On July 5th, 2018, the leading semiconductor component distributor dedicated to the Asia-Pacific region---Lianda Holdings announced that its subsidiary, Qualcomm, launched the QCC5100 series of high-performance, low-power audio platforms for Qualcomm, supporting TWS Bluetooth headset and speakers. The QCC5100 series of breakthrough Bluetooth system-on-chips (SoCs) can support the next generation of Qualcomm TrueWireless technology. Compared with previous generation devices, this series of SoCs can reduce power consumption by 65% ​​in terms of voice calls and music streaming. This fully integrated single-chip solution uses a 4mm x 4mm chip scale package (CSP) to provide manufacturers with an efficient way to control and manage true wireless connections in earbuds. Its supporting audio development kit can support the development of next-generation highly compact and feature-rich wireless earplugs and ear-worn devices. component QCC-5121 (CSP) QCC-5120 (BGA) QCC-5124 (BGA) Figure 1-The system architecture diagram of the QCC5100 series of Qualcomm high-performance, low-power audio platform launched by Dalian Daquanding Product specifications Support Bluetooth 5.0 (2Mbps Bluetooth low energy consumption); Powerful quad-core processor architecture: dual-core 32-bit processor application subsystem, dual-core Qualcomm®KalimBA™DSP audio subsystem, embedded ROM+RAM and external Q-SPI flash memory; Audio subsystem: dual 120 MHz 32-bit Qualcomm® KalimBA™ DSPs, which can save power at 80MHz, 32MHz or 2MHz.
