power cycling effect on Mean time to Failurehttps://devzone.nordicsemi.com/f/nordic-q-a/95316/power-cycling-effect-on-mean-time-to-failureHello, I am using the nrf52 for development purposes, during the development I need to power cycle the device approximately ~1000 times, no flash writes in between. Does this effect the mean time to failure? Does this effect the lifespan of the deviceen-USTelligent Community 13Tue, 03 Jan 2023 14:22:26 GMTRE: power cycling effect on Mean time to Failurehttps://devzone.nordicsemi.com/thread/402997?ContentTypeID=1Tue, 03 Jan 2023 14:22:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:24ebc893-aefe-4fc5-9a9c-2d81af712f88Simonr<p>Hi Michael</p> <p>No, if the power cycles doesn&#39;t affect the flash there shouldn&#39;t be a noteworthy affect to the nRF52832 lifespan or &quot;mean time to failure&quot;. The factors that do impact the lifespan is mainly the supplied voltage, the storage/operating temperature and the amount of flash write/erase cycles done on the device.
