EM61000

8-Channel Wave-Table Music Synthesizer

1. GENERAL DESCRIPTION

EM61000 series is an 8-bit micro-controller based music processor IC with audio

function that delivers 8 channels instrument playback. The micro-controller

includes a powerful 8-bit RISC CPU to handle most of the music functions, an 8K

words program ROM, and a voice ROM that extends up to 512K bytes. There are

eight

melody

channels

that

can

be

played

back

simultaneously.

The

micro-controller provides real instrument waveforms to obtain good quality audio

melody. The EM61000 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.
