This interface connects to the SD memory card slot to communicate with the SD memory device.
Supports the SPI mode.
Supports SD, SDHC memory cards and MMC, mini-SD and micro-SD cards.
Does not support CPRM.
Since the SD memory card slot needs to detect the insertion status of the SD memory device and the write-protect status,
be sure to use the slot having the SD memory card insertion status detection terminal and the WP terminal and connect it
to the terminals. The SD_CON terminal is pulled up within the device and detects “SD card connect” when L is input.
The SD_WP terminal is pulled up within the device and detects “SD card no-write-protect” when L is input.
SD I/F is also used as an external serial flash ROM I/F.

Figure 21. SPDIF Output Format
One sub frame of SPDIF consists of synchronous preambles, 16-bit audio data, V bit (validity flag), U bit (user data), C
bit (channel status) and P bit (parity bit).
Output rate is fixed to 1X speed (44.1 kHz).
SPDIF outputs synchronous preambles (source code 0-3) as they are, and other elements (source code 4-31) as the
biphase output. While the operation stops, L output is enabled.
Synchronous preambles and C bit use 32 frames (≈4.4 ms) for one cycle. The data formats are shown in Table 4 and
Table 5 V bit is fixed to L. U bit uses 98 frames (≈13.3 ms) for one cycle.

P bit is set to 1 if the number of “1” contained in source codes 4-30 is odd, and set to 0 if the number is even.
Therefore, the number of source codes to be set to 1 for one data must be even, SPDIF ends with L output, and
preamble output always starts in the same direction.

This is an I2C serial interface terminal to communicate with the microcomputer (master).
It supports slave I2C operations.
Supports the standard mode (100kbps) and the fast mode (400kbps).
Supports 7-bit addresses.
8.1 I2C protocol
When the I2C bus is in the IDLE state, SDA and SCL are set to H by the external Pull-up resistor.
To start communications, the master sets SDA to L while SCL set to H (Start condition). To finish communications, the
master sets SDA to H while SCL set to H (Stop condition). During transfer, the master changes SDA only while SCL is L.
Figure 23 shows Start condition, Stop condition of I2C.

When sending the received data from the slave to the master using the I2C bus, be sure to conform to the transfer
protocol shown in Figure 26. First, transfer the status read command (step1). Then, input SCL clock of required bytes
in step2 to read the status after BUSY PIN confirms the state of L.
When BUSY PIN is H, correct data is not transmitted.
The first byte of the transferred data (step2) outputs the status shown in Table 9. Data is output from the second byte.

13. System Operation MODE
The LSI starts operation by setting up System Operation MODE after download of the program by IPL after a power
supply and reset release.
Possible operation changes with each modes of operation.
Only the one mode can set up mode of operation with a command.
The mode which is simultaneously different cannot be set up.
A microcomputer sets up the change in System Operation MODE with a command.
It must change via the CONFIG mode when you change the operation mode.
The settlement of the following command is to do a re-setup because it is returned in the initial value when it passes
through the CONFIG mode.

14. File search
14.1 Function
⋅ The file search function supports file system of FAT32, FAT16 and FAT12. (NTFS is not supported.)
⋅ The number of maximum playable files per folder.

