Description
These Renesas MultiMediaCards, HB28K032MM3, HB28K032RM3, HB28L064MM3,
HB28L064RM3, HB28J128MM3, HB28J128RM3, HB28J256MM3, HB28J256RM3 and HB28J512MM3
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 Renesas 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 favor 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.

All units in these Renesas 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) are
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 Renesas 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”).

Interface
These Renesas MultiMediaCards' interface can operate in two different modes:
• MultiMediaCard mode
• SPI mode
Both modes are using the same pins. The default mode is the MultiMediaCard mode. The SPI mode is
selected by activating (= 0) the CS signal (Pin1) and sending the CMD0.
MultiMediaCard Mode
In the MultiMediaCard mode, all data is transferred over a minimal number of lines:
• CLK: with each cycle of this signal a one-bit transfer on the command and data lines is done. The
frequency may vary between zero and the maximum clock frequency. The MultiMediaCard bus
master is free to generate these cycles without restrictions in the range of 0 to 20 MHz.
• CMD: is a bidirectional command channel used for card initialization and data transfer commands.
The CMD signal has two operation modes: open drain for initialization mode and push pull for fast
command transfer. Commands are sent from the MultiMediaCard bus master to the MultiMediaCard
and responses vice versa.
• DAT: is a bidirectional data channel with a width of one line. The DAT signal of the MultiMediaCard
operates in push pull mode.
Interface driver
• RSV: is pulled up with resistor (2 MΩ typ) in the MultiMediaCard. The external pull-up resistor
should be recommended if the system requires.

SPI Mode
The Serial Peripheral Interface (SPI) is a general-purpose synchronous serial interface originally found on
certain Motorola microcontrollers. The MultiMediaCard SPI interface is compatible with SPI hosts
available on the market. As any other SPI device the MultiMediaCard SPI interface consists of the
following four signals:
CS: Host to card Chip Select signal.
CLK: Host to card clock signal.
Data in: Host to card data signal.
Data out: Card to host data signal.
The MultiMediaCard card identification and addressing methods are replaced by a hardware Chip Select
(CS) signal. There are no broadcast commands. For every command, a card (slave) is selected by
asserting (active low) the CS signal (refer to Figure “SPI Bus System”). The CS signal must be
continuously active for the duration of the SPI transaction (command, response and data). The only
exception occurs during card programming, when the host can de-assert the CS signal without affecting the
programming process. The bidirectional CMD and DAT lines are replaced by unidirectional data in and
data out signals. This eliminates the ability of executing commands while data is being read or written and,
therefore, makes the sequential and multi block read/write operations obsolete. The single and multiple
block read/write commands are supported by the SPI channel. The SPI interface uses the same seven
signals of the standard MultiMediaCard bus (refer to Table “SPI Interface Pin Configuration”).

MultiMediaCard.
For the user, the CID is read only register. The CSD contains read only area and some of one time or
multiple programmable area by the customer or provider. 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

The CID has to be error free. To ensure the correctness of the CID, a 7-bit CRC checksum is added to the
end of the CID. The CRC7 is computed according to chapter “Cyclic Redundancy Check (CRC)”.
Relative Card Address (RCA)
The 16-bit relative card address register carries the card address assigned by the host during the card
identification. This address is used for the addressed host to card communication after the card
identification procedure. The default value of the RCA register is 0x0001. The value 0x0000 is reserved
to set all cards in Standby State with the command SELECT_DESELECT_CARD (CMD7). The RCA is
programmed with the command SET_RELATIVE_ADDRESS (CMD3) during the initialization procedure.
The content of this register is lost after power down. The default value is assigned when an internal reset is
applied by the power up detection unit of these Renesas MultiMediaCards, or when the command
GO_IDLE_STATE (CMD0) is detected by these Renesas MultiMediaCards.

The value for the asynchronous delay for these Renesas MultiMediaCards is 1 ms. The coded TAAC value
is 0x0E (= 1 ms). For more details refer to Chapter “Operating Characteristics”.
• NSAC
Defines the worst case for the synchronous data access time. The unit for NSAC is 100-clock cycles.
Therefore, maximum value for the data access time is 25.6k clock cycles. The total access time NAC as
expressed in the Table “Timing Values” is the sum of both TAAC and NSAC. It has to be computed by
the host for the actual clock rate. The read access time should be interpreted as a typical delay for the first
data bit of a data block or stream. The value of NSAC for these Renesas MultiMediaCards is 0x01 (100clock cycles). For more details refer to Chapter “Operating Characteristics”.

The block length might therefore be in the range 1, 2, 4...2048 bytes. This parameter defines the block
length if READ_BLK_PARTIAL is not set. If READ_BLK_PARTIAL is set this parameter contains the
maximum allowed value of the block length in bytes. All block lengths between one and this value are
permitted. The actual block size is programmed by the command SET_BLOCKLEN (CMD16). These
Renesas MultiMediaCards support block lengths from 1 byte up to 2048 bytes. The default value of the
parameter READ_BLK_LEN is 0x9 (512 bytes).
• READ_BLK_PARTIAL
READ_BLK_PARTIAL defines whether partial block sizes can be used in block read command.
READ_BLK_PARTIAL = 0 means that only the block size defined by READ_BLK_LEN can be used for
block-oriented data transfers. READ_BLK_PARTIAL = 1 means that smaller blocks can be used as well.
The minimum block size will be equal to minimum addressable unit (one byte). These Renesas
MultiMediaCards support partial block read. The parameter READ_BLK_PARTIAL is permanently
assigned to the value ‘1’.
• WRITE_BLK_MISALIGN
Defines if the data block to be written by one command can be spread over more than one physical blocks
of the memory device. The size of the memory block is defined in WRITE_BLK_LEN.
WRITE_BLK_MISALIGN is permanently assigned to the value ‘0’, signaling that crossing physical block
boundaries is not allowed.
• READ_BLK_MISALIGN
Defines if the data block to be read by one command can be spread over more than one physical block of
the memory device. The size of the data block is defined in READ_BLK_LEN.
READ_BLK_MISALIGN = 0 signals that crossing physical block boundaries is not allowed.
READ_BLK_MISALIGN = 1 signals that crossing physical block boundaries is allowed. These Renesas
MultiMediaCards do not support read block operations with boundary crossing. The parameter
READ_BLK_MISALIGN is permanently assigned to the value ‘0’.

• ERASE_GRP_SIZE
The content of this register is a 5 bit binary coded value, used to calculate the size of the erasable unit of
these Renesas MultiMediaCards. The size of the erase unit (also referred to as erase group in chapter
“Memory Array Partitioning”) is determined by the ERASE_GRP_SIZE and the ERASE_GRP_MULT
entries of the CSD, using the following equation:
size of erasable unit = (ERASE_GRP_SIZE + 1) * (ERASE_GRP_MULT + 1)
The parameter ERASE_GRP_SIZE is permanently assigned to the value ‘0’. The size of erasable unit for
these Renesas MultiMediaCards is (0+1) * (15+1) = 16, which means that the 8 KByte area can be erased
in a single erase group command (CMD35, CMD36 and CMD38).

