YMU765 is a synthesizer LSI for mobile phones that realize advanced game sounds of Java application program etc.
This LSI has a built-in speaker amplifier, and thus, is an ideal device for outputting sounds that are used by mobile
phones in addition to game sounds and ringing melodies that are replayed by a synthesizer.
The synthesizer section adopts the “Stereophonic Hybrid Synthesizer System” which is given advantages of both FM
synthesizers and Wave Table synthesizers to allow simultaneous generation of up to 32 FM voices and 32 Wave Table
voices. Furthermore, the stream playback function, the voice synthesis function by HV (Humanoid Voice) synthesizer
(*), and the time-variant low pass filter function by AL (Analog Lite) synthesizer have also on board.
Since FM synthesizer is able to present countless voices by specifying parameters with only several tens of bytes,
memory capacity and communication band can be saved, and thus, the device exhibits the features in operating
environment of mobile phones such as allowing distribution of arbitrary melodies with voices.
On the other hand, Wave Table synthesizer can pronounce the voice built in ROM and arbitrary ADPCM/PCM voices
from sequencer by the download of the melody with voices etc..
YMU765 has a built-in hardware sequencer that helps to realize a complex play without heavily loading the host CPU.
In addition, it is possible to create more highly efficient applications by the voice synthesis function (*) and the function
of time-variant low pass filter. Moreover, the device also has a built-in circuit for controlling vibrators and LEDs
synchronizing with play of music.
(*) HV synthesizer function only responds to Japanese and Korean language at present.
Features
Built-in the hybrid synthesizer, and possible to generate 64 tones simultaneously as maximum.
Voice synthesis voice function by HV (Humanoid Voice) synthesizer is on board.
(*) HV synthesizer function only responds to Japanese and Korean language at present.
The time fluctuation low pass filter function by AL (Analog Lite) synthesizer is on board.
Stream replay with ADPCM / PCM is possible.
Has built-in default voices for FM and Wave Table synthesizers in the ROM, and the voices can be downloaded to
RAM.
Equipped with speaker amplifier and equalizer circuit.
Equipped with a stereophonic output terminal for headphone.
Equipped with vibration control circuit, and LED lighting control circuit.
Has built-in PLL and inputting of master clock up to 20 MHz is possible and compiles with the TCXO (Temperature
Compensated Crystal Oscillator).
Contains a 16-bit stereophonic D/A converter.
Has power down mode.
