Product details
Overview
IW416HN/A1CK 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 hardware coexistence arbitration. It delivers full Wi-Fi subsystem functionality plus Bluetooth LE 2 Mbps, Long Range, and Periodic Advertising Sync Transfer for voice-assisted smart home devices.
For engineers reviewing the IW416HN/A1CK datasheet, IW416HN/A1CK pinout, IW416HN/A1CK application, or IW416HN/A1CK equivalent, this page provides verified technical context on SDIO 3.0 + UART host interfaces, HVQFN68 package mapping, commercial temperature range (0–70°C), dual-antenna concurrent operation, and coexistence with external 802.15.4 radios via WCI-2/PTA.
Technical Context
The IW416HN/A1CK integrates independent ARM-based CPUs (Wi-Fi at 160 MHz, Bluetooth at 128 MHz), dedicated baseband/MAC blocks for 802.11n and Bluetooth 5.1/5.2, and on-die RF front ends with integrated 2.4 GHz/5 GHz PAs/LNAs/SPDT switches. Its central hardware packet traffic arbiter manages time-sliced or simultaneous TX/RX between Wi-Fi and Bluetooth radios - including arbitration for external radios via WCI-2 or PTA interfaces.
It supports SDIO 3.0 for Wi-Fi host communication and high-speed UART (up to 3 Mbit/s) for Bluetooth, with shared I2S/PCM audio interfaces and GPIO-muxed peripheral signals. Power management includes deep-sleep, standby, and sleep modes, while security implements AES/CCMP (WPA3/WPA2) and AES/CMAC (802.11w).

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-WROOM-32 | Wi-Fi 4 + Bluetooth 4.2 (not 5.2); no LE 2 Mbps or Long Range; lacks hardware PTA arbiter; uses internal flash instead of OTP for MAC | Targeted at cost-sensitive IoT with basic BLE peripheral roles; unsuitable for PAST, scatternet, or DFS-compliant medical use | Select IW416HN/A1CK when Bluetooth 5.2 features, hardware coexistence, or 5 GHz DFS operation are required. |
| BCM43455C0 | Wi-Fi 5 (802.11ac) + Bluetooth 5.0; supports 2×2 MIMO; larger footprint (WLBGA155); higher power consumption; no integrated 5 GHz PA | Designed for premium smartphones/tablets requiring higher throughput; over-specified for smart home gateways or battery-powered edge nodes | Select IW416HN/A1CK for compact, low-power dual-band solutions where 150 Mbit/s and Bluetooth 5.2 LE features meet requirements. |
Compared with ESP32-WROOM-32 and BCM43455C0, the IW416HN/A1CK delivers Bluetooth 5.2-specific capabilities (PAST, LE 2 Mbps) and hardware-level Wi-Fi/Bluetooth coexistence in a smaller HVQFN68 package - making it optimal for space-constrained, certification-sensitive smart home and healthcare edge devices.

FAQ
What is the operating temperature range for IW416HN/A1CK?
The IW416HN/A1CK is rated for commercial temperature operation from 0 °C to +70 °C. This range is validated per NXP's characterization and supports deployment in indoor consumer electronics such as smart speakers, IP cameras, and retail terminals. Industrial-grade variants (e.g., IW416HN/A1IK) extend to −40 °C to +85 °C but are not applicable to the IW416HN/A1CK part number.
Does IW416HN/A1CK support Wi-Fi 6 or Bluetooth 5.3?
No. The IW416HN/A1CK implements Wi-Fi 4 (802.11n) and Bluetooth 5.2. It does not support Wi-Fi 6 (802.11ax) features such as OFDMA or TWT, nor Bluetooth 5.3 enhancements like LE Audio or Connection Subrating. Its IEEE 802.11n compliance includes MCS0–MCS7 and 40 MHz channel bonding; Bluetooth 5.2 certification covers LE 2 Mbps, Long Range, and PAST.
Can IW416HN/A1CK operate with a single antenna for both Wi-Fi and Bluetooth?
Yes. In single-antenna configuration, IW416HN/A1CK supports simultaneous 5 GHz Wi-Fi and Bluetooth operation. For 2.4 GHz Wi-Fi, transmit and receive operations with Bluetooth are arbitrated in time - meaning they cannot occur simultaneously on the same band but are managed seamlessly by the on-chip hardware PTA arbiter without host intervention.
What host interfaces does IW416HN/A1CK provide for Wi-Fi and Bluetooth connectivity?
The IW416HN/A1CK uses SDIO 3.0 for Wi-Fi host communication and a high-speed UART (up to 3 Mbit/s) for Bluetooth. These are physically separate interfaces with independent voltage domains (VIO_SD for SDIO, AVDD18 for UART). Both support standard protocol stacks - SDIO for Wi-Fi drivers and UART HCI for Bluetooth host controllers - and are fully documented in the IW416 Design Guide (AN13125).
Is external memory required for IW416HN/A1CK operation?
No. IW416HN/A1CK contains sufficient on-chip memory for autonomous operation: boot ROM, internal SRAM for runtime execution, and OTP memory storing MAC address and RF calibration data. External Flash or PSRAM is optional and only needed for custom application firmware storage beyond the SoC's built-in capabilities - not for baseline Wi-Fi/Bluetooth functionality.
