YMU769 Datasheet | Yamaha

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 stored in ROM, and in addition it can handle arbitrary ADPCM/PCM voices by sequencer. Furthermore, the Stream Playback function, and the time-variant low pass filter function by AL (Analog Lite) Synthesizer are equipped. YMU769 has two-channel virtual speaker image functions based on DVX technology, so that natural stereo sounds can be realized even in an environment such as two adjacent speakers on a small body like mobile phones. Integrated stereo speaker amplifiers make external ponents unnecessary and consequently it saves space. In addition, YMU769 has a built-in circuit to control an LED or a vibrator synchronously to music, and has a power down mode for saving supply current to a minimum. - Features ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ ¾ Simultaneous generation up to 64 tones by stereophonic hybrid synthesizer. Equipped with time-variant low pass filter function by AL (Analog Lite) synthesizer. 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 SRAM. Has built-in SD (Stereo Dipole) function by DVX technology. Equipped with speaker amplifier and equalizer circuit. Equipped with a stereophonic output pin for headphone. Equipped with vibration control circuit, and LED lighting control circuit.
