such as battery backup, RTC and anti-tamper features. The two current channels are measured with the MCP3911 device and the voltage channel is measured with the 12-bit SAR ADC integrated in the microcontroller. This design has two sensors for the current measurements: a current transformer and a shunt. </span></p> <p><span>The PIC18F85K90 microcontroller directly drives the LCD and communicates via UART with the MCP2200, offering an isolated USB connection for meter calibration and access to the device power calculations. The system calculates active and reactive energy, active, reactive and apparent power, power factor, RMS current, RMS voltage and the line frequency. The Microchip Energy Meter Software is used to calibrate and monitor the system.</span></p> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Features</h3> <ul id="ctl00_ctl00_PageContent_SubPageContent_dtFeaturesText" class="prepend-top"> <li>Rated 5(60)A 220V 3200 imp/kWh IEC62053-22 Class 0.5 Energy Meter</li> <li>Calculates active and reactive energy, active, reactive and apparent power, power factor, RMS current, RMS voltage and the line frequency</li> <li>Anti-tamper monitoring including neutral monitoring, current circuit reversal, magnetic field disturbance and cover opening detection</li> <li>Microchip Energy Meter Software is used to calibrate and monitor the system</li> <li>Calibration can be done in closed loop or open loop</li> <li>Low-cost capacitive-based power supply design</li> </ul> <h3 class="toc-item xs-pb2 xs-border-bottom">Ships With</h3> <ul> <li>Reference Design 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 "> <i class="fal fa-file-pdf"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/39957d.pdf" target="_blank">Datasheet For PIC18F87K90 Family (pdf)</a> </div> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/20002286C.pdf" target="_blank">Datasheet For MCP3911 (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Tips and Tricks</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.microchip.com/wwwAppNotes/AppNotes.aspx?appnote=en557898" target="_blank">Design Tips for the MCP3911 (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">User Manual/Guide</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/52097A.pdf" target="_blank">User Guide For MCP3911 and PIC18F85K90 Reference Design (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://ww1.microchip.com/downloads/en/DeviceDoc/ARD00385_BOM.pdf" target="_blank">BOM for MCP3911 and PIC18F85K90 Energy Meter (ARD00385) (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Design Package</h4> <div class="attachment "> <i class="fal fa-file-archive"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/Single%20Phase%20Energy%20Meter%20(ARD00385)%20Firmware.zip" target="_blank">Firmware for MCP3911 and PIC18F85K90 Energy Meter (ARD00385) (zip)</a> </div> <div class="attachment xs-mb3"> <i class="fal fa-file-archive"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/ARD00385_Gerbers.zip" target="_blank">Gerbers for MCP3911 and PIC18F85K90 Energy Meter (ARD00385) (zip)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Design Techniques</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-archive"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/ARD00385_GUI.zip" target="_blank">Software for MCP3911 and PIC18F85K90 Energy Meter (ARD00385) (zip)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Schematics/Layout Files</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://ww1.microchip.com/downloads/en/DeviceDoc/ARD00385_Rev4_Schematic.PDF" target="_blank">Schematics for MCP3911 and PIC18F85K90 Energy Meter (ARD00385) (pdf)</a> </div> </div> </div> <div style="clear:both;"></div> <div style="font-size: 90%;">Tags: afemxfe, microchip, Energy Meter Reference Design, MCP3911 + PIC18F85K90, data_conversion, analog_demo_boards</div>
