HB288064MM1
MultiMediaCard™
64 MByte
ADE-203-1191 (Z)
Preliminary
Rev. 0.0
Jul. 25, 2000
Description
The Hitachi MultiMediaCard™ HB288064MM1 is a highly integrated flash memory 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. The HB288064MM1 is 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 Siemens AG.
Features
• 64 MByte memory capacity
• On card error correction

Registers
The HB288064MM1 contains the following information registers:
Name
OCR
CID
RCA
CSD
Width
32
128
16

Type
Programmed by the
manufacturer.
Read only for user
Programmed by the
manufacturer.
Read only for user
Programmed during
initialization, not readable
Programmed by the
manufacturer. Partially
programmable by the user.
Description
Supported voltage range, card power up status bit
Card identification number, card individual number for
identification.
Relative card address, local system address of a card,
dynamically assigned by the host during initialization.
Card specific data, information about the card operation
conditions.
CID and RCA are used for identifying and addressing the HB288064MM1. The third register contains the
card specific data record. This record is a set of information fields to define the operation conditions of the
HB288064MM1.
For the user the CID and the CSD are read only registers. They are read out by special commands (refer to
Chapter “Commands”). The RCA registers are write only registers. Unlike CID and CSD, RCA looses its
contents after powering down the card. Its value is reassigned in each initialization cycle. The
MultiMediaCard registers usage in SPI mode is summarized in Table “MultiMediaCard Registers in SPI
Mode”:

HB288064MM1
• VDD_R_CURR_MIN, VDD_W_CURR_MIN
The maximum supply current at the minimum supply voltage VCC (2.7 V) is coded as follows:
Maximum Supply Current Consumption at VCC = 2.7 V
VDD_R_CURR_MIN
VDD_W_CURR_MIN
2:0
Code for current consumption at 2.7 V
0 = 0.5 mA; 1 = 1 mA; 2 = 5 mA; 3 = 10 mA; 4 = 25 mA; 5 = 35 mA; 6
= 60 mA; 7 = 100 mA
The parameter VDD_R_CURR_MIN and VDD_W_CURR_MIN are permanently assigned to the value 5
(35 mA).
• VDD_R_CURR_MAX, VDD_W_CURR_MAX
The maximum supply current at the maximum supply voltage VCC (3.6 V) is coded as follows:
Maximum Supply Current Consumption at VCC = 3.6 V
VDD_R_CURR_MAX
VDD_W_CURR_MAX
2:0
Code for current consumption at 3.6 V
0 = 1 mA; 1 = 5 mA; 2 = 10 mA; 3 = 25 mA; 4 = 35 mA; 5 = 45 mA; 6 =
80 mA; 7 = 200 mA
The parameter VDD_R_CURR_MAX and VDD_W_CURR_MAX are permanently assigned to the value 5
(45 mA). For more details refer to Chapter “Characteristics”.
