The BES2720W is an ultra-low power, high performance audio SoC with integrated Bluetooth and Wi-Fi. The platform incorporates a powerful CPU subsystem comprising a dual-core Arm Cortex-M55 processor with a dual-core BES proprietary coprocessor (BECO NPU) for advance signal processing and NN workloads, and an Ethos-U55 NPU (optional). This combination significantly reduces power consumption while providing substantial application processing capabilities, ideally for spatial audio processing.

The platform incorporates a dual-mode Bluetooth 6.1 subsystem for both Bluetooth classic and LE audio, a low power Wi-Fi subsystem for energy-efficient wireless connectivity, as well as an audio codec. The highly integrated solution is optimized through the use of IBRT technology, a BES patented sniffing technique that incorporates Forward Error Correction (FEC) for enhanced RF performance in TWS systems.
