https://devzone.nordicsemi.com/f/nordic-q-a/34524/where-to-get-nrf52832qfab-chips-with-256kb-flashHello, I would like to test my code on a NRF52832-QFAB chip with 256kB chip to see whether my code fits into the 256kB flash variant. According to nRF52832 Rev 1 Errata [163], a NRF52832-QFAB chip has either 256kB or 512kB flash.

This erratum is fixed for revision 2 chips, so you will not see this if you get the latest revision chips. You have to talk to your distributor if you want to be sure that you get revision 2 chips.</p> <p>Please not that this does not have any practical consequence as long as you make sure to not use flash above 256 kB on your&nbsp;NRF52832-QFAB project(s). Please note that even if you find that some NRF52832-QFAB actually has 512 kB flash, you should not use it. The&nbsp;upper 256 kB has not been through production testing and may or may not work.</p><div style="clear:both;"></div>
