Can we use SPI NAND flash having 166Mhz/104Mhz clock frequency with nRF52840 which supports upto 8Mbps data transfer speed on SPIM0-2. and upto 32Mbps on SPIM3 peripheral?

Hi,

It is because it is not supported. As stated in this other case, What about the actual FLASH support in nRF Connect SDK? , you can try to add the driver support as a third party library to the SDK, but we give no guarantee that it will work.

Kind regards,
Andreas

It's not recommended to use because of limitation in SDK of no support for NAND flash or is there any other reason of it? One can always add the driver support as a thrid party library to SDK? Is there any other limitation or concern?

Hi,

Unfortunately we don't support NAND flash in our SDKs. We recommend you to use the supported NOR type instead.

Kind regards,
Andreas

Hi,

the datasheet of the flash chip says any clock frequency between DC and 104MHz will work. So 8 and 32 MHz would be OK.

Best Regards
