AW-CU570 - Tri-Radio Wi-Fi 6 + BLE 5.3 + 802.15.4 Wireless MCU LGA
MPN： AW-CU570 ✓ 啟用中AW-CU570 概覽
A wireless MCU (also called a Wi-Fi MCU module or tri-radio module) is a System-on-Module that combines an embedded microcontroller with one or more radio transceivers, providing a turnkey wireless connectivity solution for connected products. The product hierarchy places the AW-CU570 as: tri-radio module -> wireless MCU module -> IoT module -> embedded wireless subsystem. This integration eliminates the need to separately source and certify a discrete MCU plus a Wi-Fi/BLE combo chipset, simplifying FCC/ETSI/CE RF compliance and reducing BOM and time-to-market.
Key features include dual-band 2.4/5/6 GHz Wi-Fi 6 (802.11ax) with WPA3 security, Bluetooth LE 5.2 with LE Audio, 802.15.4 for Thread/Zigbee/Matter, an on-board PCB antenna option plus RF pin for external antenna, and Matter-ready application-layer interoperability. The module exposes SDIO/UART/USB/SPI/I2C host interfaces, multiple GPIO, and integrated flash + RAM sufficient for typical IoT firmware stacks. Designed for tight integration and security, the AW-CU570 includes hardware crypto acceleration and secure boot.
Architecturally, the AW-CU570 leverages the NXP RW612 silicon, which uses a Cortex-M33 core for application processing and dedicated radio subsystems. By integrating the matching RF front-end, balun, and crystal into a pre-certified LGA module, AzureWave eliminates the most common sources of Wi-Fi/BLE RF failures (mismatch, harmonics, EMI re-radiation) and allows the host PCB to be designed with minimal RF expertise.
Typical applications include connected smart-home appliances (Matter-over-Wi-Fi lighting, locks, thermostats), enterprise and industrial IoT gateways, smart energy metering, asset tracking and smart accessories, and Matter-over-Thread border routers. The single-rail 3.3 V supply and small footprint also suit battery-powered wearables.
When designing in this module, follow AzureWave's reference design for the host PCB keep-out area around the antenna, honor the module's thermal and supply-rail decoupling guidelines, and ensure the chosen regulatory domain (FCC/IC/CE/TELEC/MIC) is supported on the part variant ordered. The module is pre-certified only as a component - the final product still requires an unintentional-radiator / SAR / host-integrator review.
This page synthesizes distributor pricing, drop-in module alternative sourcing, and practical host-PCB design notes that go beyond the AzureWave datasheet summary, helping hardware engineers evaluate the AW-CU570 against alternative tri-radio modules.

典型應用
AW-CU570 適用於 6 應用s: Matter-over-Wi-Fi Smart Lighting, Smart Home Thermostats and HVAC, Industrial IoT Gateways and Sensors, Smart Energy Meters and Sub-meters, Wearable and Personal Health Devices, Enterprise Asset Tracking.
Matter-over-Wi-Fi Smart Lighting
The AW-CU570's tri-radio architecture (Wi-Fi 6 plus BLE plus 802.15.4) and Matter application-layer support make it a single-PCB solution for connected luminaires that need to join Matter-over-Wi-Fi or Matter-over-Thread networks without a separate hub. The module's 3.3 V single-supply rail simplifies integration into constant-current LED-driver products that already provide 3.3 V to the microcontroller. WPA3 security and hardware crypto acceleration protect OTA firmware updates, while BLE 5.2 enables commissioning via smartphone without a hub. Designers should follow AzureWave's antenna keep-out around the metal heatsink of the luminaire to preserve radiated performance.

