https://devzone.nordicsemi.com/f/nordic-q-a/59768/add-psram-for-nrf52840Hi, In our application, LCD will occupy 150KB RAM, and algorithm will occupy 60KB, but 52840 only has 256KB ram, so 256KB RAM is not enough for our application; We want to add qspi psram to solve ram shortage , so we need help for using qspi psram;en-USTelligent Community 13Thu, 02 Apr 2020 01:46:53 GMThttps://devzone.nordicsemi.com/thread/243066?ContentTypeID=1Thu, 02 Apr 2020 01:46:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b1a1fca6-bfe1-43a5-a163-356cac395675visionwang<p>Thanks a lot!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/242931?ContentTypeID=1Wed, 01 Apr 2020 11:39:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:061501ad-b26d-4d53-8c48-a2f2a7e0a01aEinar Thorsrud<p>Hi,</p> <p>The nRF5340 is not in mass production yet, and will not be for some time. Please contact sales if you need more details on the timeline.</p> <p>Regarding QSPI PSRAM, that is not explicitly supported or tested by Nordic, but it might work.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/242884?ContentTypeID=1Wed, 01 Apr 2020 09:33:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f12bd4a8-f6b6-44d6-a5ae-cc6288f26a85visionwang<p><span>&nbsp;Does nRF5340 have mass production?</span></p> <p><span></span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/242836?ContentTypeID=1Wed, 01 Apr 2020 06:46:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4a3bb15a-3928-4289-9746-17e8f4847747Turbo J<p>Bad idea.</p> <p>Using the nRF5340 will probably be cheaper both in board space and final product cost.</p><div style="clear:both;"></div>
