Product details
Overview
AW611HN/A1AK from NXP Semiconductors is an AEC-Q100 Grade 2/3 qualified automotive Wi-Fi 6 (802.11ax) and Bluetooth 5.2 combo IC integrating dual-band 2.4/5 GHz 1×1 Wi-Fi with integrated PA/LNA, independent Bluetooth/LE subsystem, SDIO 3.0 host interface, and I2S/PCM audio interfaces - deployed in in-vehicle infotainment (IVI), telematics, and two-wheeler ECUs.
For engineers reviewing the AW611HN/A1AK datasheet, AW611HN/A1AK pinout, AW611HN/A1AK application, or AW611HN/A1AK equivalent, key selection criteria include automotive qualification grade, integrated RF front-end elimination, Wi-Fi 6 MU-MIMO/OFDMA support, Bluetooth LE isochronous channels for LE Audio, and coexistence-ready dual-antenna configuration capability.
Technical Context
The AW611HN/A1AK implements two physically isolated protocol stacks: a full 802.11ax MAC/baseband/radio subsystem supporting 20/40/80 MHz bandwidths, MCS0–11, HE SU/MU/TB PPDU formats, and DFS radar detection; and a concurrent Bluetooth 5.2 baseband with BDR/EDR, LE 5.3 features including 2 Mbps, Long Range, Advertising Extensions, and isochronous channels - both subsystems feature dedicated CPUs and memory for real-time, independent processing.
Hardware-level coexistence is enabled via shared antenna resources and configurable SPDT switch/diplexer routing between Wi-Fi 2.4 GHz/BT Rx, Wi-Fi 5 GHz Tx/Rx, and BT Tx paths; host connectivity uses SDIO 3.0 (up to SDR104, 208 MHz) for Wi-Fi and high-speed UART (≤3 Mbps) for Bluetooth, while audio is handled through time-multiplexed I2S/PCM interfaces supporting mono/dual-channel voice and WBS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Wi-Fi Standard | IEEE 802.11ax (Wi-Fi 6) 1×1 SU/MU-MIMO/OFDMA, backward compatible with 802.11ac/n/a/g/b - enables higher throughput, lower latency, and improved multi-user efficiency in dense vehicle networks. |
| Bluetooth Version | Bluetooth 5.2 + LE 5.3 - supports dual WBS links, isochronous channels for LE Audio, 2 Mbps data rate, Long Range, and enhanced privacy/security. |
| RF Bands | 2.4 GHz (channels 1–13) and 5 GHz (channels 36–177, plus UNII-2e/3/4 extensions) - covers global regulatory domains including FCC, ETSI, and MIC. |
| Host Interfaces | SDIO 3.0 (4-bit/1-bit, SDR104 up to 208 MHz) for Wi-Fi; UART up to 3 Mbps for Bluetooth - eliminates need for external bridge ICs and simplifies host processor integration. |
| Audio Interfaces | I2S/PCM shared pins with 8/16-bit slot support, 4.096/2.048/2 MHz clock options, mono/dual-channel modes - directly connects to ADC/DAC or audio SoCs without external codecs. |
| Automotive Qualification | AEC-Q100 Grade 2 (−40 °C to +105 °C) and Grade 3 (−40 °C to +85 °C) - validated for under-hood and cabin-mounted automotive ECU deployment. |
| Integrated RF Front End | On-die PA, LNA, and Tx/Rx switch for both 2.4 GHz and 5 GHz bands - removes external FEM, reduces BOM count by ≥5 components, and improves RF matching stability. |
Pinout & Package
AW611HN/A1AK is housed in a 7.0 mm × 7.0 mm × 0.85 mm 64-pin QFN package with wettable flanks and 0.4 mm pitch. Pin functions are defined per NXP's official AW611 reference design and application schematics (Figures 1–2), with dedicated groups for SDIO, UART, I2S/PCM, GPIO/LED, power, and RF antenna routing.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Wi-Fi 6 + Bluetooth combo applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IW611 | Non-automotive variant; lacks AEC-Q100 qualification and Grade 2/3 thermal specs; identical Wi-Fi/Bluetooth IP and interface set. | Targeted at industrial gateways and consumer routers - not suitable for automotive production due to missing stress testing and failure-in-time (FIT) data. | Select IW611 only for prototyping or non-automotive volume deployments where cost sensitivity outweighs qualification requirements. |
| AW612HN/A1AK | Tri-radio extension adding IEEE 802.15.4 (Thread/Zigbee) PHY/MAC; same package, pin-compatible, but larger die and higher power consumption. | Required when vehicle architecture mandates concurrent Wi-Fi, Bluetooth, and low-power mesh networking - e.g., smart EV charging stations with local energy management. | Choose AW612HN/A1AK if 802.15.4 interoperability is mandatory; otherwise AW611HN/A1AK delivers optimal cost/power/performance balance for pure Wi-Fi+BT use cases. |
Compared with IW611, AW611HN/A1AK adds automotive-grade reliability, extended temperature operation, and certified EMC behavior - essential for Tier 1 ECU integration. Compared with AW612HN/A1AK, it reduces power draw by ~18% and simplifies RF layout by removing 802.15.4 antenna path, making it ideal for cost- and space-constrained IVI modules.

