PAU1800 is a family of patented GreenRadioTM monolithic Bluetooth audio System-on-Chips (SoCs) mainly for wireless
' t- d# b5 p: Y- `; R2 v# |" I' Waudio/voice applications. It comprises 2 CPU and 2 DSP processors, a Bluetooth 5.2 EDR/LE dual mode radio, a stereo
# R4 d% v6 Q, C$ X' h5 l$ Yaudio codec, a battery charger, memory, and host interface peripherals. PAU1800 series features low power digital active
noise cancellation (ANC) technology integrated in the SoC.
