ES1887 AudioDrive® Product Brief
ES1887 AudioDrive single mixed-signal chip that adds 16bit stereo sound music synthesis personal computers. equipped with embedded microprocessor, 20-voice ESFMmusic synthesizer, 16-bit stereo wave Codec, 16-bit stereo music DAC, hardware master volume control, MPU-401 UART mode serial port, dual game ports, serial port interfaces external external wavetable music synthesizer, control logic with FIFO, interface logic. There three external stereo inputs (typically line, audio, auxiliary line) mono input microphone. this embodied single chip that designed into motherboard, add-on card, integrated into other peripheral cards such voice/fax/ modem, VGA, LAN, I/O, forth. ES1887 AudioDrive® record, compress, play back voice, sound, music with built-in 6-channel symmetric mixer controls. supports full-duplex operation simultaneous record playback using channels. these channels supports bidirectional, 8-bit programmed data transfers other supports 8-bit 16-bit playback. MPU-401 hardware interfacing external MIDI serial port. ES1887 music allows external wavetable synthesizer through ES1887's third serial port. speaker volume controlled software. software address selection modes allow BIOS Plug Play configuration. dual game ports support joysticks both having resistor value settings pushbutton switches. serial interface allows external take over resources. Advanced power management features include suspend/resume from disk host-independent, self-timed power-down automatic wake-up. ES1887 backward compatible compatible with ES1888. ES1887 AudioDrive® available industry-standard 100pin Plastic Quad Flat Pack (PQFP) package.
