Caution
(1) Power on Reset
Please keep the terminal RESETX at the Low level when the power supply starts. 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) Power off or memory disconnection under memory writing
The sudden power off or memory disconnection during file write operation to a memory may break the data in a memory.
(10) Browsing operation
With a memory with slow access speed, Browsing operation during music playing may generate skipping.
(11) 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.
(12) Playing time of MP3 file
The playing time of an MP3 file may shift when fast forward playing, rewinding playing, and VBR playing.
(13) 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.
(14) 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.
(15) 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.
(16) About I2C format I/F
Although this LSI has adopted the I2C 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.
