**Silicon Labs BG2B: A New Benchmark in Ultra-Low-Power Bluetooth for the IoT**
Silicon Labs has unveiled its latest innovation, the BG2B, a next-generation Bluetooth Low Energy (LE) System-on-a-Chip (SoC) designed to redefine the possibilities for battery-powered IoT devices. As a pioneer in low-power wireless connectivity, Silicon Labs has engineered the BG2B to address the evolving demands of modern applications, offering an unprecedented combination of power efficiency, security, and integrated functionality.
### A New Standard for Ultra-Low-Power Bluetooth
Battery life remains the cornerstone challenge for any portable or remote IoT device. The BG2B tackles this issue head-on with Silicon Labs’ lowest-power Bluetooth architecture to date. In comparison to its predecessors, the BG2B delivers a 14–15% reduction in MCU active current, lower Bluetooth receive current, and an incredibly low EM2 sleep current of just 1.1 µA with RAM retention.
This leap in efficiency directly translates to longer operational lifespans for a wide array of devices. Whether it’s wireless sensors, asset tracking tags, electronic shelf labels (ESLs), smart locks, wearables, or vehicle diagnostics tools, the BG2B empowers developers to build products that can operate for years on a single battery charge while maintaining a compact form factor.
### Enhanced Capabilities for Location-Aware and Secure Applications
As Bluetooth LE technology advances beyond simple data transmission, developers are tasked with integrating features like secure ranging and location awareness. The BG2B is specifically designed to meet these demands. It supports advanced Bluetooth Channel Sounding capabilities—including Mode 3, Normalized Attack Detector Metric (NADM), and Inline Phase Correction Term (Inline PCT)—which are designed to meet the stringent specifications of Apple and Google. This ensures seamless interoperability across the major mobile ecosystems.
Furthermore, the BG2B integrates a robust set of peripherals that streamline design and reduce overall costs. A standout feature is its integrated CAN-FD interface, which allows for wireless diagnostics and monitoring in commercial vehicles, fleet management systems, and industrial equipment, eliminating the need for a separate bridge device. For smart retail and electronic shelf labels, the inclusion of integrated LED boost and four-channel LED sink capabilities removes the requirement for external driver circuitry.
### Built for Tomorrow’s Security Requirements
In an era of increasing cybersecurity threats, the BG2B incorporates Silicon Labs’ Secure Vault™ technology. This hardware-based security feature is designed to protect critical assets such as device identity, firmware, cryptographic keys, and sensitive data. The BG2B is engineered to support PSA Level 3 compliance, helping manufacturers prepare for future regulatory requirements like the European Union Cyber Resilience Act. Through Silicon Labs’ Custom Part Manufacturing Service (CPMS), companies can also securely provision unique identities and credentials directly during the manufacturing process.
### Availability and Conclusion
The BG2B SoCs are currently available through an early customer engagement program, with initial production hardware, including modules, planned for 2027. For more detailed information, developers are encouraged to visit the official Silicon Labs blog.
**Conclusion**
The Silicon Labs BG2B represents a significant evolutionary step for Bluetooth Low Energy technology. By successfully merging ultra-low power consumption with advanced location-sensing capabilities and robust security, the BG2B provides a comprehensive solution for the next generation of IoT devices. It empowers developers to create smarter, more capable, and more reliable connected products that meet the demands of a increasingly connected world.
