高通QCC3020芯片datasheet.pdf

QCC3020 VFBGA is a system on-chip (SoC) with on-chip Bluetooth, audio and programmable application processor. It includes high-performance, analog, and digital audio codecs, Class-D earphone speaker driver, advanced power management, Li-ion battery charger, light-emitting diode (LED) drivers, and flexible interfaces including interintegrated circuit sound (I²S) input, inter-integrated circuit interface (I²C), universal asynchronous receiver transmitter (UART), and programmable input/output (PIO). An application-dedicated Developer Processor and a system Firmware Processor run code from an external quad serial peripheral interface (QSPI) flash. Both processors have tightly coupled memory (TCM) and an on-chip cache for performance while executing from external flash memory. The system Firmware Processor provides functions developed by Qualcomm Technologies International, Ltd. (QTIL). The Developer processor provides flexibility to the product designer to customize their product. The Audio subsystem contains a programmable Kalimba core running Qualcomm® Kymera™ system DSP architecture framework from read only memory (ROM). A range of audio processing capabilities are provided from ROM which are configurable in fully flexible audio graphs. The flexibility provided by the programmable applications processor plus the ability to configure the audio processor enables manufacturers to easily differentiate products with new features.