FAQ
What automotive qualification grades does the AW611HN/A1AK support?
The AW611HN/A1AK is qualified to AEC-Q100 Grade 2 (−40 °C to +105 °C) and Grade 3 (−40 °C to +85 °C) standards, enabling deployment in both engine-bay-proximate and cabin-mounted electronic control units. This dual-grade qualification is verified per NXP's official product brief Rev. 1 (16 May 2023) and allows a single BOM to serve multiple vehicle zones without redesign. The AW611HN/A1AK undergoes accelerated stress testing including HTOL, TC, and ESD per AEC-Q100 requirements.
Does the AW611HN/A1AK require an external RF front-end module (FEM)?
No, the AW611HN/A1AK integrates a complete 2.4 GHz and 5 GHz Wi-Fi radio with on-die power amplifier (PA), low-noise amplifier (LNA), and transmit/receive switch - eliminating the need for external FEMs. This integration reduces bill-of-materials count, PCB footprint, and RF calibration complexity. The AW611HN/A1AK achieves full regulatory compliance (FCC/CE/MIC) using only passive matching networks and antenna tuning components, as confirmed in NXP's AW611_PB application diagrams.
Which Bluetooth audio profiles and voice features are supported by the AW611HN/A1AK?
The AW611HN/A1AK supports HFP (Hands-Free Profile), A2DP (Advanced Audio Distribution Profile), and dual Wideband Speech (WBS) links for HD voice. It implements hardware-accelerated SCO/eSCO with PPEC speech enhancement and full support for Bluetooth LE isochronous channels required for LE Audio. These capabilities are documented in Sections 3.1 and 3.2 of the AW611_PB product brief, and the AW611HN/A1AK delivers them without requiring host-side LC3 codec implementation.
What host processor interfaces does the AW611HN/A1AK provide for Wi-Fi and Bluetooth connectivity?
The AW611HN/A1AK provides SDIO 3.0 (4-bit/1-bit, SDR104 up to 208 MHz) for Wi-Fi host communication and high-speed UART (up to 3 Mbps with hardware flow control) for Bluetooth HCI transport. Both interfaces are electrically and logically independent, allowing simultaneous operation. The AW611HN/A1AK does not require USB or PCIe bridges, reducing host SoC interface complexity and driver development effort - details are specified in Sections 2.8 and 3.3 of the official product brief.
Can the AW611HN/A1AK operate in both single-antenna and dual-antenna configurations?
Yes, the AW611HN/A1AK supports both configurations: single-antenna mode uses an internal diplexer to share one antenna between 2.4 GHz Wi-Fi/BT Rx and 5 GHz Wi-Fi Tx/Rx, while dual-antenna mode assigns dedicated antennas to 2.4 GHz and 5 GHz bands. Figure 1 and Figure 2 in the AW611_PB document illustrate both topologies, and the AW611HN/A1AK's internal SPDT switch and coexistence logic automatically manage RF path selection without host intervention.
