Product details
Overview
IW416HN/A1IMP from NXP Semiconductors is a dual-band 1×1 Wi-Fi 4 (802.11n) and Bluetooth 5.2 Combo SoC supporting simultaneous 2.4 GHz/5 GHz Wi-Fi operation at up to 150 Mbit/s and Bluetooth LE 2 Mbps, Long Range, and PAST. It integrates TX PAs, RX LNAs, and RF switches for single- or dual-antenna configurations and targets industrial IoT gateways requiring coexistence-aware wireless connectivity.
For engineers reviewing the IW416HN/A1IMP datasheet, IW416HN/A1IMP pinout, IW416HN/A1IMP application, or IW416HN/A1IMP equivalent, this page delivers verified package mapping (HVQFN68), confirmed industrial temperature range (−40 to +85°C), SDIO 3.0 + UART host interfaces, integrated coexistence hardware (PTA/WCI-2), and real-world use-case validation for smart city infrastructure and asset tracking.
Technical Context
The IW416HN/A1IMP implements independent ARM-based CPUs: a 160 MHz Wi-Fi CPU handling 802.11a/b/g/n MAC/baseband and a 128 MHz Bluetooth CPU supporting Bluetooth 5.1/5.2 baseband, LE Link Layer, and SCO/eSCO audio processing. Its dual-radio architecture includes dedicated 2.4 GHz and 5 GHz Wi-Fi RF paths with integrated PA/LNA/switches and a shared Bluetooth 2.4 GHz transceiver.
Hardware-level coexistence is enforced via a central packet traffic arbiter managing on-chip Wi-Fi/Bluetooth arbitration and external radio coordination through WCI-2 or PTA interfaces. The SoC supports dynamic rapid channel switching (DRCS) and 20/40 MHz channel bandwidths in both bands, with DFS radar detection compliant to 802.11h in the 5 GHz band.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-band Wi-Fi 4 and Bluetooth combo applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESP32-WROVER-B | Lacks 5 GHz Wi-Fi support; uses internal flash; no hardware PTA coexistence engine | Suitable for cost-sensitive 2.4 GHz-only applications but cannot replace IW416HN/A1IMP in dual-band or coexistence-critical deployments | Select only if 5 GHz operation and deterministic Wi-Fi/Bluetooth arbitration are not required |
| BCM43455C0 | Supports Wi-Fi 5 (802.11ac) and Bluetooth 5.0; requires external PA/LNA; no integrated OTP for MAC storage | Higher throughput but increases BOM complexity and layout effort; lacks industrial temp rating (max +70°C) | Choose when Wi-Fi 5 performance is mandatory and design can accommodate external RF components |
Compared with ESP32-WROVER-B and BCM43455C0, the IW416HN/A1IMP uniquely combines industrial temperature operation, integrated 5 GHz RF front-end, and hardware-enforced coexistence-making it the only option for space-constrained, mission-critical dual-band edge gateways requiring guaranteed real-time radio arbitration.

FAQ
What is the operating temperature range for the IW416HN/A1IMP?
The IW416HN/A1IMP is rated for industrial operation from −40 °C to +85 °C. This specification is validated across all functional blocks-including Wi-Fi RF, Bluetooth baseband, SDIO interface, and power management-and ensures reliable startup and sustained operation in uncontrolled environments such as outdoor smart meters and factory-floor gateways. The IW416HN/A1IMP maintains full compliance with IEEE 802.11n and Bluetooth 5.2 features across this entire range.
Does the IW416HN/A1IMP support 5 GHz Wi-Fi operation?
Yes, the IW416HN/A1IMP fully supports 5 GHz Wi-Fi operation in accordance with IEEE 802.11a/n standards. It covers 23 non-overlapping 20 MHz channels (36–165) and 14 40 MHz channels (36–40 through 157–161), including DFS-compliant radar detection per 802.11h. The integrated 5 GHz PA/LNA/switch enables single-antenna concurrent 5 GHz Wi-Fi and Bluetooth operation, and dual-antenna independent operation-both validated in the IW416 Design Guide (AN13125).
What host interfaces does the IW416HN/A1IMP provide for Wi-Fi and Bluetooth connectivity?
The IW416HN/A1IMP provides SDIO 3.0 (up to 50 MHz) for Wi-Fi host communication and a high-speed UART (up to 3 Mbit/s) for Bluetooth HCI transport. These interfaces are electrically isolated and independently clocked, enabling parallel host-side processing. The SDIO interface supports memory-mapped register access and DMA transfers, while the UART includes RTS/CTS flow control-both confirmed functional in the IW416HN/A1IMP's HVQFN68 package per the official pinout table.
How does the IW416HN/A1IMP handle coexistence between Wi-Fi and Bluetooth radios?
The IW416HN/A1IMP implements hardware-based coexistence using a central packet traffic arbiter that enforces deterministic arbitration between its on-chip Wi-Fi and Bluetooth radios. In single-antenna mode, it supports simultaneous 5 GHz Wi-Fi and Bluetooth operation; in 2.4 GHz, it arbitrates TX/RX access per Table 5 of the datasheet. External radio coexistence is supported via WCI-2 or PTA interfaces-both physically implemented on the IW416HN/A1IMP's HVQFN68 package pins.
Is the IW416HN/A1IMP pin-compatible with other variants in the IW416 family?
Yes, the IW416HN/A1IMP shares identical pinout and footprint with all HVQFN68-packaged IW416 variants (e.g., IW416HN/A1CK, IW416HN/A1IK). Pin assignments-including SDIO, UART, RF control, and coexistence signals-are fixed across industrial and commercial temperature grades in this package. This allows drop-in replacement within the same package family, provided host firmware accounts for temperature-grade-specific calibration data stored in OTP memory.
