Silicon Labs Unveils BG2B, Its Lowest-Power Bluetooth LE SoC with Industry-Leading Power Efficiency, Security, and Integration
Bluetooth® 6 SoC combines Channel Sounding, Secure Vault™ High security, and integrated CAN-FD and peripherals to enable smaller, longer-lasting IoT devices with lower system cost
As Bluetooth LE applications become more sophisticated, developers are challenged to add capabilities such as secure ranging, location awareness, advanced security, and richer peripheral integration while preserving battery life and compact designs expected of today's wireless IoT devices. BG2B addresses these demands with
Designed for applications including secure ranging, asset tracking, electronic shelf labels (ESLs), smart home, industrial monitoring, and vehicle diagnostics, BG2B helps developers extend battery life while preparing for more demanding Bluetooth LE applications.
"Bluetooth LE is moving beyond basic connectivity into secure ranging, proximity awareness, and location-aware experiences, while customers still need the low power, small form factor, and cost efficiency that made Bluetooth the foundation of battery-powered IoT," said
A New Standard for Ultra-Low-Power Bluetooth
Battery life remains one of the biggest challenges for battery-powered IoT devices as products continue adding more sensing, intelligence, and wireless capabilities. BG2B features a dual-output DC-DC power architecture and multi-core design that significantly improves efficiency across active, receive, and sleep modes.
BG2B is the lowest-power Bluetooth LE device in
Enhanced Channel Sounding with Expanded Peripherals
For developers building location-aware products today, BG2B supports advanced Bluetooth Channel Sounding capabilities including Mode 3, Normalized Attack Detector Metric (NADM), and Inline Phase Correction Term (Inline PCT). Designed to meet Apple and Google Bluetooth Channel Sounding specifications, BG2B helps developers build interoperable products across the industry's leading mobile ecosystems, supported by
Building on previous Silicon Labs Channel Sounding solutions, BG2B delivers even lower energy per ranging event through shorter Channel Sounding step timings, lower active current, and lower Bluetooth LE receive current.
In addition, BG2B integrates a broad set of peripherals that simplify system design while reducing BOM cost and PCB area.
The SoC combines Bluetooth LE with integrated CAN-FD, enabling wireless diagnostics and monitoring for commercial vehicles, fleet management, industrial equipment, and maintenance applications without requiring a separate Bluetooth bridge device.
Integrated LED boost and four-channel LED sink capabilities eliminate external LED driver circuitry, making BG2B well suited for electronic shelf labels, smart retail devices, and battery-powered products requiring RGBW LED for status indication.
Additional integrated capabilities include dual 12-bit ADCs for simultaneous analog sampling, Variable Resistive Load (VRL) for more accurate battery health estimation, to go along with expanded memory and a broad set of communication peripherals helping developers build more capable IoT devices while reducing external components.
Built for Tomorrow's Security Requirements
As connected devices face increasingly stringent cybersecurity requirements, BG2B incorporates
Designed to support PSA Level 3 compliance, BG2B helps manufacturers prepare for evolving security requirements such as the European Union Cyber Resilience Act. Combined with
Availability
BG2B SoCs are currently available through an early customer engagement program. Initial production hardware, including modules, are planned for 2027.
