Application Specific Microcontrollers Procurement Notes

Verify the specific package variant required, as the product is available in 2FF, 3FF, or 4FF plugin card formats based on D16 micromodule, as well as DFN8 with wettable flanks (MFF2) and WLCSP11. Confirm supply chain compliance with ECCN classifications (US: 3A991.a.2; EU: NEC) prior to ordering. Ensure the selected form factor matches the target device's physical interface constraints.

Application Specific Microcontrollers Selection Notes

Select the appropriate voltage class based on the host system: Class A (5 V), Class B (3 V), or Class C (1.8 V). The device supports asynchronous serial I/O compatible with ISO/IEC 7816-3 (T=0 protocol) and SPI interfaces depending on the package. Verify that the application requires the specific pre-integrated connectivity configuration provided by trusted partners, as this is a key differentiator of the ST4SIM-110M architecture.

Application Specific Microcontrollers Part Context

This component is part of the ST4SIM-110M product line from STMicroelectronics. It is built upon the ST33G1M2M hardware foundation, which utilizes the Arm SecurCore SC300 processor. The series is specifically engineered for industrial-grade environments, offering robust security features and wide operating temperature ranges suitable for demanding M2M deployments.

Application Specific Microcontrollers Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. The ST4SIM-110M designation refers to the specific product family integrating the connectivity configuration. Any replacement must match the exact package type (e.g., MFF2, 2FF, 3FF, 4FF) and voltage class requirements.
