 Section 7.3 of the data sheet states that NFC can be used in any power configurations. 
 But Table 139 states that the NFC feature only works in configuration 5</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Mon, 23 Jul 2018 13:17:02 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/36686/nfc-and-power-supply-via-vddh" /><item><title>RE: NFC and power supply via VDDH</title><link>https://devzone.nordicsemi.com/thread/140987?ContentTypeID=1</link><pubDate>Mon, 23 Jul 2018 13:17:02 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:d1f6d1c6-8134-4b7a-81a7-b4bdcc6e240c</guid><dc:creator>Andreas</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Correct, NFC can be used in any configuration. The &amp;#39;no&amp;#39; in table 139 is simply pointing out that the NFC antenna is not included in the design configurations.&amp;nbsp;You can mix and match, including the NFC antenna the NFC can be used regardless of&amp;nbsp;supply configuration.&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;

&lt;p&gt;thanks for pointing this out. So we can use NFC with VDDH configurations.&amp;nbsp;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: NFC and power supply via VDDH</title><link>https://devzone.nordicsemi.com/thread/140934?ContentTypeID=1</link><pubDate>Mon, 23 Jul 2018 08:32:03 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:70594a01-0f7c-482c-af55-871b9f232bc8</guid><dc:creator>PaKa</dc:creator><description>&lt;p&gt;Please read the entire section, points to notice:&lt;/p&gt;
&lt;p&gt;Note: This is not a complete list of configurations, but all required circuitry is shown for further&lt;br /&gt;configurations.&lt;/p&gt;
&lt;p&gt;and:&lt;/p&gt;
&lt;p&gt;NFC can be used in any configuration.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
