https://devzone.nordicsemi.com/f/nordic-q-a/34043/nrf52832qfaa-flash-sizeHi, I am using a chip labeled with &quot;N52832 QF ABB0 1717AQ&quot;. According to its specification, this chip should have 256kB flash. However, nRFgo Studio shows that its size is actually 512kB. So how large is the flash size of &quot;NRF52832 QFAB&quot; varianten-USTelligent Community 13Fri, 04 May 2018 07:42:00 GMThttps://devzone.nordicsemi.com/thread/130936?ContentTypeID=1Fri, 04 May 2018 07:42:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:44828f4f-f5d7-47ca-bef5-7e7a770b79b5bjorn-spockeli<p><a href="https://devzone.nordicsemi.com/members/yaocheng">yaoCheng</a>: No, it is indeed a QFAB variant.
