Product details
Overview
IW612HN/A1CMP 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. It delivers 1×1 dual-band Wi-Fi 6 with MU-MIMO/OFDMA, Bluetooth LE 5.3 with 2 Mbps data rate and long range, and Thread-capable 802.15.4 supporting Matter over Thread. The device serves as both Matter Controller and Thread Border Router in smart home gateways and industrial edge nodes.
For engineers reviewing the IW612HN/A1CMP datasheet, IW612HN/A1CMP pinout, IW612HN/A1CMP application, or IW612HN/A1CMP equivalent, key selection criteria include integrated coexistence management across three radios, SDIO 3.0 (up to SDR104) for Wi-Fi, UART (3 Mbps) for Bluetooth, and SPI (10 MHz) for 802.15.4 - all with dedicated protocol processors and hardware-accelerated audio interfaces (I2S/PCM).
Technical Context
The IW612HN/A1CMP implements independent protocol stacks with dedicated CPUs and memories for Wi-Fi, Bluetooth/LE, and 802.15.4 subsystems - enabling real-time, non-interfering concurrent operation. Its RF architecture integrates PA/LNA/switches for both 2.4 GHz and 5 GHz bands, eliminating external FEMs while supporting DFS radar detection and 802.11az ranging.
Bluetooth 5.2 support includes SCO/eSCO with hardware-accelerated PPEC for speech quality, A2DP, WBS (dual-link), and LE Audio via isochronous channels. The 802.15.4 radio provides +21 dBm transmit power, 128-bit AES encryption, MAC acceleration, and precise packet timestamping - all compliant with IEEE 802.15.4-2020 and Thread 1.3.

FAQ
What wireless standards does the IW612HN/A1CMP support?
The IW612HN/A1CMP supports IEEE 802.11ax (Wi-Fi 6) for 2.4 GHz and 5 GHz bands, Bluetooth 5.2 with LE 5.3 enhancements, and IEEE 802.15.4-2020 for Thread 1.3.1 mesh networking. All three radios operate concurrently with hardware-enforced coexistence, and the IW612HN/A1CMP is certified for Matter over Wi-Fi and Thread. It does not support Wi-Fi 7, Bluetooth 5.4, or sub-GHz 802.15.4 variants.
Does the IW612HN/A1CMP require external RF front-end modules?
No, the IW612HN/A1CMP integrates PA, LNA, and transmit/receive switches for both 2.4 GHz and 5 GHz bands, eliminating the need for external RF front-end modules (FEMs). This integration reduces BOM cost and PCB area while maintaining compliance with FCC/CE radiated emission limits. External diplexer or antenna switch may still be required depending on single- vs. dual-antenna configuration per IW612_PB Figure 1 and Figure 2.
How does the IW612HN/A1CMP handle Matter certification requirements?
The IW612HN/A1CMP natively supports Matter 1.3 through its integrated Thread Border Router and Matter Controller capabilities, using certified Thread 1.3.1 and Wi-Fi 6 stacks. It implements required security primitives including P256 ECC, SHA-256, and AES-128, and supports DCL (Device Commissioning Library) and CHIP tool integration. The IW612HN/A1CMP passes all mandatory Matter test suites for Wi-Fi/Thread bridging, local control, and cloud provisioning without host-side software augmentation.
What audio interfaces are available on the IW612HN/A1CMP?
The IW612HN/A1CMP provides shared I2S/PCM digital audio interfaces supporting both mono and dual-channel modes. It accepts 4.096 MHz or 2.048 MHz master clocks and operates at sampling rates from 8 kHz to 16 kHz. Hardware-accelerated SCO/eSCO processing with PPEC enables wideband speech (WBS) quality, and the interface is directly compatible with common ADC/DAC ICs used in smart speakers and voice remotes.
What host processor interfaces does the IW612HN/A1CMP provide?
The IW612HN/A1CMP offers three dedicated host interfaces: SDIO 3.0 (supporting SDR104 up to 208 MHz) for Wi-Fi, UART (3 Mbps) for Bluetooth HCI, and SPI (10 MHz) for 802.15.4 MAC access. Each interface uses independent hardware blocks with DMA support, ensuring zero bus contention and deterministic latency - critical for real-time Matter and voice assistant applications.
