QCC5121

QCC5121

Extremely low power premium tier Bluetooth Audio SoC in a WLCSP package, designed for use in compact, feature rich wire-free earbuds, hearables and headsets.

The Qualcomm® QCC5121 System-on-Chip (SoC) is designed to meet consumer demand for robust, high quality, wireless Bluetooth listening experiences in small devices with low power consumption for longer audio playback.

QCC5121 architecture is engineered for high performance with low power consumption. Power consumption can be reduced by up to 65 percent compared to our previous technology, for both voice calls and music streaming and devices are optimized to support longer audio playback in virtually all operating modes.

The flexibility provided by the programmable applications processor and audio DSPs helps manufacturers to easily differentiate products with new features without extended development cycles. QCC5121 is designed to support voice assistant through cloud services.

QCC5121 features digital active noise cancelling (ANC) technology integrated in the SoC, designed to eliminate the need for an external ANC solution. With Qualcomm TrueWireless™ technology, QCC5121 is engineered to deliver improved robustness and more evenly balanced power distribution between both earbuds, supporting longer playback time.

QC5121 is a part of the QCC5100 Low Power Bluetooth Audio SoC Series.

Qualcomm QCC5121 is a product of Qualcomm Technologies, Inc., and/or its subsidiaries.
