Balance Portability, Performance, and Capacity Smartphones, tablets, and cameras continue to pack more features into smaller form factors that require high storage performance. The microSD removable storage cards provide the speed necessary for demanding applications like high-resolution photography, high-definition video, and mobile gaming. The cards' high-quality NAND memory, sophisticated controller designs, and advanced memory management ensure consistent results, whether storing data at rest or capturing video at high frame rates.Up to 8GB capacity [1 gigabyte GB = 1 billion bytes. Some capacity not available for data storage.]Class 10 performanceHost-independent operationBuilt-in content protection*In-flight error checkingOverviewIndustry-Standard Design for Easy Integration into OEM ProductsThe microSD cards meet criterions with industry-standard interfaces. The interfaces for microSD cards allow for easy integration into any design, regardless of which type of microprocessor is used.SPI Standard Provides Alternative InterfaceIn addition to the standard interface, microSD cards offer an alternate communication protocol based on the SPI standard.Secure Digital Music Initiative SDMI Security for Secure Data StorageEach microSD card includes a content protection system that complies with the Secure Digital Music Initiative SDMI security standard. This system protects card content from unauthorized use through mutual authentication and a cipher algorithm, ensuring secure data storage.Intelligent Controller Provides Peak PerformanceThe on-board controller in microSD cards manages interface protocols, security algorithms, and sophisticated Error Correction Code ECC for sustained performance.
