Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Shenzhen Mingjiada Electronics Co., Ltd. introduces the Qualcomm IoT-QCC5121 extremely low-power, high-end Bluetooth audio SoC in WLCSP package designed for compact, feature-rich, hands-free earbuds, listenable devices and headsets.

QCC5121 Overview:

The Qualcomm® QCC5121 system-on-chip (SoC) is designed to meet consumer demand for a robust, high-quality, wireless Bluetooth listening experience in small form factor devices with low power consumption for longer audio playback.

The QCC5121 architecture is designed for high performance and low power consumption. Power consumption for voice calls and music streaming can be reduced by up to 65% compared to our previous technology, and the device is optimised to support longer audio playback in virtually all operating modes.

The flexibility provided by programmable application processors and audio DSPs helps manufacturers easily differentiate their products and implement new features without extending development cycles. the QCC5121 supports voice assistants through cloud services.

The QCC5121 has digital active noise cancellation (ANC) technology integrated into the SoC, designed to eliminate the need for external ANC solutions. With Qualcomm's TrueWireless™ technology, the QCC5121 supports longer playback times by providing increased robustness and more balanced power distribution between the two earbuds.
