6 Software stack
This section details the partitioning of the TCP/IP networking stack and the IEEE 802.11 Wi-Fi stack across
the host MCU and nRF7002.
This description is based on Zephyr™ TCP/IP networking stack and an nRF5340 host MCU. However, the
partitioning applies equally to other operating systems and host MCUs supporting a compatible SPI/QSPI.

Figure 5: Network stack architecture
The TCP/IP networking stack and Wi-Fi driver execute on the host MCU (for example, nRF5340) and
communicate with the MAC layer on nRF7002 through SPI/QSPI. The Wi-Fi driver presents control and
data interfaces (Control IF/Data IF) to the TCP/IP networking stack.
