Silicon Labs announces Bluetooth SoC and MCU for small form-factor devices
Summary
Built around the ARM Cortex M33 processor, the BG27 and MG27 share several common features designed to make them the suitable SoC for small form-factor devices, including: • Wafer-level Chip Scale Packaging as small as 2.3mm x 2.6mm, suitable for compact and unobtrusive devices like medical patches, continuous glucose monitors, wearable electrocardiograms, and asset tags in various settings like retail and agriculture. • Shelf Mode that reduces energy use to less than 20 nano amperes so that devices can be transported and stocked on shelves while maintaining nearly full battery life for the end-user. Lura Health, a medical device manufacturer and participant in the Alpha program for BG27, has already selected the SoC to form the basis of its in-development smart wearable. “The BG27 is amazing because it’s small enough that we can develop an IoT sensor smaller than a tooth, the power consumption is low enough to remove battery life as a product constraint, it has enough memory to store a sophisticated firmware application, it allows us to perform the data analysis required to gain insightful information from what we are monitoring, and it has all the peripherals we need to interface with our sensors,” said Noah Hill, co-Founder and CTO of Lura Health. Add in different cosmetic effects like colour or if the outer material is metal or plastic, and very quickly, management of inventory and various designs becomes costly and complex.
