ES1878 AudioDrive® Product Brief
ES1878 AudioDrive mixed-signal single-chip solution that adds 16-bit stereo sound music synthesis notebook computers. ES1878 includes embedded microprocessor, 20-voice ESFMmusic synthesizer, 16-bit stereo ADCs DACs, 16-bit stereo music DAC, optional Plug Play (PnP) support, hardware master volume control, control logic with FIFO, interface logic, general-purpose I/O, digital dual game port. ES1878 also incorporates three serial ports which allow interfacing with external DSP, wavetable, MIDI (MPU-401 UART mode compatible). addition, ES1878 offers Zoom Video interface support optional ES978 Expansion Audio Mixer docking stations. four-wire expansion analog two-wire serial control connect ES1878 with ES978, allowing ES1878 engage docking station's audio resources when docked. ES1878 AudioDrive® record, compress, play back voice, sound, music with built-in mixer controls. Using high-performance channels, ES1878 supports full-duplex operation simultaneous record playback. ESFMsynthesizer extended capabilities within native mode operation providing superior sound power down capabilities. ES1878 register compatible with Yamaha's OPL3FM synthesizer. ES1878 AudioDrive® supports optional Plug Play with configuration logical devices: configuration device, audio plus ESFMTM, game port, MPU-401. MPU-401 serial port interfacing with external MIDI device. digital dual game port supports joysticks with hardware timing. serial interface ES1878 allows external take over resources. wavetable serial port allows ES1878 interface with either ES689 ES690 wavetables. address, DMA, interrupt selection controlled through system software Plug Play. Advanced Power Management (APM) features include suspend resume from disk. ES1878 available industry-standard 100-pin Small Quad Flat Pack (SQFP) package.
