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 Reduced Size MultiMediaCard(RS-MMC

)s, HB28H016RM2, HB28D032RM2, and

HB28B064RM2 have same functions as MultiMediaCard

s, half size mostly, highly integrated flash

memories with serial and random access capability. These are 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 Reduced Size 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
system enables the designs of inexpensive players and drives, without moving parts. A low power
consumption and a wide supply voltage range favor mobile, battery-powered applications such as audio
players, organizers, palmtops, electronic books, encyclopedias and dictionaries. Using very effective data
compression schemes such as MPEG, the MultiMediaCard systems will deliver enough capacity for all
kinds of multimedia data: software/programs, text, music, speech, images, video and so on.

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 the 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 the 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 the 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 the chapter "SPI Communication").