MultiMediaCard Communication
All communication between host and cards is controlled by the host (master). The host sends commands
and, depending on the command, receives a corresponding response from the selected card. In this chapter
the commands to control these Renesas MultiMediaCards, the card responses and the contents of the status
and error field included in the responses, are defined.
Memory Array Partitioning
The basic unit of data transfer to/from the MultiMediaCard is one byte. All data transfer operations which
require a block size always define block lengths as integer multiples of bytes. Some special functions need
other partition granularity. For block-oriented commands, the following definition is used:
• Block: is the unit which is related to the block-oriented read and write commands. Its size is the
number of bytes which will be transferred when one block command is sent by the host. The size of a
block is either programmable or fixed. The information about allowed block sizes and the
programmability is stored in the CSD.
For devices which have erasable memory cells, special erase commands are defined. The granularity of the
erasable units is:
• Sector: In these Renesas MultiMediaCards, this size is same as the WRITE_BLK_LEN in CSD.
• Erase Group: is the smallest number of consecutive write blocks, which can be addressed for erased.
The size of the Erase Group is card specific and stored in the CSD.
For devices which include a write protection:
• WP-Group: is the minimal unit which may have individual write protection. Its size is the number of
erase groups which will be write protected by one bit. The size of a WP-group is fixed for each
device. The information about the size is stored in the CSD.
Each erasable unit (erase group) has a special “tag” bit. This bit may be set or cleared by special
commands to tag the unit. All tagged units will be erased in parallel by one erase command following a
number of tag commands. All tag bits are cleared by each command except a tag command. Therefore,
immediately after a sequence of tag commands an erase command has to be sent by the host. Commands
others than tagging or erasing abort a tag-erase cycle irregularly.

Class 0 is mandatory and supported by all cards. It represents the card identification and initialization
commands, which are intended to handle different cards and card types on the same bus lines. The Card
Command Class (CCC) is coded in the card specific data register of each card, so that the host knows how
to access the card. There are four kinds of commands defined on the MultiMediaCard bus:
• broadcast commands (bc) sent on CMD line, no response
• broadcast commands with response (bcr) sent on CMD line, response (all cards simultaneously) on
CMD line
• addressed (point-to-point) commands (ac) sent on CMD line, response on CMD line
• addressed (point-to-point) data transfer commands (adtc) sent on CMD line, response on CMD line,
data transfer on DAT line

The command transmission always starts with the MSB. Each command starts with a start bit and ends
with a 7-bit CRC command protection field followed by an end bit. The length of each command frame is
fixed to 48 bits (2.4 µs at 20 MHz):

Note: 1. (Cyclic Redundancy Check)
The start bit is always ‘0’ in command frames (sent from host to MultiMediaCard). The host bit is always
‘1’ for commands. The command field contains the binary coded command number. The argument
depends on the command (refer to Table “Basic Commands (class 0) and Table “Block-Oriented Read
Commands (class 2)”). The CRC field is defined in Chapter “Cyclic Redundancy Check (CRC)”.

Read, Write and Erase Time-out Conditions
The times after which a time-out condition for read/write/erase operations occurs are (card independent) 10
times longer than the access/program times for these operations given below. A card shall complete the
command within this time period, or give up and return an error message. If the host does not get a
response within the defined time-out it should assume the card is not going to respond anymore and try to
recover (e.g. reset the card, power cycle, reject, etc.). The typical access and program times are defined as
follows:
Read
The read access time is defined as the sum of the two times given by the CSD parameters TAAC and
NSAC (refer to Table “Card Specific Data (CSD)”). These card parameters define the typical delay
between the end bit of the read command and the start bit of the data block. This number is card dependent
and should be used by the host to calculate throughput and the maximal frequency for stream read.
Write
The R2W_FACTOR field in the CSD is used to calculate the typical block program time obtained by
multiplying the read access time by this factor. It applies to all write/erase commands (e.g.
SET(CLEAR)_WRITE_PROTECT, PROGRAM_CSD(CID) and the block write commands). It should be
used by the host to calculate throughput and the maximal frequency for stream write.
Erase
The duration of an erase command will be (order of magnitude) the number of write blocks to be erased
multiplied by the block write delay.

MultiMediaCard State Diagram (Card Identification Mode)
The host starts the card identification process in open drain mode with the identification clock rate fOD
(generated by a push pull driver stage). The open drain driver stages on the CMD line allow the parallel
card operation during card identification. After the bus is activated the host will request the cards to send
their valid operation conditions with the command SEND_OP_COND (CMD1). Since the bus is in open
drain mode, as long as there is more than one card with operating conditions restrictions, the host gets in
the response to the CMD1 a “wired or” operation condition restrictions of those cards. The host then must
pick a common denominator for operation and notify the application that cards with out of range
parameters (from the host perspective) are connected to the bus. Incompatible cards go into Inactive State
(refer to also Chapter “Operating Voltage Range Validation”). The busy bit in the CMD1 response can be
used by a card to tell the host that it is still working on its power-up/reset procedure (e.g. downloading the
register information from memory field) and is not ready yet for communication. In this case the host must
repeat CMD1 until the busy bit is cleared. After an operating mode is established, the host asks all cards
for their unique card identification (CID) number with the broadcast command ALL_SEND_CID (CMD2).
All not already identified cards (i.e. those which are in Ready State) simultaneously start sending their CID
numbers serially, while bit-wise monitoring their outgoing bitstream. Those cards, whose outgoing CID
bits do not match the corresponding bits on the command line in any one of the bit periods, stop sending
Rev.0.02, Sep.15.2004, page 33 of 89
HB28K032/L064/J128/J256/J512MM3, HB28K032/L064/J128/J256RM3
their CID immediately and must wait for the next identification cycle (cards stay in the Ready State).
There should be only one card which successfully sends its full CID-number to the host. This card then
goes into the Identification State. The host assigns to this card (using CMD3, SET_RELATIVE_ADDR) a
relative card address (RCA, shorter than CID), which will be used to address the card in future
communication (faster than with the CID). Once the RCA is received the card transfers to the Standby
State and does not react to further identification cycles. The card also switches the output drivers from the
open-drain to the push-pull mode in this state. The host repeats the identification process as long as it
receives a response (CID) to its identification command (CMD2). When no card responds to this
command, all cards have been identified. The time-out condition to recognize this, is waiting for the start
bit for more than 5 clock periods after sending CMD2.
Operating Voltage Range Validation
The MultiMediaCard standards operating range validation is intended to support reduced voltage range
MultiMediaCards. These Renesas MultiMediaCards support the range of 2.7 V to 3.6 V supply voltage.
So these Renesas MultiMediaCards send a R3 response to CMD1 which contains an OCR value of
0x80FF8000 if the busy flag is set to “ready” or 0x00FF8000 if the busy flag is active (refer to Chapter
“Responses”). By omitting the voltage range in the command, the host can query the card stack and
determine the common voltage range before sending out-of-range cards into the Inactive State. This bus
query should be used if the host is able to select a common voltage range or if a notification to the
application of non usable cards in the stack is desired. Afterwards, the host must choose a voltage for
operation and reissue CMD1 with this condition, sending incompatible cards into the Inactive State.

Data Transfer Mode
When in Standby State, both CMD and DAT lines are in the push-pull mode. As long as the content of all
CSD registers is not known, the fPP clock rate is equal to the slow fOD clock rate. SEND_CSD (CMD9)

capacity, maximum clock rate etc.

