Ultra-small SoCs with ultra-low power for connected health devices

Silicon Labs has announced its new Series 2 BG29 family of wireless SoCs, developed to bring high compute and connectivity to the smallest form factor BLE devices without compromising performance. The new series is ideal for today's most intensive BLE applications like wearable health and medical devices, asset trackers, and battery-powered sensors.

The series is available in compact QFN and WLCSP, providing substantial memory with significant RAM and Flash capacities. These extended memory resources allow advanced applications such as real-time data processing, complex algorithm execution, and high-speed communication protocols.

It features a DC-DC boost for wide voltage range support, a Coulomb counter for accurate battery monitoring, and Silicon Labs Secure Vault High designed for PSA Level 3 to protect sensitive data.

Smart medical devices are transforming healthcare globally, but miniaturisation – building smaller connected devices without sacrificing performance or power – remains a key development obstacle. The BG29 represents a significant breakthrough. It integrates high-performance wireless, long battery life, large memory capacity, and multi-connection support in even the smallest devices, like blood glucose monitors, where it was previously extremely challenging.

"With the BG29, developers don't have to settle," said Jacob Alamat, senior vice president for the Home and Life business unit at Silicon Labs. "We're combining high connectivity and performance with small size and exceptional security – empowering device makers to break records in tiny connectivity."

The BG29 family of devices is expected to become available in Q3 of 2025.
