IoT Software Longevity Policy

Silicon Labs strives to provide consistent and predictable guidelines for the availability of software support for its IoT products.

The software support lifecycle described below pertains to the Silicon Labs’ Software Development Kits (SDK) and supporting tool framework. These guidelines are subject to change based on factors outside of Silicon Labs’ control, including those related to the nature of the evolving IoT landscape and its broad scope.
