Description

1Description

	The ST4SIM-200S is an STMicroelectronics top-class GSMA SIM (eSIM or eUICC) product designed for IoT
	devices.
	It is compliant with the GSM Association (GSMA) remote provisioning specification SGP.02 v3.2.
	The device can manage different MNO profiles while ensuring 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, operating in the -25°C to +85 °C temperature range. This solution is a
	tamper-resistant secure element certified by Common Criteria EAL5+, with a powerful 32-bit Arm® SecurCore®
	SC300™ RISC core.

Cellular connectivity solutions overview

2Cellular connectivity solutions overview

A cellular connectivity solution enables devices to be used by the edge mobile network operators (also called MNO) or mobile virtual network operators (MVNO). This solution increases network coverage and it maintains seamless connectivity.

Moreover, a cellular solution is simple to deploy. This solution is mainly composed of the modem (baseband), the SIM card connector and the plastic SIM card. This is the traditional SIM concept inherited from the mobile phone.

Figure 1. SIM solution overview

It is also possible to have an embedded SIM (eSIM) solution. In this case, the SIM is soldered directly into the device. It reduces the board footprint and there is no need for a SIM connector.

Figure 2. eSIM solution overview

These traditional solutions are simple but the SIM / eSIM only supports one cellular connectivity profile at a time for one network operator. In this case, if the operator needs to be changed, the SIM / eSIM solution must be changed.

The eSIM GSMA solution extends this traditional SIM / eSIM solution.

ST4SIM-200S

eSIM GSMA solution

3eSIM GSMA solution

The ST4SIM-200S is a GSMA eSIM solution compliant with to Machine to Machine (M2M) specification, including IoT, industrial and automotive, defined by the GSM Association (GSMA). This solution integrates a new secure architecture and complete ecosystem able to manage cellular network connectivity remotely without impacting the eSIM component.

Thanks to this eSIM technology, IoT devices can now be deployed to the field with one network connectivity solution and if at some later stage, this solution needs to be changed, a new one can be put in place through the network. So, no need for a product recall, nor product maintenance.

This solution is flexible and does not depend on a particular operator. For M2M, including industrial and automotive markets, this solution is service-oriented; the profile is remotely controlled by the service provider through a platform (push model). In this case, end-user interaction is not required.

Figure 3. eSIM GSMA solution overview

The ST4SIM-200S is interoperable with large subscription management platforms already deployed in the field. STMicroelectronics has attended all test fest sessions driven by GlobalPlatform (including PoC on SM-SR changes initiated by GSMA) and submitted all the platform solution interfaces (ES5, ES6 and ES8 interfaces).

The device offers a complete ecosystem thanks to STMicroelectronics trusted partners. Our partners provide the connectivity profile and the subscription management platform to provision and remotely manage operator profiles. (Contact the local STMicroelectronics sales office for more details on STMicroelectronics trusted partners)

Based on a certified Common Criteria EAL5+ secure hardware solution, the ST4SIM-200S is a GSMA-certified solution compliant with the GSMA M2M specification SGP.02 v3.2. It provides a flexible and scalable solution while maintaining the best level of security.

The ST4SIM-200S integrates the GSMA architecture with the profile management mechanisms. A profile contains the operator network data related to a subscription (operator’s credentials, file system, PINs/PUKs, network authentication, application and so on). Each profile is independent of other profiles.

ST4SIM-200S

eSIM GSMA solution

The ST4SIM-200S can host up to 7 profiles. Each profile has sufficient memory size available in the device or can have a specific memory size coded using the cumulative granted memory defined by GlobalPlatform amendment C.

This profile is described by the SIMalliance interoperable profile package specification.

The ST4SIM-200S fully supports SIMalliance interoperable profile package v2.1. No proprietary features are introduced and profiles are coded according to ASN.1 / DER coding.

The ST4SIM-200S is an interoperable solution. The device already integrates most of main operators (MNO / MVNO) and it is possible to integrate any operator profile or personalized profile compliant with the SIMalliance specification.
