The MicroSD and microSDHC (SD High Capacity) Cards are flash based removable non-volatile memory devices specifically designed to meet the security, capacity, performance and environmental requirements inherent in next generation mobile phones and consumer electronic devices. microSDHC cards (above 2GB) have both the SDHC and the Speed Class logo (Class 2, Class 4, Class 6 or Class 10) as defined by SD Specification Version 3.0.
The MicroSD Card includes a faster content protection system that complies with the security of the Secure Digital Music Initiative (SDMI) standard and has a higher memory capacity. In the MicroSD Card, card content is protected from illegal use by mutual authentication and a cipher algorithm. Unsecured access to the user's own content is also available.
microSD Cards are based on a 8-pin interface designed to operate in a maximum operating frequency of 50 MHz. The interface for microSD Card products allows for easy integration into any design, regardless of which type of microprocessor is used. In addition to the interface, microSD Card products offer an alternate communication protocol based on the SPI standard.
microSD Card Product Family provides up to 32 gigabytes (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 microSD 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.
