Semiconductor solutions provider STMicroelectronics has announced the launch of the ST4SIM-300, one of the first embedded SIM (eSIM) to comply with the forthcoming GSMA standard for eSIM IoT deployment, known as SGP.32. This new standard includes features designed to facilitate the management of IoT devices connected to cellular networks.
The ST4SIM-300 aims to enhance flexibility, simplify network provider switching, and ease the management of large numbers of connected devices, according to Agostino Vanore, Edge Authentication and M2M Cellular Marketing Manager at STMicroelectronics.
“Leveraging the incoming GSMA specification, our embedded SIM for IoT solution, ST4SIM-300, enhances flexibility, eases network provider switching, and simplifies managing large numbers of connected devices,” Vanore said.
Stressing its potential to track assets globally, connect smart devices to the cloud, and manage data from numerous devices, he said, “In a more connected and secured world, it will enable seamlessly track assets across the globe, connect smart devices to the cloud, and securely handle data from billions of devices, supporting our healthcare and smart infrastructures, cities, factories, and homes.”
The new eSIM standard, SGP.32, is tailored specifically for the needs of contemporary IoT deployments, unlike previous eSIM specifications for machine-to-machine (M2M) and consumer applications.
The company said that ST4SIM-300 supports automation of remote SIM provisioning (RSP), simplified management of SIM profiles for large device fleets, and remote switching between network providers, which eliminates the need for physical SIM card replacements.
Additionally, the eSIM conforms to the latest 5G standard and supports the deployment of devices with limited user interfaces and low-power wide-area network (LPWAN) capabilities.
STMicroelectronics is currently sampling the ST4SIM-300 in various form factors, including wafer-level chip-scale packages (WLCSP), making it suitable for a range of devices such as smart meters, GPS trackers, asset monitors, remote sensors, and medical wearables.
The company claimed that the ST4SIM-300 is built with an EAL6+ certified ST secure microcontroller, designed with security as a foundational element. It is compatible with the GSMA IoT SAFE applet, which facilitates the addition of secure element features for end-to-end communication.
This compatibility supports scalable security by design, benefiting creators of IoT devices by ensuring robust security measures.