MultiMediaCard State Diagram (Data Transfer Mode)
The command SELECT_DESELECT_CARD (CMD7) is used to select one card and place it in the
Transfer State. If a previously selected card is in the Transfer State its connection with the host is released
and it will move back to the Stand-by State. Only one card can be, at any time, in the Transfer State. A
selected card is responding the CMD7, the deselected one does not respond to this command. When
CMD7 is sent including the reserved relative card address 0x0000, all cards transfer back to Stand-by State.
This command is used to identify new cards without resetting other already acquired cards. Cards to which
an RCA has already been assigned, do not respond to the identification command flow in this state. All the
data communication in the Data Transfer Mode is consequently a point-to point communication between
the host and the selected card (using addressed commands). All addressed commands are acknowledged
by a response on the CMD line. All read commands (data is sent from the card via data lines) can be
interrupted at any time, by a stop command. The data transfer will terminate and the card will stop or start
working on the next command. The DAT bus line signal level is high when no data is transmitted. A
transmitted data block consists of a start bit (LOW), followed by a continuous data stream. The data
stream contains the net payload data (and error correction bits if an off-card ECC is used). The data stream
Rev.0.02, Sep.15.2004, page 35 of 89
HB28K032/L064/J128/J256/J512MM3, HB28K032/L064/J128/J256RM3
ends with an end bit (HIGH). The data transmission is synchronous to the clock signal. The payload for
block-oriented data transfer is preserved by a 16-bit CRC check sum (refer to Chapter “Cyclic Redundancy
Check (CRC)”).
• Stream read
There is a stream oriented data transfer controlled by READ_DAT_UNTIL_STOP (CMD11). This
command instructs the card to send its payload, starting at a specified address, until the host sends a
STOP_TRANSMISSION command (CMD12). The stop command has an execution delay due to the serial
command transmission. The data transfer stops after the end bit of the stop command. If the end of the
memory range is reached while sending data and no stop command has been sent yet by the host, the
contents of the further transferred payload is undefined. The maximum clock frequency for stream read
operation is given by the following formula:
max. speed = min (TRAN_SPEED, (8 * 2
READ_BL_LEN
− NSAC) / TAAC),
= min (20, (8 * 2 ) − 100 [cycles]) / 1000 [µs]) [MHz]
9
= min (20, 3.996) 3.996 [MHz]
these parameters being defined in Chapter “Registers”. If the host attempts to use a higher frequency, the
card may not be able to sustain data transfer. If this happens, the card will set the UNDERRUN error bit in
the status register, abort the transmission and wait in the data state for a stop command.
• Block read
The basic unit of data transfer is a block whose maximum size is defined in the CSD (READ_BLK_LEN).
READ_BLK_PARTIAL is set, thus smaller blocks whose starting and ending address are wholly contained
within one physical block (as defined by READ_BLK_LEN) may also be transmitted. A 16-bit CRC is
appended to the end of each block ensuring data transfer integrity. READ_SINGLE_BLOCK (CMD17)
starts a block read and after a complete transfer the card goes back to Transfer State.
READ_MULTIPLE_BLOCK (CMD18) starts a transfer of several consecutive blocks. Two types of
multiple block read transactions are defined (the host can use either one at any time):
• Open-ended Multiple block read
The number of blocks for the read multiple block operation is not defined. The card will
continuously transfer data blocks until a stop transmission command is received.
• Multiple block read with pre-defined block count
The card will transfer the requested number of data blocks, terminate the transaction and return to
transfer state. Stop command is not required at the end of this type of multiple block read, unless
terminated with an error. In order to start a multiple block read with pre-defined block count, the
host must use the SET_BLOCK_COUNT command (CMD23) immediately preceding the
READ_MULTIPLE_BLOCK (CMD18) command. Otherwise the card will start an open-ended
multiple block read which can be stopped using the STOP_TRANSMISSION command.
The host can abort reading at any time, within a multiple block operation, regardless of the its type.
Transaction abort is done by sending the stop transmission command.
Rev.0.02, Sep.15.2004, page 36 of 89
HB28K032/L064/J128/J256/J512MM3, HB28K032/L064/J128/J256RM3
If the card detects an error (e.g. out of range, address misalignment, internal error, etc.) during a multiple
block read operation (both types) it will stop data transmission and remain in the Data State. The host must
than abort the operation by sending the stop transmission command. The read error is reported in the
response to the stop transmission command.
If the host sends a stop transmission command after the card transmits the last block of a multiple block
operation with a pre-defined number of blocks, it will be responded to as an illegal command, since the
card is no longer in data state.
If the host uses partial blocks whose accumulated length is not block aligned and block misalignment is not
allowed, the card shall detect a block misalignment error condition at the beginning of the first misaligned
block (ADDRESS_ERROR error bit will be set in the status register).
• Stream write
Stream write (CMD20) starts the data transfer from the host to the card beginning from the starting address
until the host issues a stop command. If partial blocks are allowed (if CSD parameter
WRITE_BL_PARTIAL is set) the data stream can start and stop at any address within the card address
space, otherwise it shall start and stop only at block boundaries. Since the amount of data to be transferred
is not determined in advance, CRC can not be used. If the end of the memory range is reached while
sending data and no stop command has been sent by the host, all further transferred data is discarded. The
maximum clock frequency for stream write operation is given by the following formula:
max. speed = min (TRAN_SPEED, (8 * 2
− NSAC) / (TAAC * R2W_FACTOR))
9
= min (20, (8 * 2 − 100 [cycles]) / 1000 [µs] * 4)[MHz] = min (20, 0.999) = 0.999 [MHz]
WRITE_BL_LEN
these parameters being defined in Chapter “Registers”. If the host attempts to use a higher frequency, the
card may not be able to process the data and will stop programming, set the OVERRUN error bit in the
status register, and while ignoring all further data transfer, wait (in the Receive-data-State) for a stop
command. The write operation shall also be aborted if the host tries to write over a write-protected area.
In this case, however, the card shall set the WP_VIOLATION bit.
• Block write
Block write (CMD24 − 27) means that one or more blocks of data are transferred from the host to the card
with a 16-bit CRC appended to the end of each block by the host. A card supporting block write must
always be able to accept a block of data defined by WRITE_BLK_LEN. If the CRC fails, the card will
indicate the failure on the DAT line; the transferred data will be discarded and not written and all further
transmitted blocks (in multiple block write mode) will be ignored.
WRITE_MULTIPLE_BLOCK (CMD25) starts a transfer of several consecutive blocks. Two types of
multiple block write transactions, identical to the multiple block read, are defined (the host can use either
one at any time):
• Open-ended Multiple block write
The number of blocks for the write multiple block operation is not defined. The card will
continuously accept and program data blocks until a stop transmission command is received.
Rev.0.02, Sep.15.2004, page 37 of 89
HB28K032/L064/J128/J256/J512MM3, HB28K032/L064/J128/J256RM3
• Multiple block write with pre-defined block count
The card will transfer the requested number of data blocks, terminate the transaction and return to
transfer state. Stop command is not required at the end of this type of multiple block write, unless
terminated with an error. In order to start a multiple block write with pre-defined block count, the
host must use the SET_BLOCK_COUNT command (CMD23) immediately preceding the
WRITE_MULTIPLE_BLOCK (CMD25) command. Otherwise the card will start an open-ended
multiple block write which can be stopped using the STOP_TRANSMISSION command.
The host can abort writing at any time, within a multiple block operation, regardless of the its type.
Transaction abort is done by sending the stop transmission command. If a multiple block write with
predefined block count is aborted, the data in the remaining blocks is not defined.
If the card detects an error (e.g. write protect violation, out of range, address misalignment, internal error,
etc.) during a multiple block write operation (both types) it will ignore any further incoming data blocks
and remain in the Receive State. The host must than abort the operation by sending the stop transmission
command. The write error is reported in the response to the stop transmission command.
If the host sends a stop transmission command after the card received the last block of a multiple block
write with a pre-defined number of blocks, it will be responded to as an illegal command, since the card is
no longer in rcv state.
If the host uses partial blocks whose accumulated length is not block aligned and block misalignment is not
allowed (CSD parameter WRITE_BLK_MISALIGN is not set), the card will detect the block misalignment
error and abort programming before the beginning of the first misaligned block. The card will set the
ADDRESS_ERROR error bit in the status register, and wait (in the Receive-data-State) for a stop
command while ignoring all further data transfer. The write operation will also be aborted if the host tries
to write over a write-protected area. In this case, however, the card will set the WP_VIOLATION bit.
Programming of the CID and CSD register does not require a previous block length setting. The
transferred data is also CRC protected.
• Erase
Identification of these erase groups is accomplished with the TAG_ERASE_GROUP commands. A first
command with the starting address is followed by a second command with the final address, and all erase
groups within this range will be selected for erase. The host must adhere to the following command
sequence; TAG_ERASE_GROUP_START, TAG_ERASE_GROUP_END and ERASE. The following
exception conditions are detected by the card: An erase or tag command is received out of sequence. The
card will set the ERASE_SEQUENCE error bit in the status register and reset the whole sequence. An out
of sequence command (except SEND_STATUS) is received. The card will set the ERASE_RESET status
bit in the status register, reset the erase sequence and execute the last command. If the erase range includes
write protected erase groups, they will be left intact and only the non-protected erase groups will be erased.
The WP_ERASE_SKIP status bit in the status register will be set. The address field in the tag commands
is an erase group. The card will ignore all LSB’s below the group size. As described above for block
write, the card will indicate that an erase is in progress by holding DAT low. The actual erase time may be
quite long, and the host may choose to deselect the card using CMD7.
Rev.0.02, Sep.15.2004, page 38 of 89
HB28K032/L064/J128/J256/J512MM3, HB28K032/L064/J128/J256RM3
• Write protect management
Card data may be protected against either erase or write. The entire card may be permanently write
protected by the manufacturer or content provider by setting the permanent or temporary write protect bits
in the CSD. Portions of the data may be protected (in units of WP_GRP_SIZE sectors as specified in the
CSD), and the write protection may be changed by the application. The SET_WRITE_PROT command
sets the write protection of the addressed write-protect group, and the CLR_WRITE_PROT command
clears the write protection of the addressed write-protect group. The SEND_WRITE_PROT command is
similar to a single block read command. The card shall send a data block containing 32 write protection
bits (representing 32 write protect groups starting at the specified address) followed by 16 CRC bits. The
address field in the write protect commands is a group address in byte units. The card will ignore all LSB’s
below the group size.
• Card lock/unlock operation
The password protection feature enables the host to lock a card while providing a password, which later
will be used for unlocking the card. The password and its size are kept in a 128-bit PWD and 8-bit
PWD_LEN registers, respectively. These registers are non-volatile so that a power cycle will not erase
them. Locked cards respond to (and execute) all commands in the "basic" command class (class 0) and
“lock card” command class. Thus the host is allowed to reset, initialize, select, query for status, etc., but
not to access data on the card. If the password was previously set (the value of PWD_LEN is not‘0’) will
be locked automatically after power on. Similar to the existing CSD and CID register write commands the
lock/unlock command is available in "transfer state" only. This means that it does not include an address
argument and the card has to be selected before using it. The card lock/unlock command has the structure
and bus transaction type of a regular single block write command. The transferred data block includes all
the required information of the command (password setting mode, PWD itself, card lock/unlock etc.). The
following table describes the structure of the command data block.

