Multiprotocol multi-band IoT connectivity in a 7x7mm SoC

March 14, 2017 // By Julien Happich
Silicon Labs announced a major expansion of its Wireless Gecko system-on-chip (SoC) portfolio, supporting versatile multiprotocol switching capabilities across multiband use cases with its EFR32xG12 SoCs.

Wireless Gecko SoCs support zigbee and Thread mesh networking, Bluetooth 5 and proprietary wireless protocols. Silicon Labs has optimized its wireless protocol stack architecture to enable efficient switching between different network protocols. For example, device makers can now use a single chip to commission and configure devices over Bluetooth with a smartphone, and then join a zigbee or Thread mesh network to connect to dozens or even hundreds of end nodes.

The chip delivers up to +19dBm of output power and eliminates the need for an external power amplifier. EFR32xG12 SoCs also offer exceptional sensitivity in the 2.4 GHz band (-102.7 dBm for zigbee and Thread and -95 dBm for Bluetooth low energy) as well as improved sub-GHz performance for applications using proprietary protocols. The chips feature a 2 Mbps Bluetooth PHY, providing ample throughput for applications running a Bluetooth 5-compliant stack. The Bluetooth 5 standard enables four times the range, twice the speed, 800 percent greater broadcasting capacity and improved co-existence with other wireless IoT protocols.
