Features for YMU759B-QZE2

The electronic component YMU759B-QZE2 is a component of the YMU759 series. 


Following are features for this parts:

 FM synthesizer functions

1.       Tones

    FM synthesizer is capable of creating countless tones theoretically.

    When synthesizing tones, it is necessary to designate the number of operators to be used for the synthesis.

    Increasing the number of operators allows synthesis of tones that are more intricate and closer to those generated by natural musical instruments.

    YMU759 supports synthesis of tones of two types including 2-operator tones and 4-operator tones. Because operator's wave shape can be chosen from eight kinds, the quality of sound improves more remarkably than 2 operator sound of the MA-1 series. (A MA-1 series can choose operator wave shape from two kinds.)

2.       Number of voices simultaneously generated

YMU759 is equipped with 32 operators.

    The number of voices simultaneously generated varies depending on how many 2-operator tones and 4-operator tones are used.

When only 2-operator tones are used: up to 16 voices can be generated simultaneously.

When only 4-operator tones are used: up to 8 voices can be generated simultaneously.

3.       Compatible with stereophonic sound generation.

4.       Volume control

    Channel volume, master volume, expression, and pan pot control in individual channels

5.       Sequencer is built in.

6.       Can interpret Mobile Multimedia Format directly.

7.       Equipped with four systems of 96 FIFOs for sequence data

8.       Supports direct access that directly controls FM synthesizer.

9.       Supports key control with half an octave higher and lower.

        ADPCM reproduction function

1.       Equipped with ADPCM decoder with 4 bits, 1 channel

2.       Supports two kinds of sampling frequency, 4 kHz and 8 kHz.

3.       Sequencer is built in.

4.       Equipped with 348 byte FIFO for ADPCM data and 32 byte FIFO for sequence data

5.       Supports direct access that directly controls ADPCM section.

        Speaker amplifier and equalizer circuit

1.       Output of speaker amplifier: 550 mW when SPVDD=3.6 V, or 400 mW when SPVDD=3.0 V

2.       Balanced input speaker amplifier provides low ripple

3.       Built-in equalizer circuit corrects the difference of frequency response among the speakers and forms of bodies.

        Interface

1.       4 wire serial interface or 12 wire parallel interface can be selected.

      

 Others

1.       PLL is built-in to support master clock input in 2 MHz to 20 MHz range.

2.       Provided with a circuit for controlling on/off of LEDs and vibrator. These can be operated synchronous with the play data.

3.       Provided with a stereophonic analog output terminal for headphone

4.       16 bit stereophonic D/A converter is built in.

5.       Supports power down mode. (Typical current: 1 μA or less)

        Power supply voltage

1.       The power supply includes two power supply sub-systems, analog power supply devoted to speaker amplifier and power supply for other sections.

2.       The power supply for the speaker amplifier (SPVDD) supplies voltages in the range 2.7 V ~ 4.5 V (Typ 3.6 V), and other power supplies (VDD) voltages in the range 2.7 V ~ 3.3 V (Typ 3.0 V).

        32-pin plastic QFN.
