Hi everybody.
For a personal project, I need to integrate a flash or a microSD card to store data.
As computation core I want to use nRF52811, but I'm not able to find information about allowed maximum flash or microSD card.
Can you hel me?

Hi,
What kind of interface does the flash have? QSPI or SPI? The nRF52810 does not support integrating external flash into it's memory space, you would have write to it as any other external unit. The nRF52840 supports "expanding the memory" by using the execute in place feature which lets the CPU execute program code directly from external flash. It does however not support writing to the memory.

The target uC has only a standard SPI interface. I don't need to boot or execute code directly form external flash. I only need to store a signal acquired from ADC.
In this respect, can you confirm that I can surely use a flash?
You mean that the flash has a SPI interface? Then you can use the SPI interface on the nRF52811 to write to the external flash.
