Small (In Size) but Mighty for Connected Health Applications
Silicon Labs is annoucing a new family of low-power SoCs that enables secure, energy-friendly multiprotocol wireless networking for IoT devices
The announcement entails a new family of low-power SoCs that enables secure, energy-friendly multiprotocol wireless networking for IoT devices, the EFR32xG27, which includes the MG27, our multiprotocol SoCand the BG27, our Bluetooth LE SoC. The BG27 enables device makers to add high-performance and secure low-power Bluetooth LE on tiny form-factor devices, expanding the possibilities of smart connected medical devices and wearables.
Connected health devices are critical for remote care services, reducing healthcare costs, preventing the viral spread of diseases, and allowing more people to access care while at home. The BG27, in wafer-level chip scale packaging (WLCSP) with the dimensions of just 2.6 x 2.3 mm, is designed to help medical device makers put high-performance Bluetooth LE connectivity on even smaller and more challenging device form-factors – such as the smart tooth implant – increasing revenue opportunities through differentiation, new market categories, and higher buyer appeal.
Most connected wearables and portable medical devices need to accurately track people’s biometric data, allowing healthcare providers to monitor patients remotely, track progress and intervene when necessary. The lifetime of medical devices is crucial here, as it can vary from days to months to years of stocking and use. The BG27 features an integrated DCDC Boost that allows operation down to 0.8 volts, thus enabling the use of single-cell alkaline, silver oxide, and 1.55v button cell batteries typically used on medical applications such as battery-operated patches, wearable electrocardiograms (ECG), and continuous glucose monitors (CGM). In addition, the wakeup pin on the BG27 allows products to spend months in warehouses and transport, consuming less than 20 nA, until awoken, ensuring the battery remains fully charged when the device is needed the most. To prevent unexpected battery depletion during the use of critical health applications, the integrated Coulomb Counter on the BG27 enables accurate battery level tracking to enhance user safety and experience.
The BG27 provides device makers with a unique combination of features required to enable untethered, high-performance Bluetooth LE on extremely small devices, such as lifeline and life safety medical devices, with an extended battery capacity, as well as robust security to protect the device and user from rapidly evolving cyber-threats.
