Smartphones, tablets, and cameras continue to pack more features into smaller form factors that require high storage performance. SanDisk 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.
SanDisk provides a broad product portfolio of microSD cards with industry-standard interfaces. The interfaces for microSD cards allow for easy integration into any design, regardless of which type of microprocessor is used.
In addition to the standard interface, microSD cards offer an alternate communication protocol based on the SPI standard.
Each SanDisk 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.
The on-board controller in SanDisk microSD cards manages interface protocols, security algorithms, and sophisticated Error Correction Code (ECC) for sustained performance.
Thanks to SanDisk microSD cards' intelligent onboard controllers, systems that support microSD cards today will be compatible with future SanDisk cards. As flash technology evolves, OEMs won't have to update or change host software.
SanDisk controls every step of the NAND flash manufacturing process, as well as product architecture, controller design, and supply chain, ensuring OEMs get the quality and flexibility they need to compete effectively.
