New Wireless Gecko SoC helps developers solve multi-protocol IoT design challenges

March 15, 2017 - Silicon Labs (also known as "core technology") announced a major expansion of its Wireless Gecko System-on-Chip (SoC) product line, making it easier for developers at all levels to add multi-protocol switching capabilities to Among the increasingly complex IoT applications. The new EFR32xG12 SoC supports a wide range of multi-protocol, multi-band applications for home automation, connected lighting, wearables and industrial IoT with superior RF performance, enhanced secure crypto accelerators, greater storage capacity, and on-chip Capacitive touch controllers, as well as low-power peripherals and sensor interfaces.

Bruce Bharat, director of networked control product marketing at Acuity Brands Lighting (a market leader in indoor and outdoor lighting, control and energy management solutions), said: "Multi-protocol connectivity brings more advanced features that help us simplify networked lighting control design While meeting consumer needs for easy installation and easy online updates to extend product life, Silicon Labs' Wireless Gecko platform provides us with multi-protocol SoCs, modules, robust software stacks and powerful development tools to help us. Network-controlled LED devices and control products are available quickly."

The Wireless Gecko SoC supports zigbee® and Thread mesh networks, Bluetooth® 5 and private wireless protocols. Silicon Labs optimized its wireless protocol stack architecture to enable efficient switching between different network protocols. For example, device manufacturers can now deploy and configure devices from a Bluetooth on a smartphone using a single chip and then add them to a zigbee or Thread mesh network to connect to dozens or even hundreds of endpoints.

Daniel Cooley, senior vice president and general manager of IoT products at Silicon Labs, said: "The EFR32 Wireless Gecko product line is today's most versatile and feature-rich multi-protocol platform. With new hardware and software with advanced multi-protocol connectivity, we continue Enhance the Wireless Gecko platform to meet the real-world needs of IoT products."

Excellent RF performance and safety

The Wireless Gecko family offers the highest output power (up to +19dBm) in the multi-protocol SoC market, reducing system size, cost and complexity by eliminating the external power amplifiers normally required. In addition, the EFR32xG12 SoC features excellent 2.4GHz band receive sensitivity (-102.7dBm for zigbee and Thread, -95dBm for low-power Bluetooth), and enhanced sub-GHz performance for proprietary protocol applications. . The combination of the highest RF output power and optimal receiver sensitivity provides better wireless transmission distance, higher reliability, and longer battery life for IoT applications such as smart meters.

The EFR32BG12 Blue Gecko SoC features a 2Mbps Bluetooth PHY that provides sufficient throughput for applications running the Bluetooth 5 compliant stack. The Bluetooth 5 standard supports 4x transmission distance, 2x speed, 8x broadcast performance, and enhanced coexistence with other wireless IoT protocols.

To ensure IoT security, the EFR32xG12 SoC includes a second on-chip security accelerator specifically for multi-protocol radios and NIST-certified True Random Number Generators (TRNGs). This additional hardware encryption module runs the latest security algorithms with higher performance and lower power than traditional software implementations.

More storage and peripherals

Compared to the previous generation of Wireless Gecko products, the EFR32xG12 SoC offers 4x the capacity of flash (up to 1024KB with dual-zone architecture) and 8x of RAM (up to 256KB). Storage expansion is significant, making it easier to develop complex, feature-rich IoT applications that support multi-protocol stacks, real-time operating systems (such as Micrium OS), backup firmware, and for over-the-air firmware (OTA) updates. To extend the life of IoT products.

SoC's expansion of a range of digital and analog peripherals gives developers greater design flexibility and the ability to connect additional components (such as sensors). On-chip, autonomous capacitive sensing controllers provide direct support for capacitive touch interfaces in IoT products, eliminating the cost and design complexity of typical off-chip controllers.

Price and availability

The EFR32xG12 Wireless Gecko SoC is available now in volume, sampling, and is available in a 7mm x 7mm QFN48 package and in a 65-GPIO 7mm x 7mm BGA package for feature-rich applications requiring a large number of I/O pins. The unit price of the EFR32xG12 SoC is less than $3.00 when ordered in volume. For pricing information on MightyGecko, Blue Gecko and Flex Gecko SoC, please contact your Silicon Labs sales representative or authorized distributor. The full-featured SLWSTK6000B Mighty Gecko mesh development kit supports all protocols and is priced at $499. Additional wireless daughter boards for Mighty Gecko, Blue Gecko and Flex Gecko are priced at $49. Silicon Labs' complete Simplicity Studio development tools support all of the Wireless Gecko portfolio, which is available to developers for free.
