Telink Auracast™ Broadcast Audio Solution

As the centerpiece of the new LE Audio Bluetooth standard, Auracast™ Broadcast Audio allows devices like phones, PCs, and TVs to beam audio to an infinite number of receivers. This technology ensures high-quality audio delivery to everything from earbuds to hearing aids.

It significantly improves the audio experience in public venues and sharing scenarios. It is designed with Wi-Fi-like flexibility, supporting both open broadcasting for any user and secure, encrypted transmissions that require a password for access.

Telink’s TL751X, TL721X, and TLSR952X chip series now fully support the new Auracast™ broadcast audio feature. Powered by Bluetooth 5.4/6.0, powerful RISC‑V architectures, and ample memory, these SoCs maximize Auracast™’s potential for low-latency, high-quality, and collaborative sound. They offer a ready-to-market solution for products like TWS headphones, speakers, and public audio systems.

Telink Full-Duplex Wireless Cycling Intercom Solution

Designed for cycling and the outdoors, the full-duplex wireless intercom is a dedicated instant messaging solution. It meets the need for real-time group communication and adapts easily to cycling helmets, outdoor radios, and wireless headsets. Unlike conventional half-duplex systems, this solution delivers stable connectivity, low latency, and superior audio quality. Its real-time two-way communication ensures smooth and effective coordination for any outdoor team.

The Telink TL721X Full-Duplex Wireless Cycling Intercom Solution features an ultra-low-power design with operating currents as low as 1mA. It is powered by a 240MHz RISC-V MCU integrated with DSP/FPU, 512KB SRAM, and 2MB Flash, supporting local AI algorithms and high-performance edge computing.

It has achieved Bluetooth 6.0 certification and supports Apple Find My and Google Nearby, allowing for seamless integration into global location service ecosystems.
