Realtek's Dual-Mode BT SOC series is a single-chip solution that integrates RF, PMU, CODEC, USB, high-performance CPU, and DSP, while also providing a rich set of IO interfaces. It boasts powerful computational capabilities, supports multiple algorithms, and simultaneously supports dual-mode Bluetooth (classic Bluetooth and Bluetooth Low Energy) as well as BLE audio technology, providing users with stable and reliable wireless transmission. For applications that require high-speed data transmission and low-power, small data transmission, the SOC series offers flexibility and reliability.
The SOC series finds wide applications in various fields that require wireless connectivity, audio processing, and image display functions, such as open wireless earphones (OWS), stereo headphones, gaming headphones, speakers, wearable devices, charging cases with smart screens, and smart dashboards, among others. Realtek also meets the diverse needs of different customers by offering differentiated solutions in terms of package size, GPIO count, SDK tools, audio algorithms, image processing algorithms, power management, and amplifiers.
With its high integration, strong computational capabilities, stable and reliable wireless transmission, and flexibility, the SOC series provides users with high-performance solutions in various application domains.
