Realtek Semiconductor Corp. is proud to announce its revolutionary portfolio of smart healthcare innovations at MEDICA 2025, setting new benchmarks in AI-driven health technology and connected medical devices.

AI Hearing Aid and Hearing Glasses Solutions

Realtek drives innovation in advanced wearables with its industry-leading AI hearing aid and hearing aid glasses solution, powered by the RTL8773DO-VHA chip. This platform features an ARM Cortex-M4, dual-core Cadence DSP, and six digital microphones (for binaural capability), delivering powerful AI noise reduction and voice processing. Trained on 15 million noisy scenarios, the AI ensures users experience remarkable speech clarity even in challenging acoustic conditions. The solution’s AI accurately captures the wearer’s voice while filtering out background noise. Own Voice Reduction technology minimizes acoustic discomfort from occlusion effect and self-voice amplification. With support for the NAL-NL2 industry-standard compensation protocol and up to 24-channel Wide Dynamic Range Compression, the system delivers precise hearing compensation at a prescription hearing aid level. Developers benefit from a comprehensive phone app SDK, enabling rapid integration of at-home hearing tests and self-fitting OTC/prescription hearing aids for a complete turnkey solution.

Smartwatch, Smart Band, and Smart Ring Solutions

Realtek’s wearable lineup harnesses advanced low-power Bluetooth SoC technology. The smart band and smart ring leverage RTL8762C and RTL8762E chips, respectively, for ultra-low power consumption and extended battery life. Powered by the RTL8773E, the smartwatch integrates a suite of interfaces (SPIC, I2C, SPI, GPIO, I8080, MIC, DAC) and connects to smartphones via Bluetooth for real-time health and activity tracking. The IC incorporates a 2.5D hardware graphics engine for advanced rendering while the CPU and DSP enable robust sensor algorithms, peripheral device control, and high-performance voice/audio processing. Comprehensive reference designs, SDKs, and toolchains streamline the development of these highly integrated wearable solutions.

Smart Charging Case — Next-Level Control and Connectivity

Realtek’s smart charging case solution redefines wearable device management, offering not only reliable charging but also an intelligent interface that transforms user interaction with audio devices. Leveraging Bluetooth connectivity, the solution ensures seamless integration between earbuds/headsets and smartphones, becoming a crucial information bridge. The Realtek chipset supports I2S, USB, ADC, SDIO, SPDIF, and QSPI interfaces, delivering low power, robust Bluetooth connections. From entry-level to premium charging cases, this platform empowers manufacturers with versatility and strong technical support. Realtek also offers full development kits and detailed documentation for efficient product design, testing, and rapid market launch.

BLE SoC Miniaturized Smart Medical Platform — Empowering Next-Generation Health Monitoring

Realtek’s BLE SoC medical solutions, centered around the RTL8762C series, combine industry-leading low power and rich interfaces, creating optimal platforms for next-generation miniaturized medical devices—even those using tiny or disposable batteries. SPI/QSPI display drivers, AMIC/DMIC audio input, and high-precision ADCs allow seamless, single-chip integration for products such as pulse oximeters, digital stethoscopes, and temperature patches. For continuous glucose monitoring, the Realtek RTL8762J BLE SoC is purpose-built for ultra-compact, low-power CGM devices. Its 2.78mm x 2.86mm WLCSP package dramatically reduces PCB area, delivering 15 days’ operation from a 20mAh coin cell and supporting 1.0V–3.6V operation—ideal for the world’s thinnest silver oxide batteries. This innovation enables CGMs that are even slimmer and more comfortable, setting new benchmarks for the user experience.

Realtek’s vision for the future of healthcare seamlessly integrates AI, connectivity, and power efficiency—delivering comfort, performance, and reliability for medical and consumer health applications.
