Extremely low-power, premium-tier SoCs designed for compact, feature-rich wireless earbuds, headsets and speakers.
QCC5100 is a family of breakthrough Bluetooth® audio System-on-Chips (SoCs) based on a low-power architecture. This series is designed to meet consumer demand for robust, high quality, wireless listening experiences in smaller devices with low power consumption for longer audio playback.
QCC5100 series architecture is engineered for low-power performance. Power consumption
can be reduced by up to 73 percent compared to our earlier Qualcomm® CSR867x, and is
optimized for demanding use cases so as to support longer battery life in virtually all operating modes.
The flexibility provided by the programmable applications processor and audio DSPs helps manufacturers to differentiate their products with new features. The SoCs are designed to support cloud-based voice assistants through the voice assistant’s respective cloud services.
The QCC5100 series features ultra-lowpower digital active noise cancelling (ANC) technology integrated in the SoC, designed to eliminate the need for an external ANC solution. This feature can help reduce the complexity, cost and PCB space needed for adding ANC to earbuds, hearables and other portable audio devices.
With Qualcomm TrueWireless™ Stereo technology, the QCC5100 family is engineered to deliver robustness and a sophisticated user experience. Our latest Qualcomm TrueWireless Mirroring improves robustness even further,offering dynamic bud-to-bud role-swapping with Bluetooth address handover, and also evens out power distribution between both earbuds.
Highlights
Quad-core processing
Quad-core processing architecture provides two application processors and two DSP units, designed to allow for an extensive degree of parallel processing, supporting the delivery of user experiences not possible using previous generation devices.
Ultra-low power
The QCC5100 series is designed for unprecedented efficiency in power consumption compared to our previous technology. These SoCs support the development of very small form factor, richly-featured earbuds that can be used for up to 10 hours with a 65mHA battery.
High quality wireless audio
Qualcomm® aptX™ Audio, aptX HD and aptX Adaptive audio
technologies are designed to deliver consistent, high-quality audio streaming over Bluetooth. The internal 24-bit endto-end audio pipeline and high-performance DACs support high resolution audio through the audio processing chain.
Qualcomm TrueWireless Mirroring
The Qualcomm® QCC514x devices feature Qualcomm TrueWireless Mirroring, a new topology that combines the best of our eavesdropping and relay solutions to deliver robustness while also supporting role-swapping and bud-tobud Bluetooth address handover, dynamically with virtually
no audio interruption.
Innovative, customizable platform
The QCC5100 audio platform includes a comprehensive and customizable Audio Development Kit (ADK) and several example designs that help to address the key challenges faced when developing products.
