* ### Features

  **nRF7002**

  nRF7002 Wi-Fi® 6 companion IC with integrated RF

  * IEEE 802.11 ax and IEEE 802.11 a/b/g/n/ac support
  * Dual-band 2.4 GHz and 5 GHz operation
  * SPI or QSPI host interface
  * 3-wire or 4-wire coexistence interface

  **Wi-Fi® 6**

  IEEE 802.11 a/b/g/n (Wi-Fi® 6), dual-band Wi-Fi® (2.4 GHz / 5 GHz)

  * 20 MHz channel bandwidth
  * 1x1 SISO operation
  * PHY data rate up to 86 Mbps (MCS7)
  * Supports Target Wake Time (TWT), OFDMA, and BSS Coloring
  * Supports Station, Wi-Fi® Direct, and SoftAP operation modes
  * Supports simultaneous operation of multiple Wi-Fi® roles; SoftAP operation is limited to Wi-Fi® 4

  **Host interface**

  * Designed for operation with an external MCU, MPU or SoC host
