Expanding its Wireless Gecko portfolio, Silicon Labs has launched its multiband, multiprotocol wireless system-on-chip (SoC) devices for the Internet of Things (IoT) market.
The new 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, reducing cost and complexity, and speeding time to market. Multiband Wireless Gecko SoCs are ideal for IoT connectivity products in application areas such as building and home automation, smart metering, security, health and fitness monitoring, connected lighting, electronic shelf labels and asset tracking.
The new multiband, multiprotocol Wireless Gecko portfolio features three SoC families optimized for IoT use cases and wireless protocols, including the Mighty Gecko line that supports ZigBee, Thread and Bluetooth low energy connectivity at 2.4 GHz and proprietary protocols in both 2.4 GHz and sub-GHz bands; the Blue Gecko line that supports Bluetooth low energy connectivity at 2.4 GHz and proprietary protocols in both 2.4 GHz and sub-GHz bands; and the Flex Gecko line that supports flexible proprietary wireless protocols in 2.4 GHz and sub-GHz bands for diverse applications.
“The IoT is a very dynamic market, with new applications, use cases, protocols and frequency band options emerging and driving explosive growth of connected device products,” said Daniel Cooley, senior vice president and general manager of IoT products at Silicon Labs. “Multiband, multiprotocol Wireless Gecko SoCs meet the needs of today’s fast-changing IoT market by giving developers the flexibility to choose the right standards-based or proprietary wireless technologies and frequency bands for their connected device designs.”
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.
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.
Silicon Labs’ 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.
It connects software abstracts low-level details of network formation and radio configuration, enabling developers to focus on their applications; and 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 reliable 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.
Samples of multiband Wireless Gecko SoCs are available in 5 mm x 5 mm QFN32 and 7 mm x 7 mm QFN48 packages; production quantities are planned for the third quarter. USD pricing in 100,000-unit quantities begins at $2.98 for multiband Mighty Gecko SoCs; $2.74 for multiband Blue Gecko SoCs; $2.70 for multiband Flex Gecko SoCs; and $2.05 for sub-GHz Flex Gecko SoCs. The SLWSTK6000A Mighty Gecko Mesh Development Kit is priced at $499. The SLWSTK6020A Blue Gecko Starter Kit is priced at $99. The SLWSTK606x Flex Gecko Wireless Starter Kits are priced at $276 each. Multiband radio boards that plug into the Wireless Gecko starter kit main boards are priced at $49 each.