• ERASE: 1 Defines Forced Erase Operation (all other bits shall be ‘0’) and only the cmd byte is
sent.
• LOCK/UNLOCK: 1 = Locks the card. 0 = Unlock the card (note that it is valid to set this bit
together with SET_PWD but it is not allowed to set it together with CLR_PWD).
• CLR_PWD: 1 = Clears PWD.
• SET_PWD: 1 = Set new password to PWD.
• PWD_LEN: Defines the following password length (in bytes).
• PWD: The password (new or currently used depending on the command).
The data block size shall be defined by the host before it sends the card lock/unlock command. This will
allow different password sizes. The following paragraphs define the various lock/unlock command
sequences:
• Setting the Password
 Select a card (CMD7), if not previously selected already.
 Define the block length (CMD16), given by the 8bit card lock/unlock mode, the 8-bit
password size (in bytes), and the number of bytes of the new password. In case that a password
replacement is done, then the block size shall consider that both passwords, the old and the new
one, are sent with the command.
 Send Card Lock/Unlock command with the appropriate data block size on the data line
including 16-bit CRC. The data block shall indicate the mode (SET_PWD), the length
(PWD_LEN) and the password itself. In case that a password replacement is done, then the
length value (PWD_LEN) shall include both passwords, the old and the new one, and the PWD
field shall include the old password (currently used) followed by the new password.
 In case that the sent old password is not correct (not equal in size and content) then
LOCK_UNLOCK_FAILED error bit will be set in the status register and the old password does
not change. In case that PWD matches the sent old password then the given new password and
its size will be saved in the PWD and PWD_LEN fields, respectively.
Note that the password length register (PWD_LEN) indicates if a password is currently set. When it equals
‘0’ there is no password set. If the value of PWD_LEN is not equal to zero the card will lock itself after
power up. It is possible to lock the card immediately in the current power session by set-ting the
LOCK/UNLOCK bit (while setting the password) or sending additional command for card lock.
• Reset the Password:
 Select a card (CMD7), if not previously selected already.
 Define the block length (CMD16), given by the 8 bit card lock/unlock mode, the 8 bit
password size (in bytes), and the number of bytes of the currently used password.
 Send the card lock/unlock command with the appropriate data block size on the data line
including 16-bit CRC. The data block shall indicate the mode CLR_PWD, the length
(PWD_LEN) and the password (PWD) itself (LOCK/UNLOCK bit is don’t care). If the PWD
and PWD_LEN content match the sent password and its size, then the content of the PWD
register is cleared and PWD_LEN is set to 0. If the password is not correct then the
LOCK_UNLOCK_FAILED error bit will be set in the status register.

