Where to get NRF52832QFAB chips with 256kB flash?

[yaoCheng]

Hello,

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. If I understand the Errata correctly, there are two revisions of NRF52832-QFAB:

 1.  NRF52832QFAB Rev1, labeled with „NRF52832 QFAB-B00“, has 512kB flash

 2. NRF52832QFAB Rev2, labeled with „NRF52832 QFAB-E00“, has 256kB flash

I ordered some  NRF52832-QFAB chips from different sources, unfortunately, they all have 512kB flash.

So my question is, where can I get some NRF52832 QFAB chips which certainly have 256kB flash?

Hi,

This is due to erratum 163 as you write, which says that Code and RAM size fields in FICR do not match chip specification. 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.

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 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 upper 256 kB has not been through production testing and may or may not work.
