The BES2720ZP is an ultra-low power, high performance, Bluetooth audio SoC. The platform incorporates a powerful CPU subsystem comprising an Arm Cortex-M55 processor, a Tensilica HiFi 4 DSP (optional) and an Ethos-U55 NPU (optional). In addition, it incorporates a host subsystem comprising a dual-core STAR-MC1 processor with a dual-core BES proprietary coprocessor (BECO) for advance signal processing and NN workloads. This combination significantly reduces power consumption while providing substantial application processing capabilities.

The platform incorporates a dual-mode Bluetooth 6.1 subsystem for both Bluetooth classic and LE audio. 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.