• Locking a card:
 Select a card (CMD7), if not previously selected already.
 Define the block length (CMD16), given by the 8 bit card lock/unlock mode, the 8 bit
password size (in bytes), and the number of bytes of the currently used password.
 Send the card lock/unlock command with the appropriate data block size on the data line
including 16-bit CRC. The data block shall indicate the mode LOCK, the length (PWD_LEN)
and the password (PWD) itself.
If the PWD content equals to the sent password then the card will be locked and the card-locked status bit
will be set in the status register. If the password is not correct then LOCK_UNLOCK_FAILED error bit
will be set in the status register. Note that it is possible to set the password and to lock the card in the same
sequence. In such case the host shall perform all the required steps for setting the password (as described
above) including the bit LOCK set while the new password command is sent. If the password was
previously set (PWD_LEN is not ‘0’), then the card will be locked automatically after power on reset. An
attempt to lock a locked card or to lock a card that does not have a password will fail and the
LOCK_UNLOCK_FAILED error bit will be set in the status register.
• Unlocking the card:
 Select a card (CMD7), if not previously selected already.
 Define the block length (CMD16), given by the 8 bit card lock/unlock mode, the 8 bit
password size (in bytes), and the number of bytes of the currently used password.
 Send the card lock/unlock command with the appropriate data block size on the data line
including 16-bit CRC. The data block shall indicate the mode UNLOCK, the length
(PWD_LEN) and the password (PWD) itself.
If the PWD content equals to the sent password then the card will be unlocked and the card-locked status
bit will be cleared in the status register. If the password is not correct then the LOCK_UNLOCK_FAILED
error bit will be set in the status register. Note that the unlocking is done only for the current power
session. As long as the PWD is not cleared the card will be locked automatically on the next power up.
The only way to unlock the card is by clearing the password. An attempt to unlock an unlocked card will
fail and LOCK_UNLOCK_FAILED error bit will be set in the status register.
• Forcing Erase:
In case that the user forgot the password (the PWD content) it is possible to erase all the card data content
along with the PWD content. This operation is called Forced Erase.
 Select a card (CMD7), if not previously selected already.
 Define the block length (CMD16) to 1 byte (8bit card lock/unlock command). Send the card
lock/unlock command with the appropriate data block of one byte on the data line including 16bit CRC. The data block shall indicate the mode ERASE (the ERASE bit shall be the only bit
set).
If the ERASE bit is not the only bit in the data field then the LOCK_UNLOCK_FAILED error bit will be
set in the status register and the erase request is rejected. If the command was accepted then ALL THE
CARD CONTENT WILL BE ERASED including the PWD and PWD_LEN register content and the
locked card will get unlocked. An attempt to force erase on an unlocked card will fail and
LOCK_UNLOCK_FAILED error bit will be set in the status register.

Format R1b (response command with busy signal):
R1b is identical to R1 with an optional busy signal transmitted on the data line. The card may become
busy after receiving these commands based on its state prior to the command reception.
Format R2 (CID, CSD register): response length 136 bits.
Note: Bit 127 down to bit 1 of CID and CSD are transferred, the reserved bit [0] is replaced by the end bit.

The OCR is sent as a response to the CMD1 to signalize the supported voltage range. These Renesas
MultiMediaCards support the range from 2.7 V to 3.6 V. Respectively the value of all bits of the OCR
field of these Renesas MultiMediaCards is set to 0x80FF8000. So the R3 frame contains the value
0x3F80FF8000FF if the card is ready and 0x3F00FF8000FF if the card is busy.

Status
The response format R1 contains a 32-bit field with the name card status. This field is intended to transmit
status information which is stored in a local status register of each card to the host. The following table
defines the status register structure. The Type and Clear-Condition fields in the table are coded as follows:
• Type:
• E: Error bit.
• S: Status bit.
• R: Detected and set for the actual command response.
• X: Detected and set during command execution. The host must poll the card by sending status
command in order to read these bits.
• Clear Condition:
• A: According to the card state.
• B: Always related to the previous command. Reception of a valid command will clear it (with a
delay of one command).
• C: Clear by read.

Command Response Timings
All timing diagrams use the following schematics and abbreviations:
S: Start bit (= 0)
T: Transmitter bit (Host = 1, Card = 0)
P: One-cycle pull-up (= 1)
E: End bit (= 1)
Z: High impedance state (-> = 1)
D: Data bits
*: Repeater
CRC: Cyclic redundancy check bits (7 bits for command or response, 16 bits for block data)
The difference between the P-bit and Z-bit is that a P-bit is actively driven to HIGH by the card
respectively host output driver, while the Z-bit is driven to (respectively kept) HIGH by the pull-up
resistors RCMD respectively RDAT. Actively driven P-bits are less sensitive to noise superposition. For the
timing of these Renesas MultiMediaCards, the following values are defined:

• Stream read
The data transfer starts NAC clock cycles after the end bit of the host command. The bus transaction is
identical to that of a read block command (refer to Figure “Data Read Timing”). As the data transfer is not
block-oriented, the data stream does not include the CRC checksum. Consequently the host can not check
for data validity. The data stream is terminated by a stop command. The corresponding bus transaction is
identical to the stop command for the multiple read block (refer to Figure “Timing of Stop Command”).
• Single or multiple block write
The host selects one card for data write operation by CMD7. The host sets the valid block length for
block-oriented data transfer by CMD16 (The write-block-length of the Renesas MultiMediaCard is
permanently assigned to the value 512 bytes). The host transfers the data with CMD24. The address of the
data block is determined by the argument of this command. This command is responded by the card on the
CMD line as usual. The data transfer from the host starts NWR clock cycles after the card response was
received. The write data have CRC check bits to allow the card to check the transferred data for
transmission errors. The card sends the CRC check information as a CRC status to the host (on the data
line). The CRC status contains the information if the write data transfer was non-erroneous (the CRC
check did not fail) or not. In the case of transmission error the card sends a negative CRC status (“101”
bin) which forces the host to retransmit command and the data. In the case of non-erroneous transmission
the card sends a positive CRC status (“010” bin) and starts the data programming procedure.

Timing of The Block Write Command
If the card does not have any more free data receive buffer, the card indicates it by pulling down the data
line to LOW. The card stops pulling down the data line as soon as at least one receive buffer for the
defined data transfer block length becomes free. This signaling does not give any information about the
data write status. This information has to be polled by CMD13 polling command (SEND_STATUS).

HB28K032/L064/J128/J256/J512MM3, HB28K032/L064/J128/J256RM3
• Stream write
The data transfer starts NWR clock cycles after the card response to the sequential write command was
received. The bus transaction is identical to that of a write block command (see Figure “Timing of The
Block Write Command”). As the data transfer is not block-oriented, the data stream does not include the
CRC checksum. Consequently the host can not receive any CRC status information from the card. The
data stream is terminated by a stop command. The bus transaction is identical to the write block option
when a data block is interrupted by the stop command (see Figure “Stop Transmission During Data
Transfer From The Host”).

• Erase block timing
The host must first tag the group to erase. The tagged group(s) are erased in parallel by using the CMD35,
CMD36 and CMD38. The card busy signaling is also used for the indication of the card erase procedure
duration. In this case the end of the card busy signaling also does mean that the erase of all tagged groups
has been finished. The host can (also) request the card to send the actual card state using the CMD13.

