General Description

The ES1878 AudioDrive® is a mixed-signal single-chip solution that adds 16-bit stereo sound and FM music synthesis to notebook puters.

The ES1878 includes an embedded microprocessor, a 20-voice ESFM™ music synthesizer, 16-bit stereo ADC and DACs, optional ISA Plug and Play (PnP) support, hardware master volume control, DMA control logic with FIFO, ISA bus interface logic, general-purpose I/O, and digital dual game port.

The ES1878 also incorporates three serial ports which allow interfacing with external DSP, wavetable, and MIDI (MPU401 UART Mode patible).

Key Features

  • Subtractive Decode and Positive Decode Modes. The MPU-401 serial port is for interfacing with an external MIDI device. The digital dual game port supports two joysticks with hardware timing which uses less CPU overhead and improves system performance. A DSP serial interface in the ES1878 allows an external DSP to take over ADC or DAC resources. A wavetable serial port allows the ES1878 to interface with either the ES689 or ES690 wavetables. I/O address, DMA, and interrupt selection can be contro.
