New family of systems on chips (SoCs) optimized for Amazon Sidewalk

New family of systems on chips (SoCs) optimized for Amazon Sidewalk Door: Alcom Electronics B.V.

The SG23 and SG28 SoCs, as well as an extensive developer journey that provides step-by-step direction and expert advice for Amazon Sidewalk development. With these new devices, developer tools, and the previously announced Silicon Labs Pro Kit for Amazon Sidewalk, Silicon Labs strengthens its complete development platform for Amazon's rapidly growing network.

With the extensive breadth of technologies and protocols that exist in IoT today, there is no one-size-fits-all approach to choosing the right development platform for a device. As a leader in IoT, Silicon Labs has built its portfolio around that mindset, with different device families and derivatives for different parts, like the BG line of Bluetooth SoCs and the ZG line of Z-Wave SoCs, and now, the SG family of SoCs optimized for Amazon Sidewalk.

The always-on, community-driven Amazon Sidewalk network uses three different radios: 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 one of the two long-range protocols: FSK or CSS. The SG28 includes two dual-band SoCs with radios for both sub-GHz FSK as well as Bluetooth LE. For device makers, the SG28 dual-band parts help simplify their devices and reduce cost by including the two most used radios on Sidewalk end-devices in one package, while the SG23 provides security and a robust sub-GHz link budget for long-range, end-node devices.
