NXP has recently launched the IW623, a Tri-band Wi-Fi 6E and Bluetooth LE Audio SoC, which can be considered as the 4th member of the IW62x family, as back in 2020, NXP launched the IW620, with Wi-Fi 6 and Bluetooth 5.1 connectivity. After that, in January 2022, they released the IW612 tri-radio SoC, adding 802.15.4 support for Matter-enabled smart home gateways, and later in September 2025, they launched the IW693 Wi-Fi 6E SoC with concurrent dual-Wi-Fi and Bluetooth for industrial IoT and automotive markets.
The IW623 Wi-Fi 6E Bluetooth SoC also includes features like 2×2 MU-MIMO, OFDMA, Target Wake Time (TWT), wireless multi-streaming, adaptive scheduling, and agile channel switching for congested environments. A dedicated Wi-Fi/Bluetooth coexistence engine with hardware and software arbitration ensures smooth operation when both radios are active, while the integrated PA/LNA/Switch reduces external RF components and improves range. Host connectivity is available over PCIe and SDIO for Wi-Fi, and UART for Bluetooth. It also supports isochronous channel support for multi-stream and LE Audio broadcast. These features make this SoC suitable for smart home hubs, IoT gateways, wireless cameras, industrial devices, and medical equipment.
NXP IW623 specifications:

The block diagram and application diagram are very similar to the IW693, which we have written in the past. One major difference is that the IW623 replaces the SPDT RF switch with a simpler diplexer-based design with lower loss and more efficient RF routing.
The IW623 supports full Wi-Fi 6/6E software stacks with STA and mobile AP modes, OFDMA, Target Wake Time (TWT), agile channel switching, and TSF host clock synchronization, while Bluetooth software includes both Classic and Low Energy with LE Audio, advertising extensions, long range, and high speed. NXP also integrates coexistence management with real-time algorithms for simultaneous Wi-Fi and Bluetooth operation.
NXP mentions that the certified IW623-based modules will be available from the company’s module partners starting in Q1 2026. More information is available on the product page and press release page.