Reset
GO_IDLE_STATE (CMD0) is the software reset command, which sets the MultiMediaCard into the Idle
State independently of the current state. In the Inactive State the MultiMediaCard is not affected by this
command. After power-on the MultiMediaCard is always in the Idle State. After power-on or command
GO_IDLE_STATE (CMD0) all output bus drivers of the MultiMediaCard is in a high-impedance state and
the card will be initialized with a default relative card address (0x0001). The host runs the bus at the
identification clock rate fOD generated by a push-pull driver stage (refer to also Chapter “Power on” for
more details).
CMD0 is valid in all states with the exception of the Inactive State. While in Inactive state the card will not

SPI Communication
The SPI mode consists of a secondary communication protocol. This mode is a subset of the
MultiMediaCard protocol, designed to communicate with a SPI channel, commonly found in Motorola’s
(and lately a few other vendors’) microcontrollers. The interface is selected during the first reset command
after power up (CMD0) and cannot be changed once the part is powered on. The SPI standard defines the
physical link only, and not the complete data transfer protocol. The MultiMediaCard SPI implementation
uses a subset of the MultiMediaCard protocol and command set. It is intended to be used by systems
which require a small number of card (typically one) and have lower data transfer rates (compared to
MultiMediaCard protocol based systems). From the application point of view, the advantage of the SPI
mode is the capability of using an off-the-shelf host, hence reducing the design-in effort to minimum. The
disadvantage is the loss of performance of the SPI system versus MultiMediaCard (lower data transfer rate,
fewer cards, hardware CS per card etc.). While the MultiMediaCard channel is based on command and
data bitstreams which are initiated by a start bit and terminated by a stop bit, the SPI channel is byte
oriented. Every command or data block is built of 8-bit bytes and is byte aligned to the CS signal (i.e. the
length is a multiple of 8 clock cycles). Similar to the MultiMediaCard protocol, the SPI messages consist
of command, response and data-block tokens (refer to Chapter “Commands” and Chapter “Responses” for
a detailed description). All communication between host and cards is controlled by the host (master). The
host starts every bus transaction by asserting the CS signal low. The response behavior in the SPI mode
differs from the MultiMediaCard mode in the following three aspects:
• The selected card always responds to the command.
• An additional (8 bit) response structure is used.
• When the card encounters a data retrieval problem, it will respond with an error response (which
replaces the expected data block) rather than by a time-out as in the MultiMediaCard mode.
Single block and multiple read and write operations are supported in SPI mode. In addition to the
command response, every data block sent to the card during write operations will be responded with a
special data response token. A data block may be as big as one card sector and as small as a single byte.
Partial block read/write operations are enabled by card options specified in the CSD register.
Mode Selection
The MultiMediaCard wakes up in the MultiMediaCard mode. It will enter SPI mode if the reset command
(CMD0) is received during the CS signal is asserted (negative). Selecting SPI mode is not restricted to Idle
state (the state the card enters after power up) only. Every time the card receives CMD0, including while
in Inactive state, CS signal is sampled.
If the card recognizes that the MultiMediaCard mode is required it will not respond to the command and
remain in the MultiMediaCard mode. If SPI mode is required the card will switch to SPI and respond with
the SPI mode R1 response.
The only way to return to the MultiMediaCard mode is by entering the power cycle. In SPI mode the
MultiMediaCard protocol state machine is not observed. All the MultiMediaCard commands supported in
SPI mode are always available.

HB28K032/L064/J128/J256/J512MM3, HB28K032/L064/J128/J256RM3
Bus Transfer Protection
Every MultiMediaCard token transferred on the bus is protected by CRC bits. In SPI mode, the
MultiMediaCard offers a non-protected mode which enables systems built with reliable data links to
exclude the hardware or firmware required for implementing the CRC generation and verification
functions. In the non-protected mode the CRC bits of the command, response and data tokens are still
required in the tokens. However, they are defined as “don’t care” for the transmitter and ignored by the
receiver. The SPI interface is initialized in the non protected mode. However, the RESET command
(CMD0), which is used to switch the card to SPI mode, is received by the card while in MultiMediaCard
mode and, therefore, must have a valid CRC field.
The host can turn this option on and off using the CRC_ON_OFF command (CMD59).
Data Read Overview
The SPI mode supports single and multiple block read operations (CMD17 and CMD18 in the
MultiMediaCard protocol). The main difference between SPI and MultiMediaCard modes is that the data
and the response are both transmitted to the host on the DataOut signal (refer to Figure 43 and Figure 45).
Therefore the card response to the STOP_COMMAND may cut-short and replace the last data block (refer
to Figure “Read Operation”).

Multiple Block Read Operation
The basic unit of data transfer is a block whose maximum size is defined in the CSD (READ_BL_LEN). If
READ_BL_PARTIAL is set, smaller blocks whose starting and ending addresses are entirely contained
within one physical block (as defined by READ_BL_LEN) may also be transmitted. A 16-bit CRC is
appended to the end of each block ensuring data transfer integrity (also refer to chapter “Cyclic
Redundancy Check (CRC)”). CMD17 (READ_SINGLE_BLOCK) initiates a single block read. CMD18
Rev.0.02, Sep.15.2004, page 55 of 89
HB28K032/L064/J128/J256/J512MM3, HB28K032/L064/J128/J256RM3
(READ_MULTIPLE_BLOCK) starts a transfer of several consecutive blocks. Two types of multiple
block read transactions are defined (the host can use either one at any time):
• Open-ended Multiple block read
The number of blocks for the read multiple block operation is not defined. The card will
continuously transfer data blocks until a stop transmission command is received.
• Multiple block read with pre-defined block count
The card will transfer the requested number of data blocks, terminate the transaction and return to
transfer state. Stop command is not required at the end of this type of multiple block read, unless
terminated with an error. In order to start a multiple block read with pre-defined block count, the
host must use the SET_BLOCK_COUNT command (CMD23) immediately preceding the
READ_MULTIPLE_BLOCK (CMD18) command. Otherwise the card will start an open-ended
multiple block read which can be stopped using the STOP_TRANSMISSION command.
The host can abort reading at any time, within a multiple block operation, regardless of the its type.
Transaction abort is done by sending the stop transmission command.
In case of a data retrieval error, the card will not transmit any data. Instead, a special data error token will
be sent to the host. Figure “Read Operation-Data Error” shows a data read operation which terminated
with an error token rather than a data block.

Read Operation-Data Error
Data Write Overview
As for the read operation, while in SPI mode the MultiMediaCard supports single and multiple block write
commands. Upon reception of a valid write command (CMD24 and CMD25 in the MultiMediaCard
protocol), the card will respond with a response token and will wait for a data block to be sent from the
host. CRC suffix, block length and start address restrictions are (with the exception of the CSD parameter
WRITE_BL_PARTIAL controlling the partial block write option) identical to the read operation (refer to
Figure “Single Block Write Operation”). If a CRC error is detected it will be reported in the data-response
token and the data block will not be programmed.

Single Block Write Operation
After a data block has been received, the card will respond with a data-response token. If the data block
has been received without errors, it will be programmed. As long as the card is busy programming, a
continuous stream of busy tokens will be sent to the host (effectively holding the DataOut line low).
In Multiple Block write operation the stop transmission will be done by sending ‘Stop Tran’ token instead
of ‘Start Block’ token at the beginning of the next block.

