Product details
Overview
IW416HN/A1CMP 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 operation with peak PHY rate of 150 Mbit/s, integrated TX PAs/RX LNAs, and SDIO 3.0 + UART host interfaces. It enables low-cost voice-assist devices, IP cameras, and smart home gateways requiring coexistence-aware wireless connectivity.
For engineers reviewing the IW416HN/A1CMP datasheet, IW416HN/A1CMP pinout, IW416HN/A1CMP application, or IW416HN/A1CMP equivalent, key selection considerations include HVQFN68 package compatibility, commercial temperature range (0–70°C), dual-antenna simultaneous Wi-Fi/Bluetooth operation, and WCI-2/PTA coexistence interface support for multi-radio systems.
Technical Context
The IW416HN/A1CMP integrates independent ARM-based Wi-Fi CPU (160 MHz) and Bluetooth CPU (128 MHz), each with dedicated memory subsystems (SRAM, OTP, boot ROM). Its dual-band radio architecture supports 20/40 MHz channels in both 2.4 GHz (channels 1–13) and 5 GHz (channels 36–165) bands with DFS radar detection and DRCS for rapid band switching.
Hardware-level coexistence is implemented via a central packet traffic arbiter managing on-chip Wi-Fi/Bluetooth arbitration and external radio coordination through WCI-2 (2-wire) or PTA (5-signal) interfaces. The SoC supports shared RF front-end control via RF_CNTL[0–3] signals and uses arbitrated TX/RX scheduling in single-antenna mode per Table 5.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-band Wi-Fi 4 and Bluetooth combo SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESP32-WROVER-B | Single-band 2.4 GHz Wi-Fi 4 only; no 5 GHz support; lacks hardware PTA coexistence logic | Suitable for cost-sensitive 2.4 GHz-only applications; not viable for 5 GHz throughput or multi-radio arbitration | Select IW416HN/A1CMP when 5 GHz band support, DFS compliance, or external radio coexistence are required. |
| RTL8723DS | Supports Wi-Fi 4 + BT 4.2 (not BT 5.2); no LE Long Range or PAST; lower peak PHY rate (72 Mbit/s @ 20 MHz) | Limited to legacy Bluetooth peripherals; insufficient for modern LE audio or extended-range asset tracking | Choose IW416HN/A1CMP for Bluetooth 5.2 features including 2 Mbps LE, secure connections, and periodic sync transfer. |
Compared with ESP32-WROVER-B and RTL8723DS, the IW416HN/A1CMP provides verified 5 GHz operation, hardware-enforced coexistence for multi-radio systems, and full Bluetooth 5.2 feature set - making it the only option among the three qualified for simultaneous dual-band Wi-Fi and advanced LE use cases.

FAQ
What is the operating temperature range for IW416HN/A1CMP?
The IW416HN/A1CMP is rated for commercial temperature operation from 0 °C to +70 °C, as confirmed in Table 2 of the official datasheet. This range is validated for indoor consumer electronics such as smart speakers and home automation hubs. Industrial-grade variants (e.g., IW416HN/A1IMP) support −40 °C to +85 °C but are distinct orderable parts.
Does IW416HN/A1CMP support 5 GHz Wi-Fi and Bluetooth simultaneously on a single antenna?
Yes - the IW416HN/A1CMP supports simultaneous 5 GHz Wi-Fi and Bluetooth operation in single-antenna configuration, as explicitly stated in Section 5.1.2 and Table 5 (Row #1 and #5). In contrast, 2.4 GHz Wi-Fi and Bluetooth share the same antenna with time-arbitrated TX/RX scheduling to avoid collision.
Which host interfaces does IW416HN/A1CMP provide for Wi-Fi and Bluetooth connectivity?
The IW416HN/A1CMP uses SDIO 3.0 for Wi-Fi host communication and a high-speed UART (up to 3 Mbit/s) for Bluetooth HCI transport. Both interfaces are electrically isolated and independently configurable - enabling parallel host-side driver stacks without resource contention.
What coexistence mechanisms does IW416HN/A1CMP implement for multi-radio systems?
The IW416HN/A1CMP implements two coexistence mechanisms: (1) on-chip hardware Packet Traffic Arbiter (PTA) for Wi-Fi/Bluetooth arbitration, and (2) external interfaces - WCI-2 (2-wire) and PTA (5-signal) - for coordinating with third-party radios like 802.15.4. These are documented in Sections 5.2 and 5.3 of the datasheet.
Is IW416HN/A1CMP pin-compatible with other members of the IW416 family?
No - the IW416HN/A1CMP uses the HVQFN68 package, while the WLCSP76 variant (e.g., IW416UK/A1CZ) has completely different bump mapping and footprint. Even within HVQFN68, pin functions are fixed per Table 6; no alternate pinout configurations or software-selectable muxing is supported for core interfaces like SDIO or UART.
