New Wireless Gecko EFR32xG12 series and new Gecko SDK Suite now available

[ Edited ]

This week Silicon Labs released additional Wireless Gecko SoCs known as the EFR32xG12 family. These devices provide larger memory options suited for applications needing multiple wireless protocols or designs wanting to use internal flash where external dataflash was previously required. Additionally, these new Wireless Gecko variants include additional or enhanced peripheral features not previously available on the EFR32xG1, such as more USARTs and Timers, Embedded Trace Macrocell (ETM) support, more GPIOs, Capacitive Touch support, and Silicon Labs' unique low-energy sensing feature (LESENSE), as well as an improved radio capable of handling Bluetooth 5 and Wireless MBus. The EFR32xG12 devices are available for order now and are included as part of the updated EFR32 Mighty Gecko Mesh Networking Kit. Ordering information and specifications can be found at the following links:



Together with these new devices we released new versions of EmberZNet and Silicon Labs Thread as part of a combined wireless suite known as Gecko Suite SDK v1.0.0.0. In addition to support for the new EFR32MG12 series, this SDK includes the following features:

  • Switched multiprotocol between Bluetooth and zigbee
  • New "Gecko Bootloader" for use with all Wireless Gecko devices across all protocol stacks, complete with AppBuilder support and enhanced security features like image signing and secure boot
  • Local Storage bootloading support for repurposing unused main flash as storage for downloaded firmware updates
  • Thread 1.1 spec updates
  • MISRA compliance across all customer-facing source code
  • Improvements to CoAP interface

Check out this new SDK by downloading or upgrading to the latest Simplicity Studio v4 and using the package manager to download the EmberZNet or Silicon Labs Thread packages.
