YMU762 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 built in ROM and arbitrary ADPCM/PCM voices from sequencer by the download of the melody with voices etc.. MA-3 has a built-in hardware sequencer that helps to realize plex play without heavily loading the host CPU. The device also has a built-in circuit for controlling vibrators and LEDs synchronizing with play of music. Features MA-3 has features as described below. - - - - - - - - - - - - - - - - Simultaneous generation of up to 40 tones: FM + Wave Table stereophonic hybrid synthesizer. Polyphonic synthesizer specification. Has built-in default voices for FM and Wave Table synthesizers in the ROM, and the voices can be downloaded to RAM. Fundamental waveforms for FM and algorithm are improved pared with YMU759 (MA-2), and voice parameters of detune etc. are added. Stream replay with ADPCM / PCM (shared use of Wave Table section). Software interrupt mechanism for external synchronization. Equipped with 8 bit parallel I/F for control from CPU. Equipped with speaker amplifier and equalizer circuit. Equipped with vibration control circuit, and LED lighting control circuit. Has built-in PLL to support inputting of master clock up to 20 MHz. Contains a 16-bit stereophonic D/A converter. Equipped with a stereophonic output terminal for headphone. Supports power down mode. Digital power supply: 2.7V to 3.3V (Typ 3.0V) Analog power supply: 2.7V to 4.5V (Typ 3.6V) 32-pin QFN plastic package The contents of this booklet are target specifications and they are subject to change without a prior notice.
