Memory requirements for Wi-Fi applications in Station mode

Code and RAM memory footprint requirements differ depending on the selected platform and the application example.

The following tables list memory requirement values for selected Wi-Fi® samples supporting Station mode.

Footprint values are provided in kilobytes (KB).

The following table lists memory requirements for sample running on the nRF52840 DK (nrf52840dk/nrf52840).

Sample	Total ROM	Wi-Fi driver ROM	nRF70 FW patch ROM	WPA supplicant ROM	Total RAM (incl. static heap)	Wi-Fi driver RAM	WPA supplicant RAM
Station	502	51	69	180	253	164	11

The following table lists memory requirements for samples running on the nRF7002 DK (nrf7002dk/nrf5340/cpuapp).

Note

The footprint of the networking samples for the Zephyr image is derived from the board target with Cortex-M Security Extensions enabled (*/ns variant).
