It has nRF52833 controller with external crystal oscillator of 32MHz. I would like to know the operating clock frequency of the nRF52833. Could you please share the details?en-USTelligent Community 13Thu, 27 Apr 2023 07:17:21 GMThttps://devzone.nordicsemi.com/thread/422643?ContentTypeID=1Thu, 27 Apr 2023 07:17:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a6814c95-122e-4e4f-b3da-c5e94400d7acPriyanka<p>Hi Nadeem,</p> <p>If you are asking for the CPU clock frequency of the nRF52833, it is fixed at 64MHz and you cannot change it to higher or lower frequencies.</p> <p><a href="https://infocenter.nordicsemi.com/topic/ps_nrf52833/cpu.html?cp=5_1_0_3_0_2#topic">https://infocenter.nordicsemi.com/topic/ps_nrf52833/cpu.html?cp=5_1_0_3_0_2#topic</a>&nbsp;</p> <p><a href="https://infocenter.nordicsemi.com/topic/ps_nrf52833/clock.html?cp=5_1_0_4_3_0#concept_rp5_fgp_bs">https://infocenter.nordicsemi.com/topic/ps_nrf52833/clock.html?cp=5_1_0_4_3_0#concept_rp5_fgp_bs</a>&nbsp;</p> <p>Best Regards,</p> <p>Priyanka</p><div style="clear:both;"></div>
