Product details
Overview
IW416HN/A1IK from NXP Semiconductors is an industrial-grade 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 PHY rate and Bluetooth LE 2 Mbps, Long Range, and Periodic Advertising Sync Transfer. It integrates TX PAs, RX LNAs, and RF switches for single- or dual-antenna configurations and targets smart home gateways, industrial automation, and asset tracking systems.
For engineers reviewing the IW416HN/A1IK datasheet, IW416HN/A1IK pinout, IW416HN/A1IK application, or IW416HN/A1IK equivalent, this page delivers verified technical context on coexistence arbitration, SDIO 3.0 + UART host interfaces, HVQFN68 package mapping, industrial temperature support (−40 to 85°C), and hardware-accelerated audio processing via I2S/PCM.
Technical Context
The IW416HN/A1IK implements independent ARM-based CPUs: a 160 MHz Wi-Fi CPU handling IEEE 802.11a/b/g/n MAC/baseband with DFS radar detection and 20/40 MHz channel support, and a 128 MHz Bluetooth CPU executing Bluetooth 5.1/5.2 baseband including LE 2 Mbps, Long Range, and Secure Connections. Both subsystems share dedicated coexistence logic.
Hardware-level packet traffic arbitration enables deterministic Wi-Fi/Bluetooth time-slicing in single-antenna mode and true concurrency in dual-antenna mode. External radio coexistence is supported via WCI-2 (two-wire) and PTA (five-signal) interfaces, with WCI-2 and PCM sharing multi-function pins - requiring interface selection at design time.

FAQ
What is the operating temperature range for the IW416HN/A1IK?
The IW416HN/A1IK is rated for industrial operation from −40 °C to +85 °C. This specification is validated across all functional blocks - Wi-Fi RF, Bluetooth baseband, SDIO/UART interfaces, and internal power regulators - ensuring reliable performance in uncontrolled environments such as factory floors or outdoor deployments. The IW416HN/A1IK maintains full data rate and coexistence functionality across this entire range.
Does the IW416HN/A1IK support 5 GHz Wi-Fi and Bluetooth simultaneously on a single antenna?
Yes, the IW416HN/A1IK supports simultaneous 5 GHz Wi-Fi and Bluetooth operation in single-antenna configuration. This is enabled by hardware-level packet arbitration and RF front-end timing isolation. In contrast, 2.4 GHz Wi-Fi and Bluetooth share the same band and require transmit/receive arbitration - documented in Table 5 of the datasheet. The IW416HN/A1IK implements this arbitration without host CPU involvement.
Which host interfaces does the IW416HN/A1IK provide for Wi-Fi and Bluetooth subsystems?
The IW416HN/A1IK uses SDIO 3.0 for the Wi-Fi subsystem and a high-speed UART (up to 3 Mbit/s) for the Bluetooth subsystem. These are physically separate interfaces with independent drivers and interrupt lines. The IW416HN/A1IK does not support USB or PCIe host connections, and the UART interface includes full RTS/CTS flow control for deterministic BLE data transfer.
How does the IW416HN/A1IK handle coexistence between Wi-Fi and Bluetooth radios?
The IW416HN/A1IK implements a central hardware packet traffic arbiter that schedules Wi-Fi and Bluetooth TX/RX operations at the packet level - eliminating software polling or timer-based arbitration. It supports both single- and dual-antenna configurations, and extends arbitration to external radios via WCI-2 or PTA interfaces. The IW416HN/A1IK's coexistence logic is fully autonomous and requires no host driver intervention.
What audio interfaces are supported by the IW416HN/A1IK?
The IW416HN/A1IK supports both I2S and PCM audio interfaces, implemented on shared multi-function pins. It handles wide-band speech (WBS), SCO/eSCO links, and hardware-accelerated PPEC for speech quality improvement. The IW416HN/A1IK supports 8-bit and 16-bit PCM with up to four time slots, and operates in both central and peripheral modes - making it suitable for voice assistant endpoints and hands-free headsets.
