 What would we expect the INFO.VARIANT FICR register&amp;#39;s value to be with, for example, an nRF52811-CAAA-R7 vs. an nRF52811-CAAA-R7-B? 
 Right now I am seeing &amp;quot;AAA0&amp;quot; as the value in INFO.VARIANT--does this correspond to nRF52811-CAAA-R7?

&lt;p&gt;No worries. I had inquired internally and it seems the one with -B postfix is Revision 2 chips with approtect fix: &lt;a title="https://docs.nordicsemi.com/bundle/in/resource/in_151_v1.0.1.pdf" href="https://docs.nordicsemi.com/bundle/IN/resource/in_151_v1.0.1.pdf" rel="noopener noreferrer" target="_blank"&gt;https://docs.nordicsemi.com/bundle/IN/resource/in_151_v1.0.1.pdf&lt;/a&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;The other is pre-approtect fix chips (revision 1): &lt;a title="https://docs.nordicsemi.com/bundle/comp_matrix_nrf52811/page/comp/nrf52811/nrf52811_ic_revision_overview.html" href="https://docs.nordicsemi.com/bundle/comp_matrix_nrf52811/page/COMP/nrf52811/nrf52811_ic_revision_overview.html" rel="noopener noreferrer" target="_blank"&gt;https://docs.nordicsemi.com/bundle/comp_matrix_nrf52811/page/COMP/nrf52811/nrf52811_ic_revision_overview.html&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;From the Ordering Information in the P.S, you can see how the labelling on a nRF52811SoC would be:&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1730366305143v1.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;For eg, if on the chip it is N52811CAAAA02020JG, then the VV = AA &amp;amp; HP = A0. Then the INFO.VARIANT would be AAA0.&lt;/p&gt;
&lt;p&gt;So it would depend on the SoC and you can find them out by looking at the marking on the chip.&lt;/p&gt;
&lt;p&gt;I don&amp;#39;t have a R7 &amp;amp; R7-B with me at hand, but I can look around and check this internally.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Regards,&lt;/p&gt;
