While Telink’s SoCs offer a fantastic solution for advanced IoT products, they’re also a great option for those that rely on more simple communication methods.

With the rapid development of science and technology, smartphones have become an indispensable electronic product in our daily work and life, making communication increasingly convenient. However, in certain scenarios, such as large-scale venue management, catering services, property security, and outdoor activities, walkie-talkies still have incomparable advantages, as they do not need to be connected to mobile communication signals. As such, walkie-talkies can be used in areas without signal coverage, providing better instant call efficiency and lower communication costs than mobile phones.

Recently, 52Audio Network disassembled Xiaomi’s new Walkie-Talkie 2S and found that it uses the Telink Semiconductor TLSR9515R multi-standard wireless SoC as its main control chip. This series of SoCs provides highly integrated, ultra-low power applications for audio products and supports Bluetooth^® 5.3, Basic Data Rate (BR), Enhanced Data Rate (EDR), and other industry standards, effectively helping enhance market competitiveness.

The Xiaomi Walkie-Talkie 2S motherboard uses Telink’s TLSR9515R multi-standard wireless SoC. In addition, it uses RF transceiver chips, audio power amplifiers, power management chips, backlight dimming chips, dual operational amplifiers, FM receivers, and other components.

Telink’s TLSR9515R multi-standard wireless SoC meets industry alliance specifications and supports the standards set by Bluetooth 5.3, Basic Data Rate (BR), Enhanced Data Rate (EDR), Bluetooth^® LE, indoor positioning, and Bluetooth^® LE Mesh. It also integrates 32-bit RISC-V MCU, DSP, ISM radio, 256KB SRAM, 1MB flash memory (TLSR9515A), 2MB flash memory (TLSR9515R), or external flash memory (TLSR9515D), analog and digital microphone inputs, AUX ADC, PWM, flexible IO interface, and other functions. In addition, TLSR9515R offers excellent low-power consumption performance.

The TLSR9515 series adopts a multi-level power management design to achieve ultra-low power operation, making it suitable for various types of battery-powered devices with limited power. The chip is highly integrated and requires only a few external components, allowing BOM cost savings.

52Audio Network also discovered that the Soundcore VR P10 true wireless VR headset, Saramonic Blink500 ProX B2 wireless microphone, SmallRig Wave W1-C wireless lavalier microphone, Razer Wolverine V2 Pro wireless game controller, and more use Telink’s multi-standard wireless SoC solution.
