The ST4SIM-300M is a STMicroelectronics top-class GSMA embedded SIM (eSIM or eUICC) product designed for all IoT devices.
It is compliant with the GSM Association (GSMA) specification SGP.32 v1.2.
The ST4SIM-300M can remotely manage profiles of different MNOs while ensuring the appropriate security level to all eUICC 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 v. 3.0.5 Classic. Moreover, the device integrates the most advanced UICC features compliant with GlobalPlatform®, ETSI and 3GPP specifications.
The ST4SIM-300M integrates a dynamic memory management with Java® Card garbage collection mechanism optimizing the usage of the memory.
The ST4SIM-300M is based on the ST33K1M5M, an industrial grade hardware solution (JEDEC) supporting severe conditions. This solution is a tamper-resistant secure element certified by Common Criteria EAL6+, with a powerful 32-bit Arm® Cortex®-M35P CPU.
