YMF721  
OPL4-ML2  
FM + Wavetable Synthesizer LSI  
OVERVIEW  
YMF721 (OPL4-ML2) is a high quality and low cost Wavetable synthesizer LSI. YMF721 (OPL4-ML2)  
integrates an OPL3 (FM synthesizer), General MIDI processor and 1 Mbyte Wavetable sample ROM into one  
chip, and complies with General MIDI (GM) system level 1. Thus, it is best suited to multimedia applications,  
sound cards, MIDI synthesis modules and other sound applications.  
Since this LSI outputs stereophonic 16 bit digital signal (fs = 44.1 kHz), it can be connected directly with  
YMF701B, 711 or 715 (OPL3-SA, SA2 or SA3) or with YAC516(DAC16-L).  
Operating voltage, 3.3 V, allows this LSI to be controlled with notebook personal computers.  
Power management functions (power down and suspend/resume functions) of OPL4-ML2 contribute to low  
power consumption of personal computers into which this product is built-in.  
FEATURES  
• The Wavetable synthesizer of this LSI is able to generate up to 24 types of sounds simultaneously.  
• Has an interface that makes this LSI compatible with MPU-401 UART mode.  
• Has an OPL3 (FM synthesizer) for AdLib/Sound Blaster applications.  
• Has a 1 Mbyte built-in Wavetable sample ROM.  
• Complies with GM system Level 1. (Thus, it is compatible with DOS applications that support MPU-401.)  
• MIDI signal can be transmitted either through serial input or parallel input.  
• FM synthesizer and Wavetable synthesizer of this LSI can generate their sound at the same time.  
• FM synthesizer is register-compatible with OPL3.  
• All registers are readable.  
• Power management functions included power down and suspend/resume can be supported.  
• Frequency of master clock signal is 33.8688 MHz.  
• Pin compatible with YMF704C-S (100 pin SQPF)  
• Voltage of power supply can be 5.0 V or 3.3 V.  
• Silicone gate CMOS process  
• 100-pin SQFP (YMF721-S).  
GENERAL MIDI logo is a trademark of Association of Musical Electronics Industry (AMEI), and  
indicates GM system level 1 Compliant.
