Qualcomm DK-QCC3024-VFBGA90-A-0

The Qualcomm QCC302x/QCC303x/QCC304x/QCC305x/QCC307x SoC series are flash-programmable Bluetooth audio Systems-on-Chip (SoC) based on an ultra-low power architecture. Designed for the future of Bluetooth audio, they address the demand for powerful, feature-rich true wireless earbuds capable of all-day use. The series includes options supporting the LE Audio Bluetooth standard and benefiting from Snapdragon Sound technology. These SoCs feature highly integrated Bluetooth technology aimed at delivering a superior, refined user experience. QCC30xx SoCs offer powerful multi-core processing capability, designed to enable flexible innovation without extending development cycles. The QCC305x and QCC307x bring advanced Qualcomm technologies such as Qualcomm Adaptive ANC and digital assistants to a broad range of products, and are designed to support Snapdragon Sound technology. The series is engineered for ultra-high power efficiency, enabling the development of very compact, feature-rich earbuds with up to 16 hours of battery life from a 65mAh battery. The QCC307x is designed to support a range of LE Audio-enabled earbud use cases, including audio sharing and broadcasting, gaming mode, and stereo recording. These platforms deliver high-resolution (24-bit 96kHz) and low-latency audio through the Bluetooth audio processing chain. The QCC307x features Snapdragon Sound CD lossless audio, designed to dynamically extend the Bluetooth connection to deliver 16-bit 44.1kHz lossless audio. The QCC304x, QCC305x, and QCC307x support integrated ultra-low power digital ANC technology. The QCC307x is designed to support third-generation Qualcomm Adaptive ANC with a full-band ambient mode, delivering powerful, effective noise cancellation while providing listeners with a natural spatial awareness of their surroundings. The QCC305x and QCC307x support voice service activation via button press or wake word, designed to stream audio and transmit voice control functions to a smartphone for command processing and execution.
