原相PAU1803原理图与规格书分享
PAU1800 is a family of patented GreenRadioTM monolithic Bluetooth audio System-on-Chips (SoCs) mainly for wirelessaudio/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.
Full compliance with Bluetooth v5.2 EDR/BLE dual
mode specification
Embedded 32-bit CPU as System Processor (SP)
Embedded RISC-V CPU with floating point and
DSP/SIMD extension as Application Processor (AP)
Two 24-bit Audio DSP coprocessors
Internal System in Package (SiP) flash memory
Stereo audio DAC/ADC and headphone drivers
Up to 3 microphone inputs (2 analog and 1 digital
MEMS)
