Memory IC Procurement Notes

Verify the exact part number against official Swissbit documentation, as suffixes may indicate specific revisions or configurations not explicitly detailed in general summaries. Confirm availability status, as industrial components often undergo lifecycle changes. Ensure compatibility with host controller voltage requirements (1.8V or 3.3V VCCQ) before integration. Check for any recent Product Change Notifications (PCN) that might affect form, fit, or function.

Memory IC Selection Notes

Select this component for applications requiring robust industrial temperature ranges (-40°C to +85°C) and high reliability. The MLC configuration offers a balance between performance and endurance suitable for moderate write-intensive tasks. Consider the enhanced/reliable mode for intensive write applications to maximize lifespan. Ensure the host system supports eMMC 5.0 specifications and HS400 High Speed Mode if maximum throughput is required.

Memory IC Part Context

This part belongs to the Swissbit EM-20 series of industrial eMMC memories, designed for long life cycles and superior data retention. The series utilizes sophisticated firmware architecture tailored for industrial and embedded markets. It emphasizes controlled Bill of Materials (BOM) and Process Change Notification (PCN) processes to ensure supply chain stability and product consistency over extended periods.

Memory IC Replacement Considerations

Direct replacements within the same series include other densities such as SFEM4096B1EA1TO-I-GE-111-STD (4GB), SFEM016GB1EA1TO-I-GE-111-STD (16GB), SFEM032GB1EA1TO-I-LF-111-STD (32GB), and SFEM064GB1EA1TO-I-HG-111-STD (64GB). These share identical physical dimensions, pinouts, and interface specifications, differing only in storage capacity and potentially specific thermal or endurance characteristics defined by their respective suffixes.
