Silicon Labs unveils Amazon Sidewalk optimised SoCs 

Two SoCs unveiled by Silicon Labs, the SG23 and SG28, are optimised for Amazon Sidewalk. 

To address the varied technologies and protocols that exist in the IoT today, the Silicon Labs portfolio includes different device families and derivatives for different parts, such as the BG line of Bluetooth SoCs and the ZG line of Z-Wave SoCs, and this latest addition, the SG family of SoCs optimised for Amazon Sidewalk. 

The always-on Amazon Sidewalk network uses Bluetooth LE for device provisioning and nearby device connectivity, sub-GHz FSK for connectivity up to one mile, and a proprietary CSS radio for extreme long range. Most Amazon Sidewalk end-devices will support Bluetooth LE and either FSK or CSS. The SG28 includes two dual-band SoCs with radios for both sub-GHz FSK as well as Bluetooth LE. These dual-band parts help simplify devices and reduce cost by including the two most commonly used radios on Sidewalk end devices in a single package. The SG23 provides security and a robust sub-GHz link budget for long range, end node devices. 

The company has also introduced developer tools as the company continues to work closely with Amazon to provide developers with the hardware, software, and development tools needed to navigate the Amazon Sidewalk development process.

Silicon Labs has worked directly with Amazon to create the Amazon Sidewalk Developer’s Journey, a guide with 12 steps organised in three stages, covering determining if a targeted region has Amazon Sidewalk coverage, device deployment and ongoing support for devices in the field. The guide includes technical documentation, videos, and code samples, with the option to engage a Silicon Labs expert for support. Silicon Labs provides all the tools needed for each step, and by following the Developers Journey, device makers are well-positioned for Amazon Web Services and Amazon Sidewalk certification and approval. 

Silicon Labs develops secure, intelligent wireless technology for a more connected world with an integrated hardware and software platform, intuitive development tools, ecosystem and robust support for building advanced industrial, commercial, home, and life applications.
