Multiprotocol wireless IoT device series launched

10 April 2024

Silicon Labs has introduced a series of wireless system-on-chips (SoCs) and microprocessors designed for internet of things (IoT) devices that support multiple protocols like Matter, Zigbee, OpenThread, Bluetooth Low Energy and Bluetooth Mesh.

The three-device series are designed to work for demanding applications today and emerging applications in the future with double the flash and RAM compared to other Silicon Labs multiprotocol devices.

The double flash, RAM and general-purpose input/output (GPIO) pin capacity allows engineers to create devices that connect to twice as many peripherals for better system integration, Silicon Labs said.

Additional features of the devices include:

  • Multicore ARM Cortex-M33 CPU and dedicated cores
  • Embedded artificial intelligence and machine learning hardware acceleration
  • Silicon Labs Secure Vault
  • Arm TrustZone
  • 2.4 GHz wireless connectivity

Silicon Labs said it has designed these series to be prepared for the next generation of Matter devices as they come available. Most device types have already seen Matter’s code requirements grow by 6% in the first 18 months since its inception in October of 2022.

Matter is a type of communication in smart devices that allow multi-brand support under one control. So regardless if a smart home device is from Amazon, Google, Apple, Samsung, Nanoleaf and more, all will work under the same communication app or hub. This is a big step from having to need numerous apps for every device that is not from the same manufacturer.

The SoCs in this new series are designed so that when consumers buy a Matter device this year, the new Matter-enabled device they replace it with next year will continue to work, the company said.
