Silicon Labs Launches BG29 Bluetooth® LE Chip for IoT Devices
Austin, Wednesday, 12 March 2025.
Silicon Labs unveils the BG29 chip, enhancing Bluetooth® Low Energy tech for IoT devices with improved efficiency and security, available in compact packages suitable for healthcare applications.
Revolutionary Features for Miniature Devices
Silicon Labs’ announcement on March 11, 2025, introduces the Series 2 BG29 family of wireless SoCs with impressive technical specifications. The chip boasts 1 MB Flash and 256 kB RAM capacity, enabling advanced applications while maintaining ultra-low power consumption [1][2]. The BG29’s versatility is enhanced through its availability in two package options: the quad flat no-lead (QFN) and wafer-level chip scale packages (WLCSP), catering to different device form factors [1].
Advanced Power Management and Security
The BG29 incorporates sophisticated power management features, including an integrated DCDC boost converter that supports a wide voltage range, making it compatible with various battery types. A built-in Coulomb counter provides precise battery monitoring capabilities, crucial for medical and healthcare applications [2]. Security remains paramount, with the implementation of Silicon Labs Secure Vault™ High, designed for PSA Level 3 security certification, offering advanced encryption and authentication features [1][3].
Healthcare and IoT Applications
The BG29 is specifically engineered for integration into various healthcare devices, including insulin delivery patches, continuous glucose monitors, and smart tooth implants [1]. Beyond healthcare, the chip’s applications extend to industrial automation, asset tracking, and smart home sensors [2]. The compact WLCSP package is particularly suited for disposable medical devices and one-time use applications, while the QFN package targets larger devices such as pulse oximeters and heart rate monitors [1].
Market Availability and Future Impact
Silicon Labs, headquartered in Austin, Texas, and operating across 16 countries [2], has scheduled the BG29 family for general availability in Q3 2025 [1][2]. As a leading innovator in low-power wireless technology [4], Silicon Labs’ latest offering positions the company at the forefront of the IoT revolution, particularly in the rapidly growing connected health sector [2][3].
