 I have a couple of questions regarding the nRF52811. 
 
 1. What&amp;#39;s the boot time of the nRF52811 from the power on to call the main() function of the bootloader? 
 2. What is the minimum Voltage required to perform the above operation?</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Fri, 11 Nov 2022 23:05:08 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/93786/nrf52811-boot-time" /><item><title>RE: nRF52811 Boot time</title><link>https://devzone.nordicsemi.com/thread/395402?ContentTypeID=1</link><pubDate>Fri, 11 Nov 2022 23:05:08 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:d27302e6-428c-481d-96be-68975343b2c0</guid><dc:creator>Hieu</dc:creator><description>&lt;p&gt;Hi agl,&lt;/p&gt;

&lt;p&gt;The theoretical&amp;nbsp;time since power is supplied until the CPU runs is described in Section 5.3.10.1 of the &lt;a href="https://infocenter.nordicsemi.com/topic/ps_nrf52811/keyfeatures_html5.html?cp=4_4_0"&gt;nRF52811 Product Specification&lt;/a&gt;, also available online &lt;a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf52811%2Fpower.html&amp;amp;cp=4_4_0_4_2_9_0&amp;amp;anchor=unique_279794834"&gt;here&lt;/a&gt;.&lt;br /&gt;That is not technically the time until main() is execute, but it&amp;nbsp;is as far as specification go.&lt;/p&gt;
&lt;p&gt;A&amp;nbsp;measurement of a real&amp;nbsp;nRF52840 case is discussed in this thread, if you are interested:&amp;nbsp;&lt;span&gt;&amp;nbsp;&lt;a href="https://devzone.nordicsemi.com/f/nordic-q-a/82799/nrf52840-startup-time"&gt;nRF52840 startup time&lt;/a&gt;&amp;nbsp;&lt;/span&gt;&lt;/p&gt;
[quote user=""]2. What is the minimum Voltage required to perform the above operation?[/quote]
&lt;p&gt;It should be the same as the device&amp;#39;s minimum operating voltage range, 1.7V.&lt;/p&gt;
&lt;p&gt;&lt;span&gt;I&amp;#39;m a little curious, why are you interested in such information?&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;By the way, please remember that with a public question, don&amp;#39;t rule out the chance that someone from the community can help :)&lt;/p&gt;
