Product details
Overview
IW612HN/A1CK from NXP Semiconductors is a single-chip tri-radio IC integrating 2.4/5 GHz Wi-Fi 6 (802.11ax), Bluetooth 5.2, and IEEE 802.15.4 radios for Matter-enabled IoT edge devices. It delivers 1×1 dual-band Wi-Fi 6 with integrated PA/LNA, Bluetooth LE 5.3 with 2 Mbps data rate and isochronous channels, and Thread-capable 802.15.4 supporting +21 dBm transmit power - all in one die for smart home hubs, gateways, and industrial controllers.
For engineers reviewing the IW612HN/A1CK datasheet, IW612HN/A1CK pinout, IW612HN/A1CK application, or IW612HN/A1CK equivalent, key selection criteria include its SDIO 3.0 (up to 208 MHz) Wi-Fi host interface, UART HCI (3 Mbps) for Bluetooth, SPI (10 MHz) for 802.15.4, dual-antenna coexistence architecture, and dedicated CPUs enabling independent real-time protocol processing without host dependency.
Technical Context
The IW612HN/A1CK implements three physically separate radio subsystems sharing a common substrate but operating with independent baseband processors and memory: Wi-Fi 6 MAC/baseband/radio supports 20/40/80 MHz bandwidths and HE SU/MU-MIMO; Bluetooth 5.2 subsystem includes full BDR/EDR and LE 5.3 stacks with hardware-accelerated SCO/eSCO and WBS; 802.15.4 subsystem complies with IEEE 802.15.4-2020 and integrates MAC acceleration, AES-128 encryption, and timestamped packet handling.
Coexistence is managed via hardware-assisted protocols and configurable antenna routing - single-antenna mode uses diplexer-based Tx/Rx path separation across bands, while dual-antenna mode assigns dedicated antennas per radio domain (Wi-Fi 2.4 GHz, Wi-Fi 5 GHz, Bluetooth/802.15.4). All subsystems support concurrent operation with deterministic latency guarantees through dedicated interrupt and DMA pathways.

FAQ
What is the primary function of the IW612HN/A1CK in a Matter ecosystem?
The IW612HN/A1CK serves as a certified Matter Controller and Thread Border Router, enabling local control and provisioning of Matter devices over Wi-Fi and Thread networks. It executes the full Matter stack - including DCL, CSA-compliant security, and cluster server logic - while concurrently managing Bluetooth LE for mobile app interaction and voice assistant integration. Its integrated tri-radio architecture ensures deterministic timing for Matter attribute reporting and OTA updates without host processor dependency.
Does the IW612HN/A1CK support Wi-Fi 6 features like OFDMA and MU-MIMO?
Yes, the IW612HN/A1CK fully implements IEEE 802.11ax (Wi-Fi 6) with 1×1 SU-MIMO and MU-MIMO support, OFDMA downlink/uplink scheduling, Target Wait Time, HE Dual-NAV, and UL Carrier Sensing.

The IW612HN/A1CK integrates a shared I2S/PCM interface supporting mono and dual-channel modes at 8–16 kHz sampling rates. It enables simultaneous Bluetooth HFP (hands-free profile) and A2DP (advanced audio distribution) streams using hardware-accelerated SCO/eSCO processing and PPEC speech enhancement. The interface operates in central or peripheral mode and shares pins between I2S and PCM functions to reduce pin count while maintaining full audio fidelity for voice assistant front-ends.
