IW611UK-A1ITZ 概要
A Wi-Fi/Bluetooth combo RF transceiver IC combines a full 802.11ax baseband, MAC, RF front end, and a Bluetooth 5.4 controller on a single die. Within the wireless connectivity hierarchy (RF transceiver -> combo connectivity IC -> wireless system-on-chip), such devices replace discrete Wi-Fi and BT chipsets, cutting bill-of-materials cost, board area, and coexistence complexity in connected products.
Key features include dual-band 2.4 GHz and 5 GHz operation with 1x1 Wi-Fi 6 throughput and OFDMA efficiency, Bluetooth 5.4 and BLE support for long-range and low-power links, and a very high degree of on-chip integration that NXP states contributes to very low system cost. Single-chip integration of both radios simplifies antenna coexistence design and reduces external component count.
The IW611 architecture targets high-volume smart-device designs where integration, power efficiency, and certification-ready radio performance matter more than multi-stream MIMO throughput. The 140-XFBGA WLCSP package keeps the footprint compact enough for accessories, appliances, and embedded gateways.
Typical applications include smart home devices and accessories, smart appliances, smart energy metering, industrial automation nodes, and IoT gateways needing concurrent Wi-Fi and Bluetooth connectivity.
Design consideration: because both radios share one chip, follow the NXP datasheet guidance on shared-antenna or dual-antenna layouts, power-supply decoupling, and RF trace impedance to guarantee coexistence performance.
This page synthesizes distributor pricing, drop-in alternative data, FAQs, and practical design notes not found in the manufacturer datasheet, so engineers can evaluate the IW611UK-A1ITZ in one place.

主な用途
IW611UK-A1ITZ の用途: 6 件s: Smart Home Devices and Accessories, Smart Appliances, Smart Energy Metering, Industrial Automation Nodes, IoT Gateways, Smart Devices and Wearable Accessories.
Smart Home Devices and Accessories
The IW611UK-A1ITZ fits smart home products because it combines 2.4/5 GHz Wi-Fi 6 and Bluetooth 5.4 in one chip, eliminating a second radio and its coexistence circuitry. Wi-Fi 6 OFDMA improves performance in dense home networks with dozens of connected devices, while BLE 5.4 handles low-power commissioning, app pairing, and beacon-based presence. NXP states the high integration contributes to very low system cost - critical at consumer price points. Placed on a compact 140-XFBGA WLCSP footprint, the IC suits plugs, bulbs, sensors, and accessories where board area and antenna placement are constrained; dual-band support lets products use the cleaner 5 GHz band for latency-sensitive voice and video accessories.
おすすめ
Smart Appliances
Washing machines, refrigerators, ovens, and HVAC equipment need reliable cloud connectivity plus a local commissioning path, which the IW611UK-A1ITZ provides in a single 140-ball WLCSP device. The 5 GHz band avoids the congested 2.4 GHz spectrum typical of appliance bays and dense residential environments, while Bluetooth 5.4 supports first-time setup from a phone without Wi-Fi credentials being entered on the appliance. NXP explicitly lists smart appliances among target applications for the IW611. Because the radios are integrated, appliance makers reduce component count, qualification effort, and antenna coexistence layout work, lowering total system cost; Wi-Fi 6 features such as target wake time also help appliances meet standby power regulations.
おすすめ
Smart Energy Metering
Smart energy infrastructure - electricity, gas, and water meters plus home energy gateways - benefits from the IW611UK-A1ITZ's combination of dual-band Wi-Fi 6 backhaul and BLE 5.4 local access. NXP names smart energy among the IW611's primary target markets. The 1x1 Wi-Fi 6 radio delivers sufficient throughput for meter data reporting while target wake time and power-efficient BLE keep average consumption low in battery-assisted metering nodes. Single-chip integration reduces the meter PCB's RF section to one device, which matters for high-volume metering deployments where even fractions of a dollar per unit compound across millions of installed meters. Bluetooth enables in-home display pairing and local reading via smartphone apps.
おすすめ
Industrial Automation Nodes
In factory automation, the IW611UK-A1ITZ connects sensors, actuators, and HMI panels to plant Wi-Fi 6 networks while offering BLE for maintenance and diagnostics via handheld tools. Wi-Fi 6's OFDMA and improved scheduling deliver more deterministic latency than 802.11n in radio-dense factory floors where dozens of nodes share spectrum. NXP explicitly targets industrial automation for the IW611. The dual-band capability lets integrators place control traffic on the quieter 5 GHz band, and the single-chip design simplifies EMC qualification of industrial control boards. The compact 140-XFBGA package also fits retrofit nodes where existing sensor housings leave little room for additional radio hardware.
おすすめ
IoT Gateways
Entry-level IoT gateways use the IW611UK-A1ITZ as the Wi-Fi access point and BLE provisioning radio for downstream devices. The 2.4/5 GHz dual-band 1x1 Wi-Fi 6 interface provides 802.11ax hotspot capability for sensors and accessories, while Bluetooth 5.4 handles onboarding of BLE-only devices such as tags and sensors. NXP lists gateways among the IW611's target applications. High integration reduces gateway BOM cost and board area, which is significant in consumer-priced gateway hardware. Wi-Fi 6 air-interface efficiency helps a gateway serve many concurrent low-rate IoT clients without the airtime collapse typical of older 802.11n chipsets, and the shared-chip architecture simplifies simultaneous Wi-Fi/BLE coexistence design.
おすすめ
Smart Devices and Wearable Accessories
Connected accessories such as speakers, cameras, hubs, and display pucks need both a broadband Wi-Fi link and a low-power BLE channel for app control; the IW611UK-A1ITZ supplies both from a single 140-ball WLCSP die. NXP positions the IW611 for smart devices and accessories as a primary market. The chip-scale package's small footprint enables compact antenna-in-board designs in enclosures where mechanical volume is fixed, and eliminating a separate BT controller removes an entire qualification cycle from the accessory's schedule. Wi-Fi 6 target wake time helps battery-backup accessories achieve long standby life, while BLE 5.4 supports secure re-keying and finding features in modern smart accessory ecosystems.

- Single-chip dual-radio integration （vs Discrete Wi-Fi + BT two-chip solutions)
設計ノート
The 140-ball XFBGA WLCSP package demands tight RF layout discipline: keep the 50-ohm antenna feedline as short as possible, reference it to an unbroken ground plane, and follow the NXP IW611 datasheet reference layout for ball-side decoupling. Because both Wi-Fi and BLE radios share the die, antenna coexistence strategy (shared PIFA with switch vs dual antenna) must be decided before routing - changing later forces a board respin. Follow NXP's hardware design application guidance for the IW611 rather than copying layouts from two-chip Wi-Fi/BT designs.
Wi-Fi 6 transmit bursts create fast, high-amplitude current transients on the supply rail. Decouple each power ball per the NXP IW611 datasheet recommendations, with bulk capacitance near the module and 100 nF ceramics at the balls. Estimate: budget the DC-DC converter for peak TX current rather than average, since OFDMA burst traffic can present pulsed loads; insufficient supply stiffness shows up first as degraded EVM and reduced throughput on the 5 GHz band rather than as a hard failure.
Do not interchange ordering suffixes without verification: IW611UK-A1ITZ and IW611UK-A1IZ are listed as separate DigiKey catalog items even though they share the same die and datasheet. Confirm the suffix's packing/quality-flow meaning on the NXP product page and standardize on one suffix across your BOM, PLM system, and reflow profile to avoid incoming-inspection mismatches. Also confirm your regulatory certifications (FCC/CE modular approval status) apply to the specific suffix ordered.
