QCC5125 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-AB and Class-D audio drivers, advanced power management, Li-ion battery charger, light-emitting diode (LED) drivers, and flexible interfaces including interintegrated circuit sound (I²S), 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. In built capabilities in ROM, may be complimented or replaced by capabilities run from random access memory (RAM), including those provided by QTIL, the product designer or third parties. The flexibility provided by the fully programmable applications processor plus the ability to configure and program the audio processors enables manufacturers to easily differentiate products with new features. QCC5125 VFBGA is driven by a flexible, software platform with powerful integrated development environment (IDE) support. This enables rapid time-to-market deployment for a broad range of consumer electronic products, including audio, wireless speaker, Qualcomm TrueWireless, and broadcast audio for stereo speaker arrangements.
