preprogrammed with a USB Audio Headset application, which demonstrates audio playback and record. This demonstration can playback high quality stereo audio through headphones. It can also record audio through a microphone.</p> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Features</h3> <ul id="ctl00_ctl00_PageContent_SubPageContent_dtFeaturesText" class="prepend-top"> <li>PIC32MX250F128B MCU: 128 KB of program memory and 32 KB of RAM</li> <li>PIC32 I2S support (LJ, RJ, DSP/PCM modes supported) &ndash; all modes can be 16/24-bit</li> <li>PIC32 reference clock output for codec master clock</li> <li>Audio codec (AK4645A) with up to 48 kHz sampling rate and 16/24-bit resolution</li> <li>Supported codec-based audio processing features: <ul> <li>5-band equalizer</li> <li>Analog output mixing</li> <li>Stereo separation emphasis and wind-noise filtering</li> <li>Auto-level control</li> </ul> </li> </ul> <h3 class="toc-item xs-pb2 xs-border-bottom">Ships With</h3> <ul> <li>PIC32 USB Digital Audio Accessory 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">Application Note</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://ww1.microchip.com/downloads/en/AppNotes/01422A.pdf" target="_blank">Application Note (AN1422) for High-Quality Audio Applications Using the PIC32 (pdf)</a> </div> </div> <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="http://ww1.microchip.com/downloads/en/DeviceDoc/60001168F.pdf" target="_blank">Data Sheet for PIC32MX1XX/2XX Family (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Product Brief/Fact sheet</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/DS-52061A.pdf" target="_blank">Information Sheet for PIC32 USB Digital Audio Accessory Board (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Revision Note</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/PIC32%20USB%20Digital%20Audio%20Accessory%20Board%20PCN.pdf" target="_blank">Product Change Notice for PIC32 USB Digital Audio Accesory Board (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">Applications Library</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-archive"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/MP3%20Decoder.zip" target="_blank">MP3 Decoder (zip)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">How-To Documents</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-archive"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/High_Quality_Audio_Apps_using_PIC32.zip" target="_blank">High Quality Audio Applications using PIC32 (zip)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Sample Code</h4> <div class="attachment "> <i class="fal fa-file-archive"></i> <a href="http://ww1.microchip.com/downloads/en/AppNotes/PIC32%20USB%20Digital%20Audio%20Accesory%20Board%20Demos.zip" target="_blank">Source Code for PIC32 USB Digital Audio Accesory Board (zip)</a> </div> <div class="attachment xs-mb3"> <i class="fal fa-file-archive"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/PIC32%20USB%20Digital%20Audio%20Accesory%20Board%20Demos.zip" target="_blank">Demos for PIC32 USB Digital Audio Accesory Board (zip)</a> </div> </div> </div> <div style="clear:both;"></div> <div style="font-size: 90%;">Tags: microchip, primary_platforms, usb, mcu, development_platforms_kits, pic32</div>