Multiple Block Write Operation
Two types of multiple block write transactions, identical to the multiple block read, are defined (the host
can use either one at any time):
• Open-ended Multiple block write
The number of blocks for the write multiple block operation is not defined. The card will
continuously accept and program data blocks until a ‘Stop Tran’ token is received.
• Multiple block write with pre-defined block count
The card will accept the requested number of data blocks and terminate the transaction. ‘Stop Tran’
token is not required at the end of this type of multiple block write, unless terminated with an error.
In order to start a multiple block write with pre-defined block count, the host must use the
SET_BLOCK_COUNT command (CMD23) immediately preceding the
WRITE_MULTIPLE_BLOCK (CMD25) command. Otherwise the card will start an open-ended
multiple block write which can be stopped using the ‘Stop Tran’ token.
The host can abort writing at any time, within a multiple block operation, regardless of the its type.
Transaction abort is done by sending the ‘Stop Tran’ token. If a multiple block write with predefined
block count is aborted, the data in the remaining blocks is not defined.
If the card detects a CRC error or a programming error (e.g. write protect violation, out of range, address
misalignment, internal error, etc.) during a multiple block write operation (both types) it will report the
Rev.0.02, Sep.15.2004, page 57 of 89
HB28K032/L064/J128/J256/J512MM3, HB28K032/L064/J128/J256RM3
failure in the data-response token and ignore any further incoming data blocks. The host must than abort
the operation by sending the ‘Stop Tran’ token.
If the host uses partial blocks whose accumulated length is not block aligned and block misalignment is not
allowed (CSD parameter WRITE_BLK_MISALIGN is not set), the card shall detect the block
misalignment error before the beginning of the first misaligned block and respond with an error indication
in the dataresponse token and ignore any further incoming data blocks. The host must than abort the
operation by sending the ‘Stop Tran’ token.
Once the programming operation is completed, the host must check the results of the programming using
the SEND_STATUS command (CMD13). Some errors (e.g. address out of range, write protect violation
etc.) are detected during programming only. The only validation check performed on the data block and
communicated to the host via the data-response token is the CRC.
If the host sends a ‘Stop Tran’ token after the card received the last block of a multiple block operation
with pre-defined number of blocks, it will be responded to as the beginning of an illegal command and
responded accordingly.
While the card is busy, resetting the CS signal will not terminate the programming process. The card will
release the DataOut line (tri-state) and continue with programming. If the card is reselected before the
programming is finished, the DataOut line will be forced back to low and all commands will be rejected.
Resetting a card (using CMD0) will terminate any pending or active programming operation. This may
destroy the data formats on the card. It is in the responsibility of the host to prevent it.

Erase and Write Protect Management
The erase and write protect management procedures in the SPI mode are identical to those of the
MultiMediaCard mode. While the card is erasing or changing the write protection bits of the predefined
sector list, it will be in a busy state and hold the DataOut line low. Figure “No Data Operations” illustrates
a ‘no data’ bus transaction with and without busy signaling.

‘No Data’ Operations
Reading CID/CSD Registers
Unlike the MultiMediaCard protocol (where the register contents are sent as a command response), reading
the contents of the CSD and CID registers in SPI mode is a simple read-block transaction. The card will
respond with a standard response token (refer to Figure “Read Operation”) followed by a data block of 16
bytes suffixed with a 16-bit CRC. The data timeout for the CSD command cannot be set to the card TAAC
since this value is stored in the CSD. Therefore the standard response timeout value (NCR) is used for read
latency of the CSD register.
Reset Sequence
The MultiMediaCard requires a defined reset sequence. After power on reset or CMD0 (software reset) the
card enters an idle state. At this state the only legal host command is CMD1 (SEND_OP_COND) and
CMD58 (READ_OCR). In SPI mode, as opposed to MultiMediaCard mode, CMD1 has no operands and
does not return the contents of the OCR register. Instead, the host may use CMD58 (available in SPI mode
only) to read the OCR register. Furthermore, it is in the responsibility of the host to refrain from accessing
cards that do not support its voltage range. The usage of CMD58 is not restricted to the initializing phase
only, but can be issued at any time. The host must poll the card (by repeatedly sending CMD1) until the
‘in-idle-state’ bit in the card response indicates (by being set to 0) that the card completed its initialization
processes and is ready for the next command. The host must poll the card (by repeatedly sending CMD1)
until the ‘in-idle-state’ bit in the card response indicates (by being set to 0) that the card completed its
initialization processes and is ready for the next command.

HB28K032/L064/J128/J256/J512MM3, HB28K032/L064/J128/J256RM3
Error Conditions
Unlike the MultiMediaCard protocol, in the SPI mode the card will always respond to a command. The
response indicates acceptance or rejection of the command. A command may be rejected if it is not
supported (illegal opcode), if the CRC check failed, if it contained an illegal operand, or if it was out of
sequence during an erase sequence.
Memory Array Partitioning
Same as for MultiMediaCard mode.
Card Lock/Unlock
Usage of card lock and unlock commands in SPI mode is identical to MultiMediaCard mode. In both cases
the command response is of type R1b. After the busy signal clears, the host should obtain the result of the
operation by issuing a GET_STATUS command. Please refer to Chapter “Card lock/unlock operation” for
details.
Commands
All the MultiMediaCard commands are 6 bytes long. The command transmission always starts with the
left bit of the bitstring corresponding to the command codeword. All commands are protected by a CRC7.
The commands and arguments are listed in Table:

The following table provides a detailed description of the SPI bus commands. The responses are defined in
Chapter “Responses”. The Table “Commands and Arguments” lists all MultiMediaCard commands. A
“yes” in the SPI mode colon indicates that the command is supported in SPI mode. With these restrictions,
the command class description in the CSD is still valid. If a command does not require an argument, the
value of this field should be set to zero. The reserved commands are reserved in MultiMediaCard mode as
well. The binary code of a command is defined by the mnemonic symbol. As an example, the content of
the command index field is (binary) ‘000000’ for CMD0 and ‘100111’ for CMD39.

Responses
There are several types of response tokens. As in the MultiMediaCard mode, all are transmitted MSB first:
• Format R1
This response token is sent by the card after every command with the exception of SEND_STATUS
commands. It is one byte long, and the MSB is always set to zero. The other bits are error indications, an
error being signaled by a ‘1’. The structure of the R1 format is given in Figure “R1 Response Format”.
The meaning of the flags is defined as following:
• In idle state: The card is in idle state and running the initializing process.
• Erase reset: An erase sequence was cleared before executing because an out of erase sequence
command was received.
• Illegal command: An illegal command code was detected.
• Communication CRC error: The CRC check of the last command failed.
• Erase sequence error: An error in the sequence of erase commands occurred.
• Address error: A misaligned address, which did not match the block length, was used in the
command.
• Parameter error: The command’s argument (e.g. address, block length) was out of the
allowed range for this card.

argument was out of its valid range or if the host is trying to change the ROM section or reverse
the copy bit (set as original) or permanent WP bit (un-protect) of the CSD register.
• Erase param: An invalid selection, groups, for erase.
• Write protect violation: The command tried to write a write protected block.
• Card ECC failed: Card internal ECC was applied but failed to correct the data.
•
CC error: Internal card controller error
• Error: A general or an unknown error occurred during the operation.
• Write protect erase skip  lock/unlock command failed: This status bit has two functions
overloaded. It is set when the host attempts to erase a write protected sector or if a sequence or
password error occurred during card lock/unlock operation.
• Card is locked: Set when the card is locked by the user. Reset when it is unlocked.

