Silicon Labs' BG22L and BG24L "Lite" SoCs Bring Application-Optimized Ultra-Low Power Bluetooth Connectivity

Silicon Labs introduced the BG22L and BG24L SoCs for Bluetooth^® LE connectivity, with "L" representing the new application-optimized Lite devices.

Optimized for common Bluetooth applications like asset tracking tags and small appliances, the BG22L brings the most competitive combination of security, processing power, and connectivity for high-volume, cost-sensitive, and low-power applications. The BG24L SoC includes the Silicon Labs accelerator for AI/ML applications and support for Bluetooth Channel Sounding for asset tracking and geofencing, even in the most crowded areas like packed warehouses and multi-family housing units.

Channel Sounding was one of the most exciting features when the Bluetooth SIG announced Bluetooth^® 6.0 in September 2024. It allows Bluetooth 6.0 devices like the BG24L SoC to use two-way connections to determine the distance between themselves within sub-meter accuracy. This opens a range of applications from item finding to access control. For example, users would be able to locate keys, wallets, or any other Bluetooth 6.0-equipped item at a fraction of the power of other ranging technologies. In commercial and industrial environments, Channel Sounding brings similar item-finding functionality to retail shelves, distribution centers, and more (more info).
