Miniature Bluetooth LE SoC for Connected Health Applications

Introducing the Series 2 BG29 family of wireless SoCs from Silicon Labs, featuring a compact footprint that delivers high-end processing and Bluetooth LE connectivity without compromising performance. The BG29 Bluetooth LE microcontroller boasts substantial memory with significant RAM and Flash capacities, making it ideal for advanced applications such as real-time data processing, complex algorithm execution, and high-speed communication protocols. Additionally, the SoC supports a wide voltage range, includes a Coulomb counter for precise battery monitoring, and features the Silicon Labs Secure Vault™ High, designed for PSA Level 3 to safeguard sensitive data.

Smart medical devices are revolutionizing healthcare globally, but miniaturization without sacrificing performance or power remains a significant challenge. The BG29 overcomes this hurdle by integrating high-performance wireless technology, long battery life, large memory capacity, and multi-connection support into even the smallest devices, like blood glucose monitors. This advancement addresses the difficulty previously faced in achieving such capabilities in compact devices.

Designed to cater to miniature, high-performance, connected health applications, the BG29 Bluetooth LE SoC tackles the complexities of designing medical devices for the human body. With its best-in-class radio sensitivity of –99.2 dBm, the SoC ensures efficient sending and receiving of Bluetooth messages in in-body and on-body applications while conserving device energy and battery life. This feature is crucial for compliance with regulatory guidelines and specific absorption rate limits.

The BG29 Bluetooth LE SoC is available in both WLCSP and QFN packages, offering industry-leading connectivity for various wireless devices such as connected health tools, asset trackers, and building automation systems. The WLCSP is suitable for tiny devices like battery-powered sensors, insulin delivery patches, and disposable continuous glucose monitors (CGMs). On the other hand, the QFN package is ideal for non-size-constrained devices like pulse oximeters, access control systems, industrial automation equipment, and heart rate monitors.

Equipped with 1 MB Flash and 256 kB RAM, the BG29 SoC provides superior performance and processing capabilities for demanding applications while ensuring low power consumption. The ample memory enables continuous data tracking even during extended smartphone connection breaks. The BG29 facilitates Bluetooth LE connectivity for IoT devices such as portable medical devices, wearables, smart home sensors, and asset trackers, enhancing their functionality and efficiency.
