Flash Card 8G-byte 3.3V SD Card 9-Pin SD

The SD Card Product (SD Card, miniSD Card, and microSD Card) , cards are flash memory specifically designed to meet the security, capacity, performance and environmental requirements inherent in next generation mobile phones and consumer electronic devices. The SD Card Product Family includes a faster content protection system that complies with the security of the SDMI (Secure Digital Music Initiative) standard and has a higher memory capacity. The SD Card Product Family, card content is protected from illegal use by mutual authentication and a new cipher algorithm. Unsecured access to the user"s own content is also available. With some additions, the physical form factor, pin assignment, and data transfer protocol are forward compatible with future The SD Card products.Cards in The SD Card Product Family are based on a 9-pin interface designed to operate in a maximum operating frequency of 50 MHz. The SD Card specifications were originally designed by Matsushita Electric Industrial Co. Ltd., The Corporation and Toshiba Corporation (SD-3C, LLC). SD card specifications are now maintained, controlled and assigned by the SD-3C, LLC. The miniSD Card and The microSD Card are both based on the SD Card specification.The interface for SD Card products allows for easy integration into any design, regardless of which type of microprocessor is used. In addition to the interface, SD Card products offer an alternate communication-protocol based on the SPI standard. Currently, a card in The SD Card Product Family provides up to 8 GB of memory using flash memory chips, which were designed especially for use in mass storage applications. In addition to the mass storage-specific flash memory chip, cards in the SD Card Product Family includes an on-board intelligent controller which manages interface protocols; security algorithms for content protection; data storage and retrieval, as well as Error Correction Code (ECC) algorithms; defect handling; power management; wear leveling and clock control.
