To all our customers
Regarding the change of names mentioned in the document, such as Hitachi
Electric and Hitachi XX, to Renesas Technology Corp.
The semiconductor operations of Mitsubishi Electric and Hitachi were transferred to Renesas
Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog
and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.)
Accordingly, although Hitachi, Hitachi, Ltd., Hitachi Semiconductors, and other Hitachi brand
names are mentioned in the document, these names have in fact all been changed to Renesas
Technology Corp. Thank you for your understanding. Except for our corporate trademark, logo and
corporate statement, no changes whatsoever have been made to the contents of the document, and
these changes do not constitute any alteration to the contents of the document itself.

Cautions
Keep safety first in your circuit designs!
1. Renesas Technology Corporation puts the maximum effort into making semiconductor products better
and more reliable, but there is always the possibility that trouble may occur with them. Trouble with
semiconductors may lead to personal injury, fire or property damage.
Remember to give due consideration to safety when making your circuit designs, with appropriate
measures such as (i) placement of substitutive, auxiliary circuits, (ii) use of nonflammable material or
(iii) prevention against any malfunction or mishap.

Description
These Hitachi MultiMediaCards, HB28H016MM2, HB28D032MM2, HB28B064MM2 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.
Note: MultiMediaCard is a trademark of Infineon Technologies AG.

All units in these Hitachi MultiMediaCards 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 three line MultiMediaCard interface containing the signals: CMD, CLK,
DAT (refer to Chapter “Interfaces”). For the identification of the MultiMediaCard in a stack of
MultiMediaCards, a card identification register (CID) and a relative card address register (RCA) is
foreseen. An additional register contains different types of operation parameters. This register is called
card specific data register (CSD). The communication using the MultiMediaCard lines to access either the
memory field or the registers is defined by the MultiMediaCard standard (refer to Chapter
“Communication”). The card has its own power on detection 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 MultiMediaCard system is powered up (refer to Chapter “Power Supply”). No external
programming voltage supply is required. The programming voltage is generated on card.
These Hitachi MultiMediaCards support a second interface operation mode the SPI interface mode. The
SPI mode is activated if the CS signal is asserted (negative) during the reception of the reset command
(CMD0) (refer to Chapter “SPI Communication”).
