Product details
Overview
ST4SI2M0020TPIFW from STMicroelectronics is a GSMA SGP.02 v3.2–compliant embedded SIM (eUICC) with integrated secure element, built on the ST33G1M2M industrial-grade hardware platform featuring a 32-bit Arm® SecurCore® SC300™ RISC core, EAL5+ Common Criteria certification, and support for up to 7 remote operator profiles across LTE Cat-M1, NB-IoT, 2G/3G/4G, and CDMA networks.
For engineers reviewing the ST4SI2M0020TPIFW datasheet, ST4SI2M0020TPIFW pinout, ST4SI2M0020TPIFW application, or ST4SI2M0020TPIFW equivalent, this device delivers certified interoperability with GlobalPlatform® v2.2, Java Card v3.0.4 Classic, OTA management via HTTPS/TLS 1.0–1.2 and CAT-TP, and dual-interface operation (ISO/IEC 7816 + SPI) in VFDFPN8 and WLCSP11 packages for industrial M2M deployments requiring tamper-resistant credential storage and dynamic profile switching.
Technical Context
The ST4SI2M0020TPIFW implements a dual-domain architecture: the eSIM domain handles GSMA-compliant remote provisioning (SGP.02), profile lifecycle management, and UICC applications (USIM/ISIM/CSIM), while the optional eSE domain provides Java Card–based cryptographic services via SPI-enabled only in WLCSP11 and VFDFPN8 packages supporting both protocols. It uses a dedicated ratification counter and DPA/SPA countermeasures to harden MILENAGE/TUAK/CAVE authentication.
Its memory subsystem features dynamic garbage-collected Java Card heap, GlobalPlatform Amendment C–based cumulative granted memory allocation, and Flash wear-leveling optimized for frequent OTA updates. The device operates across –40°C to +105°C, qualified per JEDEC JESD47, and supports power-saving modes (PSM/eDRX) per ETSI Release 13.
Key Specifications

Pinout & Package
ST4SI2M0020TPIFW is offered in VFDFPN8 (5 × 6 mm, wettable flanks, MFF2-compliant) and WLCSP11 packages. The VFDFPN8 variant supports dual-interface operation (ISO/IEC 7816 + SPI) and is qualified for automated optical inspection of solder joints due to its dimpled wettable flank design.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power supply input | Accepts Class A/B/C voltages (1.8 V / 3 V / 5 V); requires 100 nF + 1 µF decoupling per datasheet Figure 6 |
| RESET | Active-low reset input | Pull-down by default; initiates cold/warm reset sequence compliant with ISO/IEC 7816-3 T=0 timing |
| CLK | Clock input | Pull-down during reset; accepts external clock source per ETSI TS 102 671 timing constraints |
| GND | Ground reference | Primary return path for VCC and I/O; must be low-impedance connection to minimize noise coupling |
| SWIO | Single-wire I/O (not used) | Internally unused; left unconnected - no pull-up/down required |
| I/O | ISO/IEC 7816 bidirectional data | Pull-down at power-on, transitions to pull-up after activation; supports T=0 protocol only |
| NC | No connect | Two pins (4 and 8) are internally unconnected; must remain floating per mechanical layout |
Key Features
| Feature | Design Value |
|---|---|
| Dual-interface architecture | eSIM domain (ISO/IEC 7816) and eSE domain (SPI) operate concurrently - enables independent modem control and secure applet execution |
| Dynamic memory management | Java Card garbage collection + Flash wear-leveling - ensures >100k OTA update cycles without memory fragmentation |
| MFF2-compliant packaging | VFDFPN8 meets ETSI TS 102 671 machine-to-machine form factor - enables direct PCB soldering without SIM connector or tray |
| Industrial temperature resilience | Validated operation from –40°C to +105°C per JEDEC JESD47 - suitable for outdoor metering and automotive telematics housings |
| OTA DNS integration | Built-in DNS client resolves HTTPS server addresses during profile download - eliminates need for hardcoded IP in firmware |
Applications
| Smart Gas Metering | Industrial Asset Tracking |
|---|---|
|
Use Scenario: Battery-powered ultrasonic gas meters deployed in unconditioned utility cabinets across wide geographic regions. IC Role / Device Role / Timing Role: eUICC managing remote carrier profile swaps during regional network migration, with TLS-secured OTA updates over NB-IoT. Use Value: Eliminates field replacement of physical SIMs when switching MVNOs, reducing OPEX by >70% per deployment cycle. |
