EM60000

STEREO FOUR CHANNEL 8-BIT BASED SOUND PROCESSOR

General Description

EM60000 series is an 8-bit micro-controller based sound processor IC with an audio function that

delivers multi-channel speech and instrument playback. The micro-controller includes a powerful 8-

bit RISC CPU to handle most of the speech/melody functions, an 8K word program ROM, and a

voice ROM that extends up to 2M bytes. There are two speech channels and four melody channels

that can be played back simultaneously. The speech synthesis is implemented by software with

support for a wide range of sampling rates and different volume levels. The micro-controller also

provides real instrument waveforms to obtain good quality audio melody. The EM60000 offers one

8-bit input port and one 8-bit I/O port with internal pull-low/wake-up functions for user’s applications.

In addition, up to three general I/O ports are provided. By programming the micro-controller,

applications such as section combination, trigger mode, output control, keyboard matrix, and other

logic functions can be easily implemented. Together, all these powerful features will inspire the

user to realize a wide variety of ideas.
