IW611UK/A1IZ

RF Transceiver ICS Overview

The IW611UK/A1IZ is a highly integrated 2.4/5 GHz dual-band 1x1 Wi-Fi 6 (802.11ax) and Bluetooth 5.4 single-chip solution by NXP USA Inc. It features an integrated Wi-Fi MAC, baseband, direct-conversion radio with PA, LNA, and Tx/Rx switch, eliminating the need for external RF front-end modules. The device supports SDIO 3.0 for Wi-Fi and UART for Bluetooth host interfaces. Key specifications include a maximum data rate of 480 Mbps, output power of 21 dBm, and sensitivity of -99.5 dBm. It operates within a temperature range of 0 to 70°C or -40 to 85°C depending on the variant.

RF Transceiver ICS Feature Summary

• Integrates full-function Wi-Fi 6 subsystem with direct-conversion radio and built-in power amplifier, low-noise amplifier, and transmit/receive switch to reduce system complexity.
• Includes independent Bluetooth 5.4 subsystem supporting LE Audio, high-speed 2 Mbit/s data rates, and long-range capabilities.
• Features dedicated CPUs and memories for both Wi-Fi and Bluetooth subsystems enabling real-time, independent protocol processing.
• Supports efficient co-existence between internal radios and external radios such as LTE.

RF Transceiver ICS Applications

• Smart home devices and accessories
• Industrial automation gateways
• Smart appliances and energy systems
• IoT sensors and controllers

RF Transceiver ICS Procurement Notes

Verify the specific suffix (e.g., UK/A1IZ) against official NXP documentation to confirm package type, temperature grade, and certification status. Ensure compatibility with host processor interfaces (SDIO/UART). Confirm RoHS3 compliance and lead times with authorized distributors prior to ordering.

RF Transceiver ICS Selection Notes

Select this component for applications requiring compact form factors due to its high integration and minimal external BOM. Consider the IW611 when Wi-Fi 6 throughput and Bluetooth 5.4 features are needed in a single chip. Evaluate thermal requirements based on the specified operating temperature range for the specific suffix variant.

RF Transceiver ICS Part Context

The IW611 belongs to NXP’s wireless solutions portfolio designed for IoT and industrial markets. It complements other NXP chips like the IW612 and RW610, offering a cost-effective alternative for dual-band connectivity without the third radio found in tri-band models. It utilizes NXP’s 802.11ax technology for improved network efficiency.

RF Transceiver ICS Replacement Considerations

The IW612 is a compatible upgrade offering additional 802.15.4 support. For legacy replacements, consider the 88W8987 for Wi-Fi 5 applications. Verify pinout and software compatibility when substituting with other NXP wireless MCUs or transceivers.
