According to SiLabs, the new EFR32MG26 Wireless SoC combines the best-in-class link budget with the leading combination of Flash, RAM and GPIO to provide the most robust and feature rich multiprotocol device for IoT end devices and ideally suited for Matter devices. “As users from consumer to industrial sectors extract more benefits from their IoT deployments, their requirements are steadily increasing,” said Matt Johnson, CEO of Silicon Labs, Inc. “The new xG26 family is built for the future, empowering device manufacturers with the confidence that their current designs will meet tomorrow’s demands”.
The high performance 2.4 GHz RF, low current consumption, AI/ML hardware accelerator and Secure Vault enables IoT device makers to create smart, robust, and energy-efficient products that are secure from remote and local cyber-attacks. A Cortex®-M33 running up to 78 MHz and up to 3200 kB of Flash and 512kB of RAM provides resources for demanding applications while leaving room for future
growth.
