UNISOC RDA5981 is a low power MCU that is a high performance solution for Wi-Fi smart speakers and Wi-Fi smart homes. With ARM Cortex-M4 core, mbed OS and secure network protocol stack, the chipset supports voice recognition on demand for audio resources such as Badiu Music, Himalayan, Qingting FM, and Beva Childern’s song. Encryption method (DLNA, Qplay) alongside QFN-40 encapsulation are included, providing improved memory storage, extended frequency range, and increased performance.

For the highest integration level, the external storage can be expanded up to 128GB and works with external PSRAM up to 32Mb. Customer app support for Smart Link, WeChat Airkiss, Bluetooth, and other network configuration helps the manufacturer to reduce the time to market.
