Description
These SD cards are highly integrated flash memories with serial and random access capability. It is accessible via a dedicated
serial interface optimized for fast and reliable data transmission. This interface allows several cards to be stacked by through
connecting their peripheral contacts. These SD cards are fully compatible to a new consumer standard, called the SD Card system
standard define in the SD card System specification. The SD card system is a new mass-storage system based on innovations in
semiconductor technology. It has been developed to provide an inexpensive, mechanically robust storage medium in card form
for multimedia consumer applications. SD card allows the design of inexpensive players and drivers without moving parts. A
low power consumption and a wide supply voltage range favors mobile, battery-powered application such as audio players,
organizers, palmtops, electronic books, encyclopedia and dictionaries. Using very effective data compression schemes such as
MPEG, the SD card will deliver enough capacity for all kinds of multimedia data.

All units these SD card are clocked by an internal clock generator. The interface driver unit synchronizes
the DAT and CMD signals from external CLK to the internal used clock signal. The card is controlled by the
six line SD card interface containing the signals: CMD,CLK,DAT0~DAT3. For the identification of the SD card
in a stack of SD card, a card identification register(CID) and a relative and address register(RCA) is foreseen.
An additional register contain different types of operation parameter. This register is called(CSD). The communication
using the SD card lines to access either the memory field or the register is defined by the SD card standard. The card
has its own power on detected unit. No additional master reset signal is required to setup the card after power on.
It is protected against short circuit during insertion and removal while the SD card system is power up. No external
programming Voltage supply is required. The programming voltage is generated on card. These SD card support
a second interface operation mode the SPI interface mode. The SPI mode is active if the CS signal is asserted(negative)
during the reception of the reset command(CMD0).
