Internal Flash as a Non volatile Memory for user datahttps://devzone.nordicsemi.com/f/nordic-q-a/15715/internal-flash-as-a-non-volatile-memory-for-user-dataCurrently we are considering whether we should use external Flash Memory or NRF52 Internal Flash. External Flash memory has a lot of drawback in comparsion with internal flash. -Board Space, cost, lead time, software complication, power consumptionen-USTelligent Community 13Mon, 15 Aug 2016 08:45:22 GMTRE: Internal Flash as a Non volatile Memory for user datahttps://devzone.nordicsemi.com/thread/59993?ContentTypeID=1Mon, 15 Aug 2016 08:45:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b57ce384-1da3-43ec-9cab-434be8a736bcPetter Myhre<p>The nRF52832 has an endurance of 10000 write/erase cycles, and a minimum retention of 10 years.

Depending on the use cases you have a lot of additional software is required to work around this possibility.</p> <p>Adrian</p><div style="clear:both;"></div>
