Yamaha YMF715 Audio Chip
YMF715-S (OPL3-SA3) is a single audio chip that integrates OPL3 and its DAC, 16 bit Sigma-
delta CODEC, MPU401 MIDI interface, joystick with timer, 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. 16 bit 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.
