Silicon Labs Announces New Bluetooth SoC and MCU Ideal for Small Form

Dec 30, 2023

AUSTIN, Texas, March 14, 2023 /PRNewswire/ — Silicon Labs (NASDAQ: SLAB), a leader in secure, intelligent wireless technology for a more connected world, today announced two new integrated circuit families designed for the smallest form factor IoT devices: the xG27 family of Bluetooth systems on chips (SoCs) and the BB50 microcontroller unit (MCU).

Designed for the smallest IoT devices, the xG27 and BB50 families range in size from 2 mm-squared, about the width of a #2 pencil lead, to 5 mm-squared, less than the width of a standard #2 pencil. These offer IoT device designers energy efficiency, high performance, trusted security, and in the case of the xG27 family, wireless connectivity. This makes the xG27 SoC family and BB50 MCU ideal for tiny, battery-optimized devices like connected medical devices, wearables, asset monitoring tags, smart sensors, simple consumer electronics like toothbrushes and toys, and more.

"Silicon Labs is the pure-play IoT leader, and our breadth, depth, and focus enable us to support the broadest range of wireless connectivity protocols of any semiconductor company," said Silicon Labs CEO Matt Johnson. "The xG27 SoCs and BB50 MCUs are helping developers build exciting new devices while also simplifying their development processes, all while maintaining the low-power and small form-factor requirements for extremely small devices."

xG27 SoC Connects One of World's Smallest Wearable Devices

The new xG27 family of SoCs comprises the BG27, for Bluetooth connectivity, and the MG27, supporting Zigbee and other proprietary protocols. Built around the ARM Cortex M33 processor, the BG27 and MG27 share several common features designed to make them the ideal SoC for small form-factor devices, including:

Lura Health, a medical device manufacturer and participant in the Alpha program for BG27, has already selected the new SoC to form the basis of its new in-development smart wearable. But unlike some of the most common wearables on the wrist or other external skin, the new Lura Health monitor goes in a person's mouth. Specifically, the device is so small that it is glued to a tooth. With the device, dentists and other clinicians can collect important data from saliva, which is used to test for over 1,000 health conditions.

"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. "We spent hundreds of hours searching for a microcontroller that meets our needs, and the BG27 is the only solution that checks every box."

The BG27 and MG27 open up and extend a wide range of possible applications and use cases. You can read blog posts detailing how the xG27 family enhances the smart home and connected health markets.

New BB50 8-bit MCUs Increase Design Flexibility While Reducing Cost and Complexity

While the IoT is built around connectivity, many devices do not need to be connected, and there are non-connected versions of connected devices.

For example, in commercial lighting, the application may need a simple control mechanism for the light based on ambient light or occupancy sensors. In the consumer goods space, many toothbrush manufacturers have recently built connectivity into their brushes, which provides users with friendly reminders and insights about their brushing patterns. However, some consumers still prefer non-connected versions of the device and simply want an electric toothbrush.

While, in theory, this seems like a simple problem to solve, it can often lead to inventory and SKU sprawl, with the non-connected version of a product being designed differently than the connected version. Add in different cosmetic effects like color or if the outer material is metal or plastic, and very quickly, management of inventory and various designs becomes costly and complex. Other devices like LED lighting, keypads, drones, toys, and anything with flashing lights or a motor still require a processor to control those essential functions, regardless of whether it is connected for added functionality.

The new BB50 MCU and the larger BB5x MCU family help address these challenges with the following:
