Preliminary
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'96. 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.
