Eigenschaften:

・BU94603KV is AAC+WMA+MP3 decoder IC in which a USB host I/F, SD memory card I/F,
    audio DAC and system control functions are built. Using a KEY or I²C interface
    command, the IC reads out a MP3 file written to a memory device having a USB I/F
    or a SD memory card. All the operations required before the data can be output to
    audio devices are incorporated into one chip.
・BU94603KV supports STAND ALONE MODE which is enabled by commands entered
    from the keyboard (hereinafter referred to as MODE1), AUTO SLAVE MODE which
    is enabled by commands entered from the master microcomputer, same as those
    entered from the keyboard, via the built-in I²C interface (hereinafter referred to as
    MODE2) and MANUAL SLAVE MODE which can send the memory device
    information to the master microcomputer via the I²C interface and completely
    control sequences such as a play sequence by the master microcomputer
    (hereinafter referred to as MODE3).
・BU94603KV supports fast forward playing and fast backward playing with music.
・BU94603KV outputs folder names, file names, ID3TAG (V1.0, V1.1 V2.2 V2.3 and V2.4)
    information and WMA-TAG information and AAC-TAG(iTunes Meta-data)
    information via the I²C interface. This function is enabled only in MODE 2 and
    MODE 3.
・BU94603KV supports audio line output, audio serial three-line (I2S) output and digital
    audio interface (SPDIF) output.
・Reading a specified file data is possible from USB memory. *Only a file that exists in root
    folder corresponds.
