Maximum Playable Files per Folder FAT12 FAT16 FAT32 Root folder Sub folder 512 512 65535 65534 65534 65534 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. www.rohm.com © 2012 ROHM Co., Ltd. All rights reserved.

[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.

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. www.rohm.com © 2012 ROHM Co., Ltd. All rights reserved.

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. www.rohm.com © 2012 ROHM Co., Ltd. All rights reserved.

Table 18. Resume information register structure The Status number NAME Contents OFFSET of bytes 0x38-0x61 42 Resume information data This data shows the information on the file being played and on the play position. 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. www.rohm.com © 2012 ROHM Co., Ltd. All rights reserved.

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. The file information status register structure which can be read by the file browsing function in a memory is shown in Table 22. Table 22.

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. www.rohm.com © 2012 ROHM Co., Ltd.

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. www.rohm.com © 2012 ROHM Co., Ltd. All rights reserved.

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. www.rohm.com © 2012 ROHM Co., Ltd. All rights reserved.

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. Table 33.

After completely starting up 3.3V system power supply, afterwards, please make the terminal RESETX High level after 100us after the oscillation of the system clock is steady. Moreover, please make the terminal RESETX Low level during 100us or more when resetting it while operating. 2) About compatibility in USB memory device and SD memory card 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. 16) About WMA Windows Media Audio is the music compression technology which Microsoft Corp. developed. Windows Media is the registered trademark of U.S. Microsoft Corporation in the U.S., and other countries. 17) About I2C format I/F Although this LSI has adopted the I 2C format, the level shifter circuit is not built in. For this reason, level shifter is needed for connection with the device besides the range of operating power supply voltage of this LSI. 18) About " Made for iPod / iPhone / iPad License " For using of BU94607AKV / BU94705AKV, It is necessary to become a licensee of Apple Inc. regarding "Made for iPod/iPhone/iPad License" Status of this document The Japanese version of this document is the formal specification.

Our Products are designed and manufactured for application in ordinary electronic equipment (such as AV equipment, OA equipment, telecommunication equipment, home electronic appliances, amusement equipment, etc.). If you intend to use our Products in devices requiring extremely high reliability (such as medical equipment (Note 1), transport equipment, traffic equipment, aircraft/spacecraft, nuclear power controllers, fuel controllers, car equipment including car accessories, safety devices, etc.) and whose malfunction or failure may cause loss of human life, bodily injury or serious damage to property (“Specific Applications”), please consult with the ROHM sales representative in advance. Unless otherwise agreed in writing by ROHM in advance, ROHM shall not be in any way responsible or liable for any damages, expenses or losses incurred by you or third parties arising from the use of any ROHM’s Products for Specific Applications. (Note1) Medical Equipment Classification of the Specific Applications JAPAN USA EU CHINA CLASSⅢ CLASSⅡb CLASSⅢ CLASSⅢ CLASSⅣ CLASSⅢ 2. 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 (Exclude cases where no-clean type fluxes is used. However, recommend sufficiently about the residue.) ; 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 depending on ambient temperature. When used in sealed area, confirm that it is the use in the range that does not exceed the maximum junction 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 on a surface-mount products, the flow soldering method must be used on a through hole mount products. If the flow soldering method is preferred on a surface-mount products, please consult with the ROHM representative in advance. For details, please refer to ROHM Mounting specification Notice-PGA-E © 2015 ROHM Co., Ltd. All rights reserved. Rev.004 Precautions Regarding Application Examples and External Circuits 1.
