 I am investigating an alternative to an implantable device that currently uses NFC. 
 The device range would only be about 3m and the data would only be transmitted for a few minutes each day. The big requirement is that the device needs to work</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Tue, 08 May 2018 08:28:26 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/34125/ultra-low-power-implantable-reduced-range" /><item><title>RE: ultra low power implantable, reduced range</title><link>https://devzone.nordicsemi.com/thread/131308?ContentTypeID=1</link><pubDate>Tue, 08 May 2018 08:28:26 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:9c02447d-f7d2-4c00-94bd-a0105bf318ca</guid><dc:creator>bjorn-spockeli</dc:creator><description>&lt;p&gt;If you&amp;#39;re looking for a small SoC for a medical device then I would recommend looking at the nRF52810 SoC, &lt;a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52/dita/nrf52/chips/nrf52810.html?cp=2_2"&gt;here&lt;/a&gt;&amp;nbsp;is the link to the Product Specification.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;The sleep current of the nRF52810 is very low, only 1.5uA when the RTC is waking up the chip at a periodic interval( configurable). Current consumption for other sleep configurations can be found &lt;a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52810.ps/_tmp/gluon/autodita/CURRENT/parameters.id_current_sleep.html?cp=2_2_0_4_1_0_2"&gt;here&lt;/a&gt;.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;In terms of the transmit and receive paramenters, transmitting @ -40 dBm output power will give you a typical current consumption of 3.4mA.&lt;/p&gt;
&lt;p&gt;You can see a list of the Radio TX/RX current consumption in various configurations on &lt;a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52810.ps/_tmp/gluon/autodita/CURRENT/parameters.id_current_radio.html?cp=2_2_0_4_1_0_1"&gt;this&lt;/a&gt;&amp;nbsp;Infocenter page&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