The number of files described above includes folders and files other than playable files (WAV/AAC/WMA/MP3). Thus, if
non-playable files or folders contain in the above folders and the number of total files exceeds the maximum limit, all
the playable files may not be played.
⋅ Less than 100 files in the order of FAT within each folder are sorted according to UNICODE. More than 100 files, if
any, will be sorted in the FAT order. The same rule is applied when sorting sub-folders. More than 100 sub-folders, if
any, will be sorted in the FAT order. A sorting function can be selected valid or invalid with a command.
⋅ The folder hierarchies up to 16 hierarchies whose full path including the file name is within 260 characters can be
searched.
⋅ Supports the device size up to FAT specification (2T byte).
⋅ Supports 512, 1024, 2048 and 4096 bytes per sector.
14.2 Playable file
The playable file extension is *.WAV for the WAV file, *.M4A, *.3GP and *.MP4 for the AAC file, *.ASF and *.WMA for
the WMA file, and *.MP3, *.MP2 and *.MP1 for the MP3 file. (There is no distinction between upper case letters and
lower case letters.) Note that the file operation differs in the following cases
⋅ SET_MP3 : For details, see SET_MP3 command.
⋅ Attribute : Files with hidden attributes are also playable. Files with system attributes cannot be played.
⋅ File name : The file name, including its size, does not depend on playability.
⋅ File size : A file with file size "0" is not recognized as a playable file. Playable file size up to 2G-1 byte. A file over
2Gbyte is recognized as a playable file, too. But, it is for 2Gbyte -1byte that it can play.
14.3 File playing sequence
The file playing sequence depends on the following rules when sort function valid. See Figure 35.
[1] Files of 1 to 100, in the order written to FAT (FAT order) in each folder, are sorted in the order of UNICODE.
Files more than 100 are played in the FAT order. The same rule is applied when sorting sub-folders.
MP3 files are sorted for MP3 which conforms to SEL_MP3. All the folders including null ones and those to which
no playable file is written are sorted. If over 100 playable files or sub-folders are contained in the folder, they are
played in the order written to the FAT directory entries.
The writing method of directory entries will not help understand the file play order because the method depends
on the OS operation at writing.
[2] When a playable file exists in the root folder (the top hierarchy), the file is to be played first.
[3] After all the playable files within the root folder have been played, playable files in the folder in the lower hierarchy,
if any, are played.
[4] If another folder exists in the lower hierarchy, playable files within this folder are played. If not, the LSI searches
other folders in the same hierarchy. If another folder exists there, the LSI plays that folder.
[5] After playing all the files, the LSI returns to the root folder as in [2] and play the files starting with the top sorted
one.

14.4 Folder/File sort
The LSI sorts the sub-folders and files in the following sequence:
[1] Obtain up to 100 sub-folders and files each in the order written to FAT within selected folder.
[2] Compare the obtained folder/file names for 14 characters (28 bytes) from the beginning in UNICODE (2-byte
character) and sort them in the ascending order. *
[3] If there are files/folders with same character strings: follow the order of MP3, WMA, AAC and WAV when the
extension is different; and, otherwise, follow the order written to FAT.
[4] 101 or more files or sub-folders follow the order written to FAT.
* The processing of the file name and the folder name is shown in the following.
1)
When a LFN (long file name) entry exists, 2 bytes are treated as one character.
2)
When no LFN entry exists, the SFN (short file name) entry is processed as follows.
2-a) When the first appeared character code is within the range of 0x00-0x7F (US-ASCII), the LSI treats one byte
as one character, and adds '0x00' to the upper of the character to expand the entire character to an
UNICODE.
2-b) For a case other than 2-a), practically, the LSI treats these 2 bytes as one character.
*For details on LFN and SFN, see the FAT file system specifications.

Play order
Remarks
-The LSI first starts playing the playable
files in the root folder, if any.
-The files are played in the ascending
order of UNICODE given to each file
name.
-After playing all the playable files in the
root folder, the LSI searches folders in
the lower hierarchy.
-The folders are searched in the
ascending order of UNICODE given to
each folder name.
-Unplayable files are ignored.
-After playing all the playable files
including those in A_FOLDER and in its
lower hierarchy, the LSI moves to the
hierarchy in which A FOLDER exists and
searches files.
-In this case, since no playable file exists
in D FOLDER, which is in the same
hierarchy of A_FOLDER, the LSI plays
the playable files in E FOLDER in the
further lower hierarchy.
14.5 Search within multi-drive and multi-partition
If a device is a multi-drive type, the LSI recognizes the drive having the smaller LUN (Logical Unit Number) for the
supporting FAT.
Only one drive is recognized and the other drive is not.
For the multi-partition, the LSI recognizes only the first read FAT-supported partition.
Files in other partitions cannot be read.
14.6 External HUB search
When the USB connector is connected to a HUB, and a FAT-supported drive is connected ahead of the HUB at
mounting the USB for this LSI, only one drive is recognized.
The LSI does not support external HUBs, it cannot detect plugging/unplugging of the drive ahead of the HUB after the
USB is mounted.

15. Playing files
15.1 Function
For the files judged to be playable through the file search function, the LSI automatically switches the decoder using
the file extension and decodes these files.
Fast forward play and rewinding play operations are available.
Also, repeat play and random play are available.
When the sample rate of the input file is not 44.1 kHz, the sample after the decode is converted into 44.1 kHz with
sample rate converter (SRC) of building into and output.
15.2 Playable file formats
15.2.1 MP3 file format
This format supports MPEG Audio 1, 2, 2.5 and Layer 1, 2, 3.
It supports sample rates of 8 kHz, 16 kHz, 32 kHz, 11.025 kHz, 22.05 kHz, 44.1 kHz and , 12 kHz, 24 kHz and 48
kHz.
It supports bit rates of 8 to 320kbps and VBR (Variable Bit Rate).
15.2.2 WMA file format
This format supports WMA Ver.9 Standard.
It supports sample rates of 8 kHz, 16 kHz, 32 kHz, 11.025 kHz, 22.05 kHz, 44.1 kHz and 48 kHz.
It supports bit rates of 5 to 384kbps and VBR (Variable Bit Rate).
It does not support DRM.
It supports ASF files including audio streams only.
15.2.3 AAC file format
This format supports MPEG4 AAC-LC.
It conforms to ITunes and 3GPP TS 26.244.
It supports file types of m4a, mp4 and 3gpX. (X is an arbitrary numeric value.)
ITunes is validated in the following versions: 4.*, 5.*, 6.* and 7.0-7.5.
It supports sample rates of 8 kHz, 16 kHz, 32 kHz, 11.025 kHz, 22.05 kHz, 44.1 kHz, 12 kHz, 24 kHz and 48 kHz.
It supports bit rates of 8 to 320kbps and VBR (Variable Bit Rate).
It does not support DRM. It does not support CD-ROM playing.
15.2.4 WAV file format
This format supports RIFF WAVE.
It supports sample rates of 8 kHz, 16 kHz, 32 kHz, 11.025 kHz, 22.05 kHz, 44.1 kHz, 12 kHz, 24 kHz and 48k Hz.
It does not support CD-ROM playing.
15.3 Playing files having damaged data
Operation to the file of all non-correspondence formats is not warrantable. Operation when abnormality of the file is
detected with this LSI is as follows.
If the data section of the MP3 file is damaged, the LSI plays the music data in the possible range instead of ceasing to
play the entire file. It mutes the unplayable section. However, AMUTE terminal remains H output.
If the data section of the WAV file is damaged, noises are output.
The LSI executes other files within the playable range and stops playing. Then, it skips to the next tune.
If a part of the data header is damaged, the LSI immediately terminates playing and skips to the next tune.
If the file’s extension is playable but its file’s data does not have a format supporting to the extension, the LSI
immediately terminates playing and skips to the next tune.
If the file does not have a file format, the LSI immediately terminates playing and skips to the next tune.
However, when the file data is structured in a format other than MP3 and its file extension is *.MP3, *.MP2 or *.MP1,
the LSI plays it in the silence mode basically. However, if the LSI can read any playable data, it plays the file partially.
In this case, the time information which is output as the serial status also becomes unstable. The time information is
then partially output but you cannot obtain the correct information.

The data has a LSI-unique structure.
The resume information data is data of 42 bytes.
It outputs with a little endian.
The above resume information has a LSI-unique structure and is used when executing resume play. Therefore, you
should use the data contents as they are without rewriting.
The resume function is implemented by writing the resume information read by READ_RESUME_INFO command to
PLAY_RESUME command. After writing to PLAY_RESUME, the LSI automatically searches the resume file and plays
it.
After reading READ_RESUME_INFO command during file play, the LSI resumes the file from the time
READ_RESUME_INFO has been read.
The data contents read by READ_RESUME_INFO command cannot assure the operations when executing
PLAY_RESUME which has been rewritten due to the positional information within the memory. If the resume
information does not match because of change of memory, the LSI starts playing the first tune.

16. File browsing within memory
The LSI can analyzing and reading of the entry information of files and subfolders within a folder which is different from
the one having the current tune while the current tune is being played or stopped. Since the read information contains
access data to be used to select tunes, the LSI enables to directly select and play tunes using this data.
The file browsing in the memory operates the cursor (operated position) that can be operated.
When sending the command to move the cursor, the LSI can analyze and read the information of 10 entries (files or
folders) from the move destination. (The number of entries can be changed by the setting of SET_BROWSE_NUM.)
The cursor movement conforms to the sort order determined by the sort function. If the sort function is enabled, the
system first reads the files, and then the subfolders, in the sort order. If the sort function is disabled, the LSI reads the
files and subfolders in the order that they are written to FAT.
A file browsing function becomes effective after ANALYSE_ROOT command is send, and starts the analysis in a root
folder.
When you select music directly by using the access data or cursor position, the following status doesn't return a normal
value because it doesn't understand the number in the whole in the memory.
Playing folder number status in memory, Playing file number status in the memory.

Cautions)
If browsing operation is frequently performed during music plaing, music skipping may occur by the memory with a slow
access speed.
17. Play list play
When PLAY LIST MODE of the system operation mode has been selected, this function is effective.
The LSI can search the play list in the specified folder within the memory and output the play list information.
When the microcomputer selects the play list, the LSI plays the selected tunes in the order written to the play list.
Also, the LSI can output the file information in the selected play list.
Available playlist file should have an extension of M3U or PLS and be described in full path using ASCII or the
SET_LANG command setting.
The full path of a file described in the playlist should be within 256 bytes and within 16 hierarchies.
If the play list format is other than the above or the path does not match, the LSI skip playing tunes.
While playing the tunes in the playlist, PLAY, STOP, PAUSE, FF and FB commands can be used to control the list.
The music file described during the play list is treated as what exists in the flat of one class (only root folder) within a
memory irrespective of the place (path) where the file exists really. For this reason, it becomes invalid a folder repeat and
a folder random command, and it becomes effective the repeat in a memory, one music repeat, and random in a memory
setting up a repeat setup by the SET_REPRAND command.

buffer as valid data and encoded to MP3.
[1] The command to enable the encode function turns ON.
[2] BFULLO output terminal is set to L. (The internal buffer is not FULL.)
[3] INREQI input terminal is set to H. (The microcomputer tells that this data is valid.)
When the internal buffer becomes FULL and cannot receive the data, BFULLO terminal output H. Then, data writing to
the internal buffer will stop.
When the internal buffer generates space after processing data and INREQI input terminal is set to L, BFULLO output
terminal is set to L.

19.4 Data comparison connection function
When you assume the comparison connection operation to be effective, the data newly input as the last 3 samples of
the valid data input before the comparison connection operation is set is compared.
LSI restarts the input from the following data to an internal buffer when 3 consecutive samples are corresponding
everything.
As a result, it becomes consecutive data before and after doing connected operation.
When you assume the comparison connection operation to be invalid, encode can be restarted by connecting it directly
by controlling the INREQI input.
19.5 Encode speed
The data writing speed to the memory depends on the state of the fragmentation and the usage condition in the
memory, response time from the memory.
Therefore, the encode speed that BFULLO doesn't become H for all media cannot be guaranteed.
BFULLO both becomes H while recording MP3 and WAV, and the memory that cannot be in real time recorded exists.

20. CD-ROM Decoder
When CD-ROM MODE of the system operation mode has been selected, this function is effective.
File system analysis and decoding of data are performed to 3 line serial input data from CD-ROM format.
CD-ROM ECC and the EDC function are supported.
20.1 Support File System
CD-ROM Mode1, Mode2 form1, and Mode2 form2 are supported.
The file system supports ISO9660 level 1 and 2. Remeo and Joliet extension are supported.
The folder class which can be searched support by 8 classes.
A folder name and a file name are acquirable to 48 bytes.
20.2 File system analysis
The number of entries that can be maintained in the buffer for the analysis becomes
3*(File_Number)+ 4*(Folder_Number)=1200.
It depends on the content of the composition of each CD-ROM.
It becomes a 266 files when number (Folder_Number) of folders is 100 and it becomes 366 entries in total (file or
folder).
The entry which was not able to be held to the buffer domain for analysis cannot be played after file system analysis.
The result of the file system analysis can be read by the status output.

