PAU1800 is a family of patented GreenRadioTM monolithic Bluetooth audio System-on-Chips (SoCs) mainly for wireless
audio/voice applications. It comprises 2 CPU and 2 DSP processors, a Bluetooth 5.2 EDR/LE dual mode radio, a stereo
audio codec, a battery charger, memory, and host interface peripherals. PAU1800 series features low power digital active
noise cancellation (ANC) technology integrated in the SoC.
