Miniature Bluetooth LE SoC targets connected health applications
Featuring a compact footprint, the Series 2 BG29 family of wireless SoCs from Silicon Labs delivers high-end processing and Bluetooth LE connectivity in a tiny form without compromising performance.
The BG29 Bluetooth LE microcontroller features substantial memory with significant RAM and Flash capacities. It is ideal for advanced applications such as real-time data processing, complex algorithm execution, and high-speed communication protocols. The SoC additionally 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 transforming healthcare globally, yet miniaturisation without compromising performance or power continues to be a significant development hurdle. The BG29 overcomes this challenge by incorporating high-performance wireless technology, long battery life, large memory capacity, and multi-connection support into even the smallest devices, such as blood glucose monitors, where achieving this previously proved extremely difficult.
The BG29 is designed to handle miniature, high-performance, connected health applications. The human body is one of medical device makers’ most complex design challenges. It absorbs and reflects radio signals and disturbs antenna resonance, especially for small wearable devices that need to comply with strict regulatory guidance and specific absorption rate (SAR) limits. The BG29 Bluetooth LE SoC features the best-in-class radio sensitivity of –99.2 dBm, which is the most important characteristic of sending and receiving Bluetooth messages in in-body and on-body applications while saving device energy and battery.
The BG29 Bluetooth LE SoC is available in both WLCSP and QFN packages, delivering industry-leading connectivity for a wide range of wireless devices like connected health, asset trackers, and building automation. The WLCSP can be used for tiny devices like battery-powered sensors, insulin delivery patches, and one-time-use applications such as disposable continuous glucose monitors (CGMs) and smart tooth implants. Meanwhile, the QFN package is ideal for non-size-constrained device types such as pulse oximeters, access control, industrial automation and heart rate monitors.
With 1 MB Flash and 256 kB RAM, the BG29 SoC delivers superior performance and processing capabilities for advanced, demanding applications while ensuring low power consumption. The large memory keeps data tracking going even during long smartphone connection breaks. The BG29 enables Bluetooth LE for IoT devices such as portable medical devices, wearables, smart home sensors, asset trackers, and more.
An integrated DCDC Boost on the BG29 offers IoT device manufacturers a wide voltage range, facilitating the use of single-cell alkaline, silver oxide, and button cells while minimising the device’s form factor. The integrated Coulomb counter allows for precise battery level monitoring on portable medical devices, preventing battery depletion during critical health application usage and improving the user experience of other wearables and devices.
Secure Vault High with Virtual Secure Engine provides robust security capabilities, protecting the device against scalable local and remote software and hardware attacks by providing advanced encryption, secure key management, and authentication.
