OPL3-SA3
OPL3 Single-chip Audio System 3
OUTLINE
YMF715E-S (OPL3-SA3) is a single audio chip that integrates OPL3 and its DAC, 16bit Sigma-delta
CODEC, MPU401 MIDI interface, joystick port, and a 3D enhanced controller including all the analog
components which is suitable for multi-media application. This LSI is fully compliant with Plug and Play
ISA 1.0a, and supports all the necessary features, i.e. 16bit address decode, more IRQs and DMAs in
compliance with PC’98. This LSI also supports the expandability, i.e. Zoomed Video, Modem and CD-
ROM interface in a Plug and Play manner, and power management (power down, power save, partial
power down, and suspend/resume) that is indispensable with power-conscious application.
FEATURES
• Built-in OPL3 (FM-synthesizer)
• Supports Sound Blaster Game compatibility
• Supports Windows Sound System compatibility
• Supports Plug & Play ISA 1.0a compatibility
• Full Duplex operation
• Built-in MPU401 Compatible MIDI I/O port
• Built-in Joystick port
• CODEC’s DAC : S/N=82dB (min.)
• Built-in the 3D enhanced controller including all the analog components
• Supports multi-purpose pin function
(Support 16-bit address decode, DAC interface for OPL4-ML/ML2, Zoomed Video port, EEPROM
interface, MODEM interface, IDE CD-ROM interface)
• Hardware and software master volume control
• Supports monaural input
• 24 mA TTL bus drive capability
• Supports Power Management(power down, power save, partial power down, and suspend/resume)
• +5V/ +3.3V power supply for digital, 5V power supply for analog.
• 100 pin SQFP package (YMF715E-S)

1. 16bit Address Decode
The signal AEN* generated by decoding SA15-12 and AEN needs to be connected to the
AEN of OPL3-SA3.
2. ZV Port and OPL4-ML/ML2 I/F
ZV port is supported by using the internal DAC of OPL3-SA3 that is originally dedicated for
the use of internal OPL3.
(i) either OPL4-ML/ML2 or ZV port is active at a time and simultaneous use is not
possible.
(ii) which function the internal DAC is used for is determined by the SA3 Control
register, index 02h, VZE bit.
