https://devzone.nordicsemi.com/f/nordic-q-a/45953/identifying-nrf52832-chip-revision-from-ficr-registerHello, I&#39;ve got an nRF52832 embedded in a module (Telit RE866). As such, I can&#39;t see the markings on the chip and have to resort to reading the FICR registers to identify the hardware revision. Here are the results: INFO.PART = 0x52832 INFO.VARIANTen-USTelligent Community 13Tue, 09 Apr 2019 18:54:26 GMThttps://devzone.nordicsemi.com/thread/181166?ContentTypeID=1Tue, 09 Apr 2019 18:54:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:da58e4c0-771c-45ae-8c22-599fe20d5ac6amrbekhit<p>Thanks for the suggestion - not a bad idea. I ended up stepping through the execution of SystemInit on the device and found that errata 31, 36, 66, and 108 were executed. Looking at the various errata documents, this would mean the device is probably either Engineering C, Revision 1 or Revision 2.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/181001?ContentTypeID=1Tue, 09 Apr 2019 11:09:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d060c05d-d2c2-4a32-9e95-4870bdea53c7Kenneth<p>Hi,</p> <p>Unfortunately there is no place you can find this directly, however if you open the system_nrf52.c you can reverse engineer how to identify the hardware revision by comparing to the individual Errata document for the various issue and variants.</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
