In all reference designs of LS1046A and LS1028 the signals are pulled up.</P><P>Since these signals are LOW active. Wont this trigger a tamper right away?</P><P>Kind regards,</P><P>Remco</P> Mon, 05 Oct 2020 06:54:49 GMT https://community.nxp.com/t5/Layerscape/LS1046A-TA-TMP-DETECT-B/m-p/1162749#M6738 sinu52 2020-10-05T06:54:49Z https://community.nxp.com/t5/Layerscape/LS1046A-TA-TMP-DETECT-B/m-p/1162872#M6739 <P>The AN5252 means the following connection circuit:<span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Tamper.jpg" style="width: 513px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/126750i38F56CE434DDE13A/image-dimensions/513x170?v=v2" width="513" height="170" role="button" title="Tamper.jpg" alt="Tamper.jpg" /></span></P> Mon, 05 Oct 2020 10:30:13 GMT https://community.nxp.com/t5/Layerscape/LS1046A-TA-TMP-DETECT-B/m-p/1162872#M6739 ufedor 2020-10-05T10:30:13Z
