NRF7001-QFAA-R

Overview

The NRF7001-QFAA-R is a Wi-Fi 6 companion IC from Nordic Semiconductor, designed for low-power IoT applications. It operates exclusively in the 2.4 GHz band and supports IEEE 802.11b/g/n/ax standards. The device features a single spatial stream with 20 MHz channel bandwidth, supporting up to 86 Mbps PHY throughput using 64 QAM (MCS7). Key Wi-Fi 6 capabilities include OFDMA and BSS coloring. It connects to host processors via SPI or Quad SPI interfaces and includes Target Wake Time (TWT) support for power efficiency.

Feature Summary

• Supports Wi-Fi 6 (802.11ax) and legacy 802.11b/g/n standards for robust connectivity
• Enables extended battery life through integrated Target Wake Time (TWT) power-saving mechanisms
• Provides advanced security features to protect user data during transmission
• Facilitates coexistence with Bluetooth Low Energy, Thread, and Zigbee protocols

Applications

• Smart home devices requiring single-band Wi-Fi connectivity
• Industrial automation sensors and controllers
• Battery-powered IoT endpoints needing long operational lifespan
• Smart city infrastructure nodes

Procurement Notes

Verify that the specific application design strictly requires 2.4 GHz operation only, as this component lacks 5 GHz capability found in the nRF7002 series. Confirm host processor compatibility with SPI or QSPI interfaces before integration. Ensure firmware development utilizes the nRF Connect SDK for proper driver support and feature activation. Check mechanical constraints against the 48-VFQFN package dimensions for PCB layout accuracy.

Selection Notes

Select this component when cost optimization is prioritized over dual-band flexibility. It serves as a direct alternative to the nRF7002 for designs where 5 GHz spectrum access is unnecessary. Ideal for developers already utilizing Nordic nRF52 or nRF53 series SoCs who require seamless Wi-Fi integration without increasing bill of materials costs significantly compared to dual-band options.

Part Context

The NRF7001-QFAA-R belongs to the nRF70 series of Wi-Fi 6 companion ICs. It complements the dual-band nRF7002 by offering a specialized single-band solution. This series integrates RF front-end technology with Nordic's low-power expertise, targeting the growing market for secure, efficient, and connected IoT devices across residential and industrial sectors.

Replacement Considerations

The nRF7002-QFAA-R is a confirmed substitute part number offering dual-band (2.4 GHz and 5 GHz) functionality. While pin-compatible and software-compatible via the nRF Connect SDK, it incurs higher material costs. No other public confirmed substitutes exist for this specific single-band configuration.
