• Supports configurable multiple partitions via standard e.MMC register access for flexible data management.
• Includes automatic background data refresh for read-only areas to ensure long-term data retention under high temperatures.
• Provides enhanced protection against data corruption during sudden power loss events.
• Offers visibility into device health metrics, such as write cycles and internal resource status.

Memory IC Applications

• Automotive infotainment systems
• Advanced Driver Assistance Systems (ADAS)
• Industrial programmable logic controllers (PLCs)
• Medical system data logging

Memory IC Procurement Notes

Verify the specific suffix VG-121-STD against official Swissbit documentation to confirm exact configuration details. Ensure compatibility with host interfaces supporting e.MMC 5.1 standards. Confirm that the 153-ball BGA footprint matches the target PCB design constraints. Validate that the operating environment remains within the specified -40°C to +105°C thermal limits for reliable performance.

Memory IC Selection Notes

Select this component when high-density storage is required in space-constrained embedded applications. The EM-30 series is suitable for environments demanding robust data integrity and wide temperature tolerance. Consider the 3D TLC technology for cost-effective high-capacity solutions where pSLC mode is not strictly necessary. Ensure the host controller supports the required voltage levels and interface speeds for optimal throughput.

Memory IC Part Context

This part belongs to the Swissbit EM-30 series, designed for industrial and automotive embedded storage needs. It utilizes advanced 3D-NAND TLC technology to deliver high capacities in a small form factor. The series emphasizes reliability through features like read interference management and power-loss protection. It serves as a solid-state alternative to traditional mechanical drives in rugged electronic systems.

Memory IC Replacement Considerations

Direct substitutes within the same family include other EM-30 variants with different capacities or suffixes, such as SFEM128GB2ED1TB-A-EF-111-STD. Verify pinout compatibility and firmware differences before substitution. Cross-referencing with the EM-36 series may be considered if pre-configured pSLC mode is preferred over configurable partitions.
