With the booming development of the smart wearable device market, various products are gradually penetrating into daily life.REALTEKThe application of chips in smart wearable devices is extensive and profound. With advantages such as low power consumption, high performance, and high integration, chips play an important role in multiple fields such as smart watches, smart glasses, Bluetooth earphones, etc.

1、 Smart Watch

1. Ultra long battery life and multi-sensor support

Ruiyu's RTL8762DT chip achieves a 10 day battery life for smartwatches through ARM Cortex-M4F 32-bit CPU and low-power design. This chip integrates 38 GPIO interfaces and can connect various sensors such as photoelectric blood pressure, blood oxygen, heart rate, sleep, and exercise status to meet the needs of medical grade health monitoring. For example, the G28 Care medical grade smartwatch achieves multi-dimensional health data collection through this chip and enhances user experience through high-precision screen display.

2. Single chip integration and development convenience

Ruiyu's smart watch solution based on RTL8773E uses a single BT SoC as the main controller, which connects peripherals through interfaces such as SPIC, I2C, SPI, and supports Bluetooth connection to mobile phones. This solution provides a fully functional SDK development package, including product prototype engineering, mobile APP SDK, OTA tools, and production tools, significantly reducing customer development workload and accelerating project implementation.

2、 Smart glasses

1. Dual chip architecture and high-performance processing

Realtek's RTL8773D RTL8735B dual chip solution provides audio, video, and wireless connectivity capabilities for smart glasses. RTL8773D is responsible for communication, audio processing, and display operations, and supports Bluetooth 5.4 low-power connection; RTL8735B focuses on image processing and data storage, supports dual band Wi Fi and lens input, can take 12 megapixel snapshots and record 2K movies. Both enhance design flexibility and overall efficiency through modular division of labor.

2. Cross platform interaction and AI voice support

REALTEK creates cross platform solutions for smart glasses, providing an intuitive user experience. Users can manage shooting content through the app and use the built-in AI assistant to achieve multimodal interaction of voice, image, and gesture. In addition, the app integrates OTA wireless update mechanism to ensure continuous optimization of device functions.

3、 Bluetooth earphones

1. Low power consumption and high-quality audio transmission

Ruiyu's RTL8763 series chips support Bluetooth 5.4 dual-mode, enabling high-quality A2DP audio streaming and low-power LE Audio audio transmission. For example, its active noise reduction true wireless Bluetooth earphone solution integrates environmental noise reduction (ENC) and hybrid active noise reduction (Hybrid ANC) functions, greatly improving sound quality while maintaining ultra-low power consumption advantages.

2. Intelligent functions and convenient operation

The RTL8773B series chip supports Audio Pass Through, Google Fast Pairing, and voice assistant functions, enabling 7x24 continuous online, wake-up, and monitoring. In addition, the chip supports digital reverberation ANC, with a noise reduction effect of up to 40dB, and the power consumption when Hybrid ANC is turned on is less than 1mA.

4、 Wireless connectivity and multi scenario adaptation

1. Dual mode wireless communication and low-power design

REALTEK's XR871GT chip integrates Wi Fi 802.11b/g/n and Bluetooth 4.2 (BLE) dual-mode functions, supporting wireless communication in the 2.4GHz ISM frequency band. This chip uses an efficient CPU and microcontroller (MCU) to achieve multitasking parallel processing, and meets compact design requirements through a small QFN packaging form. Its low-power characteristics are particularly suitable for low-power application scenarios such as sensors, smart home devices, and smart watches.

2. High integration and secure communication

The XR871GT chip integrates Wi Fi and Bluetooth functions into a single chip, reducing hardware design complexity, lowering overall costs, and improving system reliability. This chip supports wireless communication security protocols such as WPA2, WPA3, AES encryption, etc., ensuring data transmission security. In Bluetooth low-power mode, secure pairing and encrypted communication between devices can be achieved.

REALTEK, with its technological strength and deep understanding of wearable device needs, has chip solutions covering various application scenarios of wearable devices and is playing an important role in the field of smart wearable device chips.