Smart Home Thermostats and HVAC
For connected thermostats, the AW-CU570's Matter interoperability allows the same SKU to join Apple Home, Google Home, Amazon Alexa, and SmartThings networks. The BLE 5.2 radio supports proximity-based presence detection (auto-away/auto-home), and the 802.15.4 radio can act as a Thread border router for end-node devices such as temperature sensors. The single 3.3 V rail matches typical thermostat power trees supplied from 24 VAC through a small isolated DC-DC. Designers should validate Thermostat-CE and energy-consumption compliance for the full product, since the module is pre-certified but the host still needs unintentional-radiator testing.
推薦
Industrial IoT Gateways and Sensors
Industrial sensor nodes benefit from the AW-CU570's tri-band Wi-Fi 6 (2.4/5/6 GHz) for high-throughput or long-range uplink to plant gateways, plus BLE 5.2 for local configuration by technicians using a phone, and 802.15.4 for sub-GHz mesh-style sensor networks. The Arm Cortex-M33 in the host SoC handles edge-compute workloads and can run Thread/Bluetooth/Modbus/OPC-UA bridges concurrently. Single 3.3 V supply simplifies powering the module from industrial 24 V via a buck regulator, reducing the host BOM. The high immunity of Wi-Fi 6 to co-channel interference is valuable in dense factory RF environments.
推薦
Smart Energy Meters and Sub-meters
Smart meters require wireless connectivity that survives long product lifecycles and connects to multiple ecosystems. The AW-CU570's Matter-over-Thread support and hardware crypto acceleration allow utilities and OEMs to standardize on a single wireless MCU module across both consumer and enterprise deployments. Tri-band Wi-Fi 6 covers utility-deployed customer-premises Wi-Fi while 802.15.4 supports neighborhood-area metering networks. Regulatory pre-certification reduces the certification burden for metering products where each radio retest can add weeks to the launch schedule.
推薦
Wearable and Personal Health Devices
Wearables benefit from the AW-CU570's small LGA footprint, single 3.3 V supply, and Matter/BLE 5.2/LE Audio support. LE Audio enables broadcast audio plus Auracast hearing-aid companion features, while BLE 5.2 enables high-precision positioning via Bluetooth Channel Sounding for indoor wayfinding. The module's low-power sleep modes help wearables meet multi-day battery targets, and the integrated Cortex-M33 can run on-device health algorithms without an additional application processor. Designers must carefully validate the antenna performance inside a small-form-factor wearable housing.
推薦
Enterprise Asset Tracking
For enterprise and warehouse asset-tracking tags, the AW-CU570's tri-band Wi-Fi 6 capability provides robust connectivity to corporate wireless infrastructure across buildings, BLE 5.2 enables proximity-based location services, and 802.15.4 (Thread) supports mesh tracking networks in warehouses with poor Wi-Fi coverage. The Cortex-M33 application core can run on-tag sensor fusion for movement detection, while the radios handle uplink. The 3.3 V supply matches common battery-backed tags using a coin-cell or rechargeable Li-ion configuration with a load switch.

設計說明
Honor the antenna keep-out area on the host PCB as specified in the AzureWave AW-CU570 Reference Design Guide Rev. 01. The PCB stack-up should keep-out ground planes, copper pours, and component keep-out zones around the antenna region to preserve radiated RF performance and maintain regulatory modular approval. Placing the module at the corner of the host PCB with the antenna facing the edge is the typical layout; do not place the module under a metal battery, shield can, or display.
Provide the AW-CU570 with a clean 3.3 V rail: bulk decoupling (10 uF + 1 uF + 0.1 uF) close to the module's power pins. Although the module accepts 3.3 V directly, Wi-Fi TX bursts draw transient currents that can disturb a noisy rail; use an LDO or quiet buck regulator with adequate transient response. For battery-powered designs, use a load switch to duty-cycle the 3.3 V rail during deep sleep and avoid continuous bias on the regulator.
Do not assume the module's modular approval extends to your end product - you still need unintentional-radiator testing on the host, and you must keep the antenna intact (no metal shielding, no metal-bezel antenna shorts). When changing from a chip-down RW612 design to the AW-CU570 module, your firmware (NXP SDK, MCUXpresso) is unchanged but your pin-out, host-PCB area, and BOM list change. Verify the chosen regulatory domain (FCC/IC/CE/TELEC/MIC) is supported on the exact module variant you order.