24. Watchdog Timer
The LSI incorporates Watchdog Timer, which monitors the system hang-up and resets whenever it occurs.
After resetting hang-up, WDT (Watchdog Timer) becomes available. You can disable WDT using DIS_WDT command.
Once WDT is disabled, it cannot be enabled until reset is input.
When WDT, in the valid status, detects a hang-up within the LSI regardless of external situations (on the microcomputer),
the LSI resets the system internally.
To monitor whether the LSI is reset by WDT from the master microcomputer (external), use SET_WDT command to write
H to STATUS WDT_RFLG and monitor this status. After reset, this status is read as L. This helps you judge that WDT
has reset the LSI by reading out L when reading the status regularly after writing H using SET_WDT command.
25. IPL support to external serial FLASH ROM
Once reset, the LSI needs to download the program to a part of the internal program area from the external serial FLASH
ROM.
However, it is also possible to write in data from a microcomputer without connecting external serial FLASH ROM.
The download function from the external serial FLASH ROM enables to add and change the system functions simply by
rewriting the external serial FLASH ROM.
The program is downloaded automatically after reset. After download is completed, it shifts to CONFIG mode.
This LSI supports to serial FLASH ROM to 8 bit-Command, 24 bit-ADDRESS, and clock MIN=15MHz by minimum size
2Mbit. This LSI cannot correspond to serial FLASH ROM that doesn't correspond to Page Program because the data
writing is done with Page Program (256 bytes). This LSI supports to serial FLASH ROM to Write Status Register cycle
time MAX. = 500msec, Page Program cycle time MAX. = 500msec and Chip Erase cycle time MAX. = 180sec.
The download time of the program from serial FLASH ROM is about 0.6 sec. This time changes with contents of the
program write in serial FLASH ROM.
The LSI supports a mode which enables to write the program data written to the memory (USB or SD) to the external
serial FLASH ROM. By executing the command to enable the FLASH ROM write mode, the LSI searches in the
memory and rewrites the external serial FLASH ROM. After rewriting the FLASH ROM, you should reset the LSI.

・Play time is a period of time to make sound. Skip time is a period of time
to skip during search.
・For fast forward and rewind, a cycle of {play time (M) + skip time (N) +
error (O)} is repeated.
The error is determined by the difference between the minimum decode
unit and the rounding error between the play time and the real time
requiring to search the skip time. The error varies depending on the file
and memory structure.
・Play time is set to M[15:0]= [6th byte, 5th byte], and skip time to N[15:0]=
[8th byte, 7th byte].
The unit is msec. By default, play time is 300ms=M[15:0]= [6th
byte=x01,5th byte=x2C], and skip time is 2100ms=N[15:0]= [8th
byte=x08,7th byte=x34].
Specifying 0x0 sets the default.

26.2 Status output
The operation information, such as internal statuses, play time, folders, files and Tags, is output using an I2C interface.
The statuses shown in Table33 Status Register Map are output.
When reading status via I2C, the OFFSET position is automatically incremented after reading byte data. However, by
issuing the I2C start condition, the OFFSET position is reset to OFFSET specified by the previous command.
To read statuses, two methods are available: to specify OFFSET of the status register map and read any bytes
continuously from the OFFSET position; and to read byte data by a command without specifying the OFFSET position.
Table 34 shows the status output commands.
Byte data, when reading via I2C, is output in Little Endian format.
When read over OFFSET=0x140, OFFSET does not return to 0x00, therefore the read value turns into an unfixed
value.

