Description
These Hitachi MultiMediaCard™s, HB28E016MM2, HB28D032MM2, HB28D064MM2 and
HB28B128MM2, 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 Hitachi
MultiMediaCards are fully compatible to a new consumer standard, called the MultiMediaCard system
standard defined in the MultiMediaCard system specification [1]. The MultiMediaCard 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.
MultiMediaCard allows the design of inexpensive players and drives without moving parts. A low power
consumption and a wide supply voltage range favors mobile, battery-powered applications such as audio
players, organizers, palmtops, electronic books, encyclopedia and dictionaries. Using very effective data
compression schemes such as MPEG, the MultiMediaCard will deliver enough capacity for all kinds of
multimedia data: software/programs, text, music, speech, images, video etc.

Card Specific Data (CSD)
The card specific data register describes how to access the card content. The CSD defines card operating
parameters like maximum data access time, data transfer speed.
