TLSR952x Series TLSR951x Series

TLSR951x Series

The TLSR951x is a dual-mode Bluetooth audio System-on-Chip (SoC) that accommodates both classic Bluetooth audio and low-energy Bluetooth audio within a single integrated solution, effectively addressing the diverse requirements of end products for established technologies as well as emerging standards. This series of chips features a robust 32-bit RISC-V microcontroller unit (MCU), enabling the development of an extensive array of headsets and wearable devices. Furthermore, by leveraging Telink's proprietary ultra-low latency protocol, it facilitates the creation of wireless audio devices such as esports headsets and microphones that demand stringent playback latency performance.
