First Built-In AI/ML Accelerator in Sub-Ghz
SoC Pushes Intelligence to Edge
AUSTIN,
Texas, June 8, 2023 /PRNewswire/ -- Silicon
Labs (NASDAQ: SLAB), a leader in secure, intelligent wireless
technology for a more connected world, today revealed the
new dual-band FG28 SoC, designed for long-range networks and
protocols like Amazon Sidewalk, Wi-SUN, and other proprietary
protocols. A dual-band SoC, the FG28 includes radios for
sub-Gigahertz (Ghz) and 2.4 Ghz Bluetooth LE, as well as a built-in
AI/ML accelerator for machine learning inference, as well as
Silicon Labs' industry-leading Secure Vault™ technology.
"The FG28 SoC addresses several key needs for our customers when
it comes to developing and deploying low-power wide area networks,"
said Daniel Cooley, CTO of Silicon
Labs. "By including Bluetooth, it gives users an easy way to
provision and deploy new devices onto the network, while the
sub-Ghz band is designed to support device communications over one
mile, allowing for new edge applications in areas like smart
agriculture, smart cities, and neighborhood networks like Amazon
Sidewalk."
Dual-Band Capabilities Allow Support for Multiple Protocols in
Single Design
As connectivity and computing power is being pushed further to the
edge, new emerging applications require solutions that can provide
a "Swiss army knife" of connectivity options. By providing sub-Ghz
connectivity using networks like Wi-SUN, the FG28 can serve as the
battery-operated end node in smart cities, for example, as a
tracker on dumpsters to help locate them and check the last time
they were emptied, or in irrigation systems across multi-acre
commercial farming operations, or as livestock trackers and health
monitors on sprawling ranches. Bluetooth connectivity not only
allows for devices to easily be deployed on the network, but also
allows for operators to connect to the device locally for
diagnostics, data downloads, and more. The FG28 SoC has several
additional features that can open new applications for sub-Ghz
devices:
- The industry's first integrated AI/ML hardware accelerator
in a sub-Ghz SoC, allowing for machine learning inference at
the edge to enable predictive maintenance warnings, monitor soil
conditions for key conditions like moisture and pH levels, and
more.
- 1024 kB of flash storage and 256 kB of RAM, to meet the
memory needs of a wide range of protocols and technology
stacks.
- Industry-leading Secure Vault Mid and High support to
better build trust in the device and allow designers to choose the
level of security they need for their applications.
- Energy-efficient radio core with low active and sleep
currents with fast wakeup times ideal for battery-operated end
nodes.
- Up to 49 General Purpose Input/Output (GPIO) pins for
robust peripheral connectivity.
Support for Amazon Sidewalk Pushes Connectivity Beyond the
Walls of the Smart Home
One of the more exciting developments in the IoT this past year was
the opening of Amazon Sidewalk for developers. Amazon Sidewalk is a
secure, ubiquitous, always-on community network built by the
community, for the community. Using existing smart home devices
like select cameras and speakers as gateways, Amazon Sidewalk
offers a secure, reliable, and versatile connection that supports
long-range use cases.
Developers and designers interested in developing for Amazon
Sidewalk using Silicon Labs can watch the on-demand replay of the
June 8 Tech Talk, "Designing Long
Range Devices with Amazon Sidewalk."
Get Started Now
The FG28 is currently sampling now with general availability
planned before the end of 3Q 2023. In addition, the FG28 will also
be available in derivatives for optimized for Amazon Sidewalk and
Z-Wave Long-Range, and as a stand alone MCU. Developers and
designers should contact their Silicon Labs sales representative to
learn more.
To stay ahead of the latest IoT trends and keep up with the
latest tools, protocols, and more, developers and designers can
also register for the Silicon Labs Wireless Training Tech Talks.
With tracks focused on Wi-Fi, Bluetooth, Matter, and LPWAN, the
sessions are free to watch both live and on-demand.
