Delkin Devices 128GB Utility Industrial microSD
Overview
The S41HFQYFA-U1000-3 is a 128GB 3D NAND microSD memory card designed for reliable data storage in demanding environments. It features a robust industrial-grade controller that manages sophisticated wear leveling and bad block management to extend the lifespan of the flash memory. Operating between 2.7V and 3.6V, it is optimized for consistent performance in OEM applications where data integrity is critical.
Why Choose This Part
This card provides built-in SMART data reporting and a dashboard for predictive maintenance, allowing engineers to monitor the health of the flash storage. It incorporates Auto-Read Refresh and Error Correction Code (ECC) to prevent data corruption, while maintaining a typical operating current of less than 400 mA for both read and write cycles.
Applications
Key Specifications
Getting Started
The card supports both standard SD and SPI interfaces, making it compatible with a wide range of microcontrollers and single-board computers. For SPI-based systems, ensure the host controller is configured for 3.3V logic and implement a standard FAT32 or exFAT file system driver. Developers can use the Delkin SMART dashboard to assess remaining life during system prototyping and qualification.
