The BES3303-P1S is a single-chip audio codec designed for USB Type-C headphones / headsets. The signal path, from the analog input through the hardware DSP core to the analog output, is optimized for low latency and low noise performance.

The platform incorporates an audio codec and a cap-less headphone driver, as well as a high performance dual-core STAR-MC1 processor with a dual-core BECO NPU, a BES proprietary coprocessor for advance signal processing and NN workloads, extensive software features and product customization. The BES3303-P1S is designed to minimize external components and reduce BOM costs. It is manufactured by using an advanced low-power CMOS process and assembled within a FCCSP package.
