Introduction
General Description
The SanDisk SD Card is a flash based removable non-volatile memory device specifically
designed to meet the security, capacity, performance and environmental requirements inherent
in next generation consumer electronic devices. .
The SanDisk SD Card is based on a 9-pin interface designed to operate in a maximum
operating frequency of 100 MHz. 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.
SanDisk SD cards are designed especially for use in mass storage applications. In addition to
the mass storage-specific flash memory. SD cards include 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.
