 What is the minimum low pulse required to externally reset the nRF5340? 
 I see this answer for nRF51 and this answer for nRF52 . Can I assume nRF53 will be the same 0.2 μsec? 
 Thanks,

&lt;p&gt;We&amp;#39;re flexible for our designs. We just wanted to be sure we&amp;#39;re not applying too short of a pulse.&lt;/p&gt;
&lt;p&gt;Thanks for the analysis and update!&lt;/p&gt;

&lt;p&gt;After further analyzing this topic, the latest statement from our experts&amp;nbsp;is that 1&lt;span&gt;μs is to be used as&amp;nbsp;&lt;/span&gt;the minimum reset delay.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Does this duration meet the requirements for your application? Please let us know if a shorter delay is required.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Best regards,&amp;nbsp;&lt;/p&gt;

&lt;p&gt;The recommended minimum as of now is still 1.0&lt;span&gt;μs. I will let you know when I have any update.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;Best regards,&amp;nbsp;&lt;/p&gt;

&lt;p&gt;I have checked with one of our experts on this and he is working on finding the exact duration. He recommends using 1&lt;span&gt;μs&lt;/span&gt; to be on the safe side. I will update you when I have more details regarding the minimum duration.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: nRF5340 reset pulse duration</title><link>https://devzone.nordicsemi.com/thread/322741?ContentTypeID=1</link><pubDate>Sat, 31 Jul 2021 07:00:48 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:c608b1c3-1ecf-4aaa-b7dc-4beb64bdad1c</guid><dc:creator>helsing</dc:creator><description>&lt;p&gt;Greetings Bob,&lt;/p&gt;
&lt;p&gt;I spoke to a few team members who also assumed 0.2&lt;span&gt;μs. However, I am looking for more information on this.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Best regards,&lt;/span&gt;&lt;/p&gt;
