Multiband, multiprotocol IoT SoCs cover 2.4 GHz & sub-GHz bands
The multiband Wireless Gecko SoCs enable developers to use the same multiprotocol device for operation in 2.4 GHz and multiple sub-GHz bands, simplifying connected device designs. Silicon Labs has in mind application areas such as building and home automation, smart metering, security, health and fitness monitoring, connected lighting, electronic shelf labels and asset tracking.
The multiband Wireless Gecko SoCs are designed to support standards-based and proprietary 2.4 GHz protocols for short-range connectivity and proprietary sub-GHz protocols for long-range connectivity. A single hardware design can support multiple connectivity scenarios based on the firmware/software running on the SoC. This flexible architecture enables developers to work with one set of software tools while supporting proprietary stacks and standard protocols such as ZigBee, Thread and Bluetooth low energy. The Wireless Gecko SoCs also enable developers to future-proof their designs. Next-generation connected device products can embed a combination of protocols such as Bluetooth to commission and configure devices with a smartphone or tablet and sub-GHz protocols to communicate over long-range star networks.
Three SoC families span use cases and the most popular wireless protocols according to:
• Mighty Gecko family – Supports ZigBee, Thread and Bluetooth low energy connectivity at 2.4 GHz and proprietary protocols in both 2.4 GHz and sub-GHz bands
• Blue Gecko family – Supports Bluetooth low energy connectivity at 2.4 GHz and proprietary protocols in both 2.4 GHz and sub-GHz bands
• Flex Gecko family – Supports flexible proprietary wireless protocols in 2.4 GHz and sub-GHz bands for diverse applications
Silicon Labs’ Simplicity Studio development environment offers a library of software tools and access to protocol stacks to simplify connected device designs. Silicon Labs provides certified, market-proven ZigBee, Thread and Bluetooth low energy stacks for 2.4 GHz connectivity use cases, as well as new wireless software for proprietary wireless networks. Silicon Labs’ radio abstraction interface layer (RAIL) software eases the complexity of proprietary development by simplifying radio configuration and enabling developers to migrate their application code across all Wireless Gecko SoCs.
Latest wireless networking software is the Connect stack for proprietary applications. Optimized for low-power devices, this full-featured, IEEE 802.15.4-based stack supports sub-GHz and 2.4 GHz frequency bands and regulatory compliance across geographic regions. Connect software abstracts low-level details of network formation and radio configuration, enabling developers to focus on their applications. Connect provides software portability across devices and platforms, allows developers to customize stack features, and includes sample applications that give developers a starting point for their designs. The Connect stack supports point-to-point, star and extended star network topologies; many combinations of radio modulation, frequencies and data rates; all MAC layer functions such as scanning, network forming and joining; multiple devices types; and encryption and authentication of data packets.
