Exploring the Ultra-Low Power Bluetooth Connectors: Silicon Labs BG22L and BG24L SoCs
Introduction to Silicon Labs' Innovations
Silicon Labs, a renowned leader in secure wireless technology, has set a new standard with the introduction of their latest System-on-Chips (SoCs)—BG22L and BG24L. Designed specifically for ultra-low power Bluetooth connectivity, these devices exemplify the convergence of advanced capabilities and energy efficiency. While the BG22L caters to traditional applications, the BG24L opens doors for innovative solutions in Artificial Intelligence (AI) and Machine Learning (ML) integration, marking a significant advancement in Bluetooth technology as we know it.
The BG22L: Enhancing Everyday Applications
The BG22L SoC is engineered to meet the needs of common Bluetooth applications, such as asset tracking tags and household appliances. Combining a competitive blend of robust security features, powerful processing capabilities, and optimal connectivity, this device represents an ideal choice for high-volume and cost-sensitive deployments. The design emphasizes low energy consumption, facilitating extended battery life that can reach up to ten years on a standard coin cell battery.
A standout feature of the BG22L is its ultra-low power receive mode, simplified further by a built-in Precision Low-Frequency RC Oscillator (PLFRCO). This innovation eliminates reliance on external oscillators, reducing production costs and physical footprint without sacrificing performance. Additionally, it boasts support for Bluetooth 5.4 and Direction Finding, broadening its application scope significantly.
Advancing AI and ML with BG24L
In contrast, the BG24L model is tailored for more demanding applications, providing support for developing AI-enhanced use cases. It incorporates an exclusive Matrix Vector Processor (MVP) for AI/ML tasks, enabling efficient processing capabilities. The BG24L is optimized for Bluetooth 6.0, featuring Channel Sounding technology which allows devices to gauge proximity with sub-meter accuracy. This is particularly advantageous in complex environments, enhancing asset tracking, geofencing, and even facilitating contactless access control solutions.
Leveraging the BG24L, applications range from efficiently locating personal items like keys to sophisticated usage in commercial settings such as distribution centers. The potential for automatic unlocking of vehicles or lockers, triggered solely by the presence of an authorized Bluetooth-enabled device, illustrates a groundbreaking shift in how we perceive security and convenience in our daily lives.
Performance and Efficiency
Both SoCs utilize an ARM Cortex M33 processor, with the BG24L clocking in at 78 MHz while the BG22L operates at a slightly lower 38.4 MHz. They feature generous memory configurations, with the BG24L housing 768 kB flash and 96 kB RAM, while the BG22L supports up to 352 kB flash and 24 kB RAM. Such specifications ensure smooth operation across various Bluetooth applications while optimizing power usage for extended durations.