Clearing Status Bits
As described in the previous paragraphs, in SPI mode, status bits are reported to the host in three different
formats: response R1, response R2 and data error token (the same bits may exist in multiple response
types e.g. Card ECC failed).
As in the MultiMediaCard mode, error bits are cleared when read by the host, regardless of the response
format. State indicators are either cleared by reading or in accordance with the card state. All Error/Status
bits defined in MultiMediaCard mode, with the exception of underrun and overrun, have the same meaning
and usage in SPI mode. The following table summarizes the set and clear conditions for the various status
bits:
• Type:
• E: Error bit.
• S: Status bit.
• R: Detected and set for the actual command response.
• X: Detected and set during command execution. The host must poll the card by sending status
command in order to read these bits.
• Clear Condition:
• A: According to the card state.
• C: Clear by read.

Error Handling
MultiMediaCards are defined as error free devices or as devices with a defined maximum bit error rate
(with external error correction circuitry). To correct defects in the memory field of the cards the system
may include error correction codes in the payload data (ECC). This correction is intended to correct static
errors. Additionally two methods of detecting errors generated during the data transfer (dynamic errors)
via a cyclic redundancy check (CRC) are implemented.
On Card Error Correction Code (ECC)
These Renesas MultiMediaCards is free of static errors. All errors are covered inside the card, even errors
occurring during the lifetime of these Renesas MultiMediaCards are covered for the user. The only effect
which may be notified by the end user is, that the overall memory capacity may be reduced by small
number of blocks. All flash handling is done on card, so that no external error correction is needed.

HB28K032/L064/J128/J256/J512MM3, HB28K032/L064/J128/J256RM3
Cyclic Redundancy Check (CRC)
The CRC is intended for protecting MultiMediaCard commands, responses and data transfer against
transmission errors on the MultiMediaCard bus. One CRC is generated for every command and checked
for every response on the CMD line. For data blocks one CRC per transferred block is generated. The
CRC is generated and checked as described in the following.
• CRC7
The CRC7 check is used for all commands, for all responses except type R3, and for the CSD and CID
registers. The CRC7 is a 7-bit value and is computed as follows:
7
3
generator polynomial: G(x) = x + x + 1
n
n-1
M(x) = (first bit) * x + (second bit) * x +...+ (last bit) * x
0
7
CRC[6...0] = Remainder [(M(x) * x ) / G(x)]
All CRC registers are initialized to zero. The first bit is the most left bit of the corresponding bitstring (of
the command, response, CID or CSD). The degree n of the polynomial is the number of CRC protected
bits decreased by one. The number of bits to be protected is 40 for commands and responses (n = 39), and
120 for the CSD and CID (n = 119).
• CRC16
The CRC16 is used for payload protection in block transfer mode. The CRC check sum is a 16-bit value
and is computed as follows:
16
12
5
generator polynomial: G(x) = x + x +x + 1
n
M(x) = (first bit) * x + (second bit) * x
n-1
+...+ (last bit) * x
0
16
CRC[15...0] = Remainder [(M(x) * x ) / G(x)]
All CRC registers are initialized to zero. The first bit is the first data bit of the corresponding block. The
degree n of the polynomial denotes the number of bits of the data block decreased by one (e.g. n = 4095 for
a block length of 512 bytes). The generator polynomial G(x) is a standard CCITT polynomial. The code
has a minimal distance d = 4 and is used for a payload length of up to 2048 Bytes (n ≤ 16383).

Power Supply
Power Supply Decoupling
The VSS1, VSS2 and VCC lines supply the card with operating voltage. For this, decoupling capacitors for
buffering current peak are used. These capacitors are placed on the bus side corresponding to Figure

Power on / off
Each card has its own power on detection circuitry which puts the card into a defined state after the poweron. No explicit reset signal is necessary. The cards can also be reset by a special software command:
GO_IDLE_STATE (CMD0). In case of emergency the host may also reset the cards by switching the
power supply off and on again.

Power on Detection
A power on reset is generated on chip as long as VCC is below a certain limit. After this reset the command
parser of these Renesas MultiMediaCards works properly but the access to the memory core is not
guaranteed. So in the power up phase (or when these Renesas MultiMediaCards are inserted during power
up) the host has to wait after sending SEND_OP_COND (CMD1) for the identification delay before the
ALL_SEND_CID (CMD2) can be interpreted by the card:

Power-up Diagram
• After power up (including hot insertion, i.e. inserting a card when the bus is operating) the
MultiMediaCard enters the idle state. During this state the MultiMediaCard ignores all bus transactions
until CMD1 is received.
• CMD1 is a special synchronization command used to negotiate the operation voltage range and to poll
the cards until they are out of their power-up sequence. Besides the operation voltage pro-file of the
cards, the response to CMD1 contains a busy flag, indicating that the card is still working on its powerup procedure and is not ready for identification. This bit informs the host that at least one card is not
ready. The host has to wait (and continue to poll the cards) until this bit is cleared.
• Getting individual cards, as well as the whole MultiMediaCard system, out of idle state is up to the
responsibility of the bus master. Since the power up time and the supply ramp up time depend on
application parameters such as the maximum number of MultiMediaCards, the bus length and the
power supply unit, the host must ensure that the power is built up to the operating level (the same level
which will be specified in CMD1) before CMD1 is transmitted.
• After power up the host starts the clock and sends the initializing sequence on the CMD line. This
sequence is a contiguous stream of logical ‘1’s. The sequence length is the maximum of 1 msec, 74
clocks or the supply-ramp-up-time; The additional 10 clocks (over the 64 clocks after what the card
should be ready for communication) are provided to eliminate power-up synchronization problems.
• When the power is on after the power down, VCC must be 0.25 V or less.

Short Cut Protection
The MultiMediaCards can be inserted/removed into/from the bus without damage.
If one of the supply pins (VCC or VSS) is not connected properly, then the current is drawn through a data
line to supply the card. Naturally the card can not operate properly under this conditions.

Timing Diagram of Data Input and Output
The access time (tAT) is divided into two parts:
• TSAD: The synchronous access time. This time defines the time of the maximum number of cycles
which are required to access a byte of the memory field.
• TAAD: The asynchronous access time to read a byte out of the memory field.
The synchronous part of the access time is sum of the command frame length and some additional internal
cycles (NSAD = 16 cycles). At 20 MHz one cycle is 50 ns (1/fPP), multiplied with NSAD the resulting frame
time is TSAD = 0.8 µs. The asynchronous access delay of these Renesas MultiMediaCards is TAAD = 300 µs
typical. The resulting memory access time tAT is the sum of both parts:
tAT = TAAD + TSAD
with
TSAD = NSAD / fPP

1. Refer to Chapter “Read, Write and Erase Time-out Conditions”.
In the CSD are two fields to code the asynchronous and the synchronous access delay time:
• TAAC, asynchronous access delay
• NSAC, maximum number of cycles for receiving and interpreting of a command frame
The value for the CSD field NSAC is calculated from NSAD (maximum: 16 cycles) by division with 100
and rounding up to the next integer:
NSAC = [NSAD/100] = [16/100]
• NSAC = 0x01
The value for the CSD field TAAC is 1 ms:
TAAC = [TAAD] = 1 ms
• TAAC = 0x0E
For more details on NSAC and TAAC CSD-entries refer to Chapter “Card Specific Data (CSD)”.
