Technology Trends in Ultra-Low-Power Bluetooth SoCs
A New Benchmark for Power Consumption: Sleep Current as Low as 1.1 µA
Taking Silicon Labs’ BG2B as an example, its EM2 sleep current is only 1.1 µA (while retaining RAM data). Combined with a dual-channel output DC-DC power supply architecture, this enables IoT devices powered by button batteries to achieve an operational lifespan of over 10 years.
Bluetooth Channel Sounding: Secure Ranging and Location Awareness
The Channel Sounding feature introduced in the Bluetooth 6.0 core specification provides high-precision, secure ranging capabilities for asset tracking, electronic shelf labels (ESL), and vehicle diagnostics. The BG2B supports a complete Channel Sounding solution and complies with Apple and Google interoperability specifications.
High Integration: Reduced BOM Costs and PCB Area
The new generation of Bluetooth SoCs integrates a wide range of peripherals—including a power management unit (PMU), battery charger, LED driver, CAN-FD, and ADC—into a single chip, significantly reducing the need for external components. For example, the DA147x series integrates a 2D GPU and display support, making it suitable for advanced wearable HMIs.
