Product details
Overview
IW612HN/A1IMP from NXP Semiconductors is a tri-radio SoC integrating 2.4/5 GHz Wi-Fi 6 (802.11ax), Bluetooth 5.2, and IEEE 802.15.4 radios in a single chip for Matter-enabled IoT edge devices. It delivers 1×1 SU/MU-MIMO Wi-Fi 6 up to 80 MHz bandwidth, +21 dBm 802.15.4 transmit power, and dual-mode I2S/PCM audio interface - enabling concurrent local control and cloud connectivity in smart home hubs, Thread border routers, and voice-controlled appliances.
For engineers reviewing the IW612HN/A1IMP datasheet, IW612HN/A1IMP pinout, IW612HN/A1IMP application, or IW612HN/A1IMP equivalent, key selection criteria include its integrated SDIO 3.0 (208 MHz), UART HCI (3 Mbps), SPI (10 MHz) host interfaces; coexistence-optimized dual-antenna RF architecture; and hardware-accelerated support for WPA3, LE Audio isochronous channels, and Thread 1.3.0 over 802.15.4.
Technical Context
The IW612HN/A1IMP implements three independent protocol stacks with dedicated CPUs and memory: a full Wi-Fi 6 MAC/baseband/radio subsystem supporting OFDMA, MU-MIMO, and 802.11az ranging; a Bluetooth 5.2 stack with dual SCO/eSCO links, WBS, and LE 5.3 features including long range and 2 Mbps; and an 802.15.4 MAC accelerator with AES-128, RSSI, and packet timestamping.
Its RF architecture integrates PA/LNA/switches for both 2.4 GHz and 5 GHz Wi-Fi bands, shares antenna paths between Bluetooth and 802.15.4 in single-antenna mode, and supports diplexer-based dual-antenna isolation. Coexistence is managed via hardware-assisted signaling across SDIO, UART, and SPI interfaces without external arbitration logic.
