QCC-730-1-WLPSP90-HR-03-0-02

RF Transceiver ICS Overview

The Qualcomm QCC730 is a Bluetooth audio system-on-chip designed for premium wireless earbuds and headsets. It integrates the Qualcomm aptX Adaptive codec, enabling high-fidelity audio with dynamic bitrate adjustment between 279kbps and 420kbps to balance quality and latency. The platform supports multipoint connectivity, allowing simultaneous pairing with two devices, and features Qualcomm TrueWireless Mirroring for independent left-right channel operation. It includes a dedicated Hexagon DSP for noise cancellation and voice isolation, supporting up to four digital MEMS microphones. The chip utilizes a low-power architecture optimized for extended battery life in compact form factors.

RF Transceiver ICS Procurement Notes

Verify that the specific suffix HR-03-0-02 matches the required package type and temperature grade for your design. Confirm compatibility with your chosen antenna design and external memory configuration. Ensure that the supplier provides valid traceability documentation for this specific variant. Cross-reference the part number against the latest datasheet to confirm pinout and electrical specifications before finalizing procurement orders.

RF Transceiver ICS Selection Notes

Select this component when high-fidelity audio transmission is critical alongside low-latency performance requirements. It is suitable for designs prioritizing battery efficiency through TrueWireless Mirroring technology. Consider this chip if your application demands robust noise cancellation capabilities using multiple microphone inputs. Evaluate the need for multipoint connectivity as a primary feature for user convenience in dual-device scenarios.

RF Transceiver ICS Part Context

The QCC730 belongs to Qualcomm’s second-generation Bluetooth audio platform, succeeding earlier QCC series chips. It represents an evolution in mobile audio connectivity, focusing on enhancing user experience through improved codec support and power management. This series is widely adopted in mid-to-high-end audio peripherals, bridging the gap between basic Bluetooth functionality and audiophile-grade wireless performance standards.

RF Transceiver ICS Replacement Considerations

Check for direct pin-compatible upgrades within the QCC51xx or QCC30xx series depending on feature requirements. Verify software stack compatibility if migrating from older Bluetooth controllers. Ensure that any substitute part supports the same aptX variants and microphone interface configurations required by your existing hardware design.
