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- chann el spe ec h and instrum ent pla ybac k. T he m icro-contr oller inc ludes a powerf ul 8-
bit RISC CPU to handle most of the speech/melody functions, an 8K word program ROM, and a
voice RO M t hat ex ten ds up to 2 M bytes. T here are t wo s peec h c ha nne ls an d f our m e lod y channe ls
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 r eal instrum ent waveform s to obtain good qual ity audio m elody. The EM600 00 offers one
8-bit i nput p or t and o ne 8- b it I /O port with interna l pul l-l o w/ wak e-up f unc ti ons f or user ’s ap pl ic ati ons.
In addition, up to three general I/O ports are provided. By programming the micro-controller,
applicat ions such as section c ombination, tr igger m ode, output contr ol, keyboar d matr ix, 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).
