Infineon Technologies SLS32AIA010MH/S/K/L OPTIGA™ Trust M

Infineon SLS32AIA010MH/S/K/L OPTIGA™ Trust M is a high-end security solution that provides an anchor of trust for connecting Internet of Things (IoT) devices to the cloud, giving every IoT device its own unique identity. This pre-personalized turnkey solution produces secured zero-touch onboarding, and the high performance needed for quick cloud access. The turnkey setup with full system integration minimizes design, integration, and deployment effort. The SLS32AIA010MK OPTIGA Trust M has a standard temperature range of -25°C to +85°C for most commercial applications. The SLS32AIA010ML has an extended temperature range of -40°C to +105°C for harsh industrial environments. The OPTIGA Trust M offers a wide range of security features, making it ideal for industrial and building automation applications, smart homes, and connected consumer devices.