According to the file structure and communication speed of an USB memory, SD memory card, this LSI might not play
back correctly.
3)
About turning on the power supply
Current rush might flow momentarily by the order of turning on the power supply and the delay in IC with two or more
power supplies, and note the capacity of the power supply coupling, the power supply, and width and drawing the GND
pattern wiring.
4)
About absolute maximum rating
When the absolute maximum rating such as the applied voltage and the ranges of the operating temperature is
exceeded, LSI might be destroyed. Please apply neither voltage nor the temperature that exceeds the absolute
maximum rating. Please execute physical measures for safety such as fuse when it is thought to exceed the absolute
maximum rating, and examine it so that the condition to exceed the absolute maximum rating is not applied to LSI.
5)
About GND Voltage
In any state of operation must be the lowest voltage about the voltage of the terminal GND. Please actually confirm the
voltage of each terminal is not a voltage that is lower than the terminal GND including excessive phenomenon.
6)
About design of overheating malfunction preventive circuit
Please design overheating malfunction preventive circuit with an enough margin in consideration of a permissible loss
in the state of using actually.
7)
About the short between terminals and the mounting by mistake
Please note the direction and the gap of position of LSI enough about LSI when you mount on the substrate. LSI might
be destroyed when mounting by mistake and energizing. Moreover, LSI might be destroyed when short-circuited by
entering of the foreign substances between the terminal and GND, between terminals, between the terminal and the
power supply of LSI.
8)
About operation in strong electromagnetic field
Use in strong electromagnetic field has the possibility of malfunctioning and evaluate it enough, please.
9)
About recording
Recording to a memory with slow access speed may require data connection operation.
Recording to all the memories cannot be guaranteed.
10)
Power off or memory disconnection under memory writing
The sudden power off or memory disconnection during recording or file write operation to a memory may break the
data in a memory.
11)
Browsing operation
With a memory with slow access speed, Browsing operation during music playing may generate skipping.
12)
CD-ROM playing
CD-ROM playing operation is premised on data being inputted so that an internal data buffer may not become empty.
When an input does not meet the deadline and internal data buffers become empty, skipping occurs.
13)
Playing time of MP3 file
The playing time when MP3 file playing may shift when fast forward playing, rewinding playing, and VBR playing.
14)
Write-in operation exceeding memory size
When memory size is exceeded, IC will stop writing to a file and will be in an error condition.
15)
Write-in operation of the file size exceeding FAT specification
When file size is exceeded, IC will stop writing to a file and will be in an error condition.

ROHM designs and manufactures its Products subject to strict quality control system. However, semiconductor
products can fail or malfunction at a certain rate. Please be sure to implement, at your own responsibilities, adequate
safety measures including but not limited to fail-safe design against the physical injury, damage to any property, which
a failure or malfunction of our Products may cause. The following are examples of safety measures:
[a] Installation of protection circuits or other protective devices to improve system safety
[b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure
3.
Our Products are designed and manufactured for use under standard conditions and not under any special or
extraordinary environments or conditions, as exemplified below. Accordingly, ROHM shall not be in any way
responsible or liable for any damages, expenses or losses arising from the use of any ROHM’s Products under any
special or extraordinary environments or conditions. If you intend to use our Products under any special or
extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of
product performance, reliability, etc, prior to use, must be necessary:
[a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents
[b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust
[c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2,
H2S, NH3, SO2, and NO2
[d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves
[e] Use of our Products in proximity to heat-producing components, plastic cords, or other flammable items
[f] Sealing or coating our Products with resin or other coating materials
[g] Use of our Products without cleaning residue of flux (even if you use no-clean type fluxes, cleaning residue of
flux is recommended); or Washing our Products by using water or water-soluble cleaning agents for cleaning
residue after soldering
[h] Use of the Products in places subject to dew condensation
4.
The Products are not subject to radiation-proof design.
5.
Please verify and confirm characteristics of the final or mounted products in using the Products.
6.
In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse. is applied,
confirmation of performance characteristics after on-board mounting is strongly recommended. Avoid applying power
exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect
product performance and reliability.
7.
De-rate Power Dissipation (Pd) depending on Ambient temperature (Ta). When used in sealed area, confirm the actual
ambient temperature.
8.
Confirm that operation temperature is within the specified range described in the product specification.
9.
ROHM shall not be in any way responsible or liable for failure induced under deviant condition from what is defined in
this document.
Precaution for Mounting / Circuit board design
1.
When a highly active halogenous (chlorine, bromine, etc.) flux is used, the residue of flux may negatively affect product
performance and reliability.
2.
In principle, the reflow soldering method must be used; if flow soldering method is preferred, please consult with the
ROHM representative in advance.
For details, please refer to ROHM Mounting specification
