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.
Features
Operating voltage: 2.4 ~ 5.5V.
8-bit RISC CPU.
Two general-purpose timers and two speech timers with interrupts.
8K word program ROM access.
Total of six channels--the 2 speech and 4 melody channels can be played simultaneously.
Wide-range of speech sampling rates--4KHz to 20KHz (program controlled).
Speech/voice algorithm implemented by software--PCM, ASPCM, ADPCM.
On chip Voice ROM will extend up to 2M Bytes.
Uses real instrument waveforms for good quality audio melody.
Built-in 8-bit by 8-bit hardware multiplier with 16-bit result.
One 8-bit input port and one 8-bit I/O port with pull-low/wake-up functions.
Provides additional general-purpose I/O ports (up to 3 ports).
Provides crystal oscillation or internal oscillator (by connecting a resistor).
Two 8-bit current DAC outputs.
Built-in watchdog timer (WDT).
