Qualcomm QCC5171 audio SoC - QCC-5171-0-WLNSP99-TR-040

A premium tier, ultra-low power, single-chip audio platform with a programmable DSP, optimised for use in truly wireless earbuds and hearables.

Qualcomm® QCC5171 is designed for the future of wireless sound, with support for LE Audio use cases and CD-Lossless (16-bit 44.1kHz) audio with Snapdragon Sound™ technology - our optimised chain of superior audio, connectivity, and mobile innovations.

Integrated features include our third generation Qualcomm® Adaptive Active Noise Cancellation (ANC), with full-band ambient mode for strong, effective noise cancellation and a natural feeling of spatial awareness. 

With Qualcomm® aptX Adaptive Audio, and high-performance DACs the platform is designed to deliver high resolution (24-bit 96kHz) and low latency audio through the Bluetooth audio processing chain.

This dual-mode platform brings LE Audio use cases for audio sharing, gaming and stereo recording supported alongside traditional Bluetooth tech, for the best listening experiences in a wide range of environments.

As consumer demand for smaller form factor devices continues to grow, the QCC5171 WLCSP package is designed to help manufacturers develop ultra-small earbuds that are comfortable enough to be worn for long periods of time.

These dual-mode platforms integrate the best of LE Audio and the best of classic Bluetooth, to enable smooth feature adoption for real-world listening scenarios.

Excellence in audio

QCC5171 is designed to offer a selection of options for delivering crystal-clear voice calls in earbuds. These include super wide band voice quality with aptX Voice technology, and up to 3-microphone Qualcomm® cVc™ Echo Cancelling and Noise Suppression (ECNS).
This platform also supports both 24-bit 96kHz and 24-bit lossless audio quality in an adaptive platform, along with low-latency Bluetooth audio for gaming.

Integrated noise cancellation

QCC5171 supports our third-generation Qualcomm ANC, which leverages an integrated, dedicated hardware block on the platform. It supports incredibly low-latency and low-power performance for noise cancellation, without taxing the audio subsystem. This tech is designed for increased bit-depth and sample rates, allowing more precise filter control so audio developers can tune for stronger noise cancellation across a wider range of frequencies.

Concurrent support for differentiating audio features

Differentiate at a range of consumer price points with concurrent support for our portfolio of licensable audio technologies , including Snapdragon Sound, digital assistants, Qualcomm ANC, aptX Adaptive Audio, aptX Voice technology, cVc. QCC5171 is designed to support wireless earbuds, stereo headsets and speakers with the audio features consumers need most, and to seamlessly shift between them.
