https://devzone.nordicsemi.com/f/nordic-q-a/20776/replace-32-mhz-crystal-with-8-mhz-crystal-on-the-nrf52832Hi, i was just wondering as we dont need the high clock rate whether its possible to run the nrf52832 with less than 64 Mhz by replacing the 32 mhz crystal with a different crystal with a lower clock frequency? thank you :)en-USTelligent Community 13Fri, 24 Mar 2017 18:11:41 GMThttps://devzone.nordicsemi.com/thread/81137?ContentTypeID=1Fri, 24 Mar 2017 18:11:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6f8b52e4-bda5-4b2e-863e-24ae68d6e882uC_newbie<p>Thank you very much!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/81136?ContentTypeID=1Fri, 24 Mar 2017 17:13:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8f30a5c3-bf9c-413f-82f1-18bfffbf30dbSigurd<p>Hi,</p> <p>You can only run the CPU at 64MHz. Using a 64MHz clock will execute your tasks faster and overall you wont save power reducing the clock speed. It is therfore not implemented any options to use a different clock frequency for the CPU. If you are using BLE, you have to use an external 32 MHz crystal with a frequency tolerance of max 40 ppm.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/81135?ContentTypeID=1Fri, 24 Mar 2017 15:59:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d5b60234-8833-438f-a116-8a3885e074c7uC_newbie<p>We will in the future, yes. It is needed for that? (have not yet looked into BLE in detail) If so then my this settles this, haha.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/81134?ContentTypeID=1Fri, 24 Mar 2017 15:35:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8c5ff9f0-8660-4c31-97db-4e914e29767dDaniel Wang<p>You don&#39;t use BLE?</p><div style="clear:both;"></div>
