Qualcomm QCC5100 Series Bluetooth

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-low-power 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.
