Product overview


The ST4SIM-110S is an STMicroelectronics SIM and embedded SIM (eSIM or eUICC) product designed for IoT devices.

The ST4SIM-110S pre-integrates a cellular connectivity configuration provided by trusted partners. In this way, the product is ready to be deployed to the field.

The device ensures the appropriate security level to all eSIM stakeholders (user, MNO, OEM, hardware integrator, service provider, and so on).

The device can include an embedded secure element to store credentials and/or independent applications directly managed by the MCU (or by another OEM element).

The device provides a secure and interoperable Java Card environment compliant with Java Card v3.0.4 classic. Moreover, the device integrates the most advanced UICC features compliant with GlobalPlatform, ETSI, 3GPP, 3GPP2 specifications.

The device integrates a dynamic memory management with Java Card garbage collection mechanism optimizing the usage of the memory.

The device is based on the ST33G1M2, an industrial grade hardware solution (JEDEC) supporting severe conditions. This solution is a tamper-resistant secure element certified by Common Criteria EAL5+, with a powerful 32-bit Arm SecurCore SC300 RISC core.
