The AW611 from NXP Semiconductor is a 2.4/5 GHz Wi-Fi 6 (802.11ax) and Bluetooth (LE) 5.2 Module. It is optimized for the automotive market with AEC-Q100 Grade 3 qualification. This module has a Wi-Fi subsystem that integrates a Wi-Fi MAC, baseband, and direct-conversion radio with PA, LNA and transmit/receive switch and removes the need for an RF front-end module (FEM). This module also integrates an independent Bluetooth 5.2 subsystem that supports Bluetooth Profiles such as hands-free (HFP), advanced audio distribution profile (A2DP) for audio streaming as well as additional profiles like dual wideband speech (WBS). This high degree of integration leads to low system costs and a minimum external BOM while achieving efficient coexistence between all internal radios as well as external radios, such as LTE.
For Wi-Fi 6 applications, it supports 80 MHz channels with uplink/downlink MU-MIMO and OFDMA. For Bluetooth 5.2 applications, it supports long-range and extended advertising for Bluetooth LE along with AoA/AoD Direction Finding. This module also supports LE Audio using Isochronous channels for a better overall audio experience. It has dedicated, independent CPUs and memories for Wi-Fi and Bluetooth and an efficient power management system supporting low-power modes. It can be controlled via an SDIO 3.0 host (Wi-Fi) and UART host (Bluetooth) interfaces. The AW611 is ideal for automotive applications like communication for EV charging, hands-free voice, infotainment, navigation, remote diagnostics & software updates, telematics and user interface mirroring.