Use Scenario: Ruggedized GPS trackers mounted on shipping containers operating across multiple cellular bands and jurisdictions. IC Role / Device Role / Timing Role: Secure element hosting carrier-agnostic profile management logic and cryptographic keys for IMSI masking and location reporting. Use Value: Enables single-hardware SKU for global logistics - profiles updated remotely as containers cross borders without manual intervention. |
| Smart City Surveillance | Connected Factory Sensors |
|
Use Scenario: Outdoor IP cameras powered by solar/battery hybrid systems transmitting video metadata over LTE Cat-M1. IC Role / Device Role / Timing Role: eSIM providing authenticated, encrypted connectivity to municipal cloud platforms using MILENAGE-based network access. Use Value: Prevents unauthorized camera hijacking via hardware-enforced key isolation and runtime attestation of firmware integrity. |
Use Scenario: Predictive maintenance sensors embedded in CNC machinery requiring zero-touch provisioning in sealed industrial enclosures. IC Role / Device Role / Timing Role: Dual-interface operation allows MCU to manage eSIM profiles via ISO/IEC 7816 while offloading crypto operations to eSE via SPI. Use Value: Reduces MCU firmware complexity by delegating TLS handshake and certificate validation to the secure element. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar eUICC and secure element applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon SLB9670 | Supports only single-profile eSIM; lacks GSMA SGP.02 v3.2 compliance and GlobalPlatform v2.2 amendment support | Targeted at legacy M2M deployments where profile switching is not required | Select if cost-sensitive designs need basic secure boot and TPM-like functionality without remote provisioning |
| NXP JCOP4 SE050 | Standalone secure element only - no integrated eSIM functionality or UICC OS; requires external eSIM controller | Suitable for architectures where eSIM and eSE are physically separated for redundancy or certification boundaries | Choose when system-level security mandates separation of provisioning logic (host MCU) and cryptographic key storage (SE) |
Compared with SLB9670 and JCOP4 SE050, ST4SI2M0020TPIFW uniquely integrates certified GSMA-compliant remote provisioning, multi-profile management, and dual-interface secure execution in a single industrial-grade package - eliminating inter-chip communication latency and reducing BOM count by one component.

FAQ
What is the maximum number of operator profiles supported by ST4SI2M0020TPIFW?
The device supports up to 7 operator profiles, with memory allocation governed by GlobalPlatform Amendment C's cumulative granted memory mechanism. Actual capacity depends on profile size and configuration; typical deployments use 3–5 active profiles with guaranteed space for future OTA additions. Memory defragmentation occurs automatically during profile installation or deletion.
Does ST4SI2M0020TPIFW support both eSIM and eSE functions simultaneously?
Yes - the device implements concurrent eSIM (ISO/IEC 7816 interface) and eSE (SPI interface) domains. This requires the VFDFPN8 or WLCSP11 package variants, which expose both interfaces. The eSE section hosts Java Card applets for cryptographic services, while the eSIM domain manages profile lifecycle and network authentication independently.
Is ST4SI2M0020TPIFW compatible with standard SIM card sockets?
No - ST4SI2M0020TPIFW is not supplied in plug-in card formats for socket insertion. It is offered exclusively in surface-mount packages (VFDFPN8 and WLCSP11) designed for direct PCB soldering. The "2FF/3FF/4FF" reference in documentation describes the underlying D16 micromodule's compatibility with card form factors - not this specific part number.
What TLS versions does the ST4SI2M0020TPIFW support for HTTPS-based OTA updates?
The device supports TLS v1.0, v1.1, and v1.2 for HTTPS-based remote management, as verified in GlobalPlatform-certified "Muse eUICC-i2 v1" test reports. It does not support TLS v1.3. Certificate validation follows X.509 v3 standards, and private key operations occur entirely within the secure element - never exposed to the host MCU.
