Features
FM synthesizer functions
■ 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.
YMU759B 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
fromtwo kinds.)
■ Number of voices simultaneously generated
YMU759B is equipped with 32 operators.
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.
■ Compatible with stereophonic sound generation.
■ Volume control
Channel volume, master volume, expression, and pan pot control in individual channels.
■ Sequencer is built in.
■ Can interpret Mobile Multimedia Format directly.
■ Equipped with four systems of 96 FIFOs for sequence data.
■ Supports direct access that directly controls FM synthesizer.
■ Supports key control with half an octave higher and lower.
ADPCM reproduction function
■ Equipped with ADPCM decoder with 4 bits, 1 channel.
■ Supports two kinds of sampling frequency, 4 kHz and 8 kHz.
■ Sequencer is built in.
■ Equipped with 348 byte FIFO for ADPCM data and 32 byte FIFO for sequence data.
■ Supports direct access that directly controls ADPCM section.
Speaker amplifier and equalizer circuit
■ Output of speaker amplifier: 550 mW when SPVDD=3.6 V, or 400 mW when SPVDD=3.0 V.
■ Balanced input speaker amplifier provides low ripple
■ Built-in equalizer circuit corrects the difference of frequency response among the speakers and forms of bodies.
Interface
■ 4 wire serial interface or 12 wire parallel interface can be selected.
Others
■ PLL is built-in to support master clock input in 2 MHz to 20 MHz range.
■ Provided with a circuit for controlling on/off of LEDs and vibrator. These can be operated synchronous with
the play data.
■ Provided with a stereophonic analog output terminal for headphone.
■ 16 bit stereophonic D/A converter is built in.
■ Supports power down mode. (Typical current: 1 A or less)
Power supply voltage
■ The power supply includes two power supply sub-systems, analog power supply devoted to speaker amplifier
and power supply for other sections.
■ 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
■ The plating of pins is lead-free. (YMU759B-QZ)
