Multi-protocol wireless SoC for the Internet of Things

[ Edited ]

Silicon Labs announced the Wireless Gecko portfolio of IoT SoC ICs for multitude of applications including connected home, lighting, building automation, wearables, metering and industrial applications.  The portfolio consist of 3 families of products aimed at the IoT.  Wireless Geckos start with the low energy architecture of the EFM32 MCU family and integrate a high performance 2.4 GHz transceiver capable of up to +19.5 dBm output power, all on a single die.  The Wireless Gecko family is supported in Simplicity Studio and has a common development platform, allowing a common set of hardware and tools to be used across the Blue Gecko, Flex Gecko and Mighty Gecko families.

Blue Gecko (EFR32BG) offers flexible price/performance options and output power scaling up to +19.5 dBm – the highest available for the Bluetooth® Smart market. In addition to the wireless SoCs, the Blue Gecko portfolio includes pre-certified wireless modules, Silicon Labs’ Bluetooth Smart software stack and an easy-to-use software development kit (SDK).

 

Flex Gecko (EFR32FG) is ideal for enabling energy-friendly proprietary protocol networking for IoT devices.  Silicon Labs Radio Abstraction Layer (RAIL) simplifies radio configuration for proprietary networks by providing a unified API across Flex Gecko products.

 

Mighty Gecko (EFR32MG) is a multi-protocol SoC capable of supporting ZigBee, Thread, BLE and proprietary networks.  With a link budget of over 120 dBm, the solution is ideal for use with Silicon Labs leading ZigBee and Thread protocol stacks. 

 

IC samples and development kits are available now starting at $99.

These are great SoCs! Do you already have information on the maximum data rate of the Flex Gecko?

@mamaupin does SiLabs plan to offer ready to use RF modules for the Mighty Gecko as well?

Kind regards,

Michael

Re: Multi-protocol wireless SoC for the Internet of Things

Is there a plan to release a version that supports sub-1Ghz radio? That would be great!

Re: Multi-protocol wireless SoC for the Internet of Things

The EZR32 series supports sub-GHz, although I have not heard any updates for them in awhile. And with LoraWAN coming out, you'd think some library updates would be in order.

Re: Multi-protocol wireless SoC for the Internet of Things

Do any of these products (or other Silabs products) bridge another protocol to WiFi? Looking for a good BLE-Wifi bridge. Would prefer to stay within the Silabs ecosystem if I can help it.

Re: Multi-protocol wireless SoC for the Internet of Things

It depends on the modulation.  For Flex Gecko, if you are using O-QPSK it is 250 kbps.  If you are using 2GFSK it is 1 Mbps.  The info is available in the Flex Gecko DS at:

Re: Multi-protocol wireless SoC for the Internet of Things

At this point, we have not announced modules based on Mighty Gecko.  We do have Bluetooth Smart Modules based on Blue Gecko (BGM111 and BGM113):

In addition, we acquired Telegesis last year and they make ZigBee Modules using or EM358x family.

Re: Multi-protocol wireless SoC for the Internet of Things

The reference manual, p. 9 states that data rates of up to 4 MBit/s can be reached by applying a symbol rate of 2 MBaud/s and a QPSK/4-FSK modulation.

Can this be confirmed? Can I access this setting in Simplicity Studio with RAIL being installed by a custom profile? There, the bitrate maxes out at 2000 kbps. Is the field "bitrate" the real bitrate or the baud rate?
