General Description

The MSU30x2 is a monolithic talking microcomputer that can memorize voice up to 60/90/120 seconds
using MOSEL qualified coding method(MPCM). It's an integration of traditional 4-bit microcomputer and
voice chip with minimal external components. LCD driver and miscellaneous interface are provided
for versatile applications. With more than bit 10K ROM/RAM inside, this chip meets every intelligent
novelty. Customer requested function and voice data will be built in by changing masks during fabrication.

Cout
Cout is tristate during standby.
Cout has zero current output when sound data is
zero. Cout has full current output when sound
data is the highest. Cout has half of full current
output when sound is silence at middle data value.
Cout has half of full current output when playing
sound at appended memory-less mute.
The bypass Cout Resistor is used to bypass the
audio output current from Cout. This bypassing
extra current to ground gives a way to prevent the
saturation of audio waveform amplified by
transistor. This Resistance is 470 ohm typically. It
always is not very small. Or user can let it open if
the transistor has a fair beta value.
A transistor with beta value 150 is sufficient for
typical applications. Larger beta value get larger
sound but may have the amplified waveform
saturated.

Common Plate Usage

Vout1, Vout2
They are tristate during standby state.
These two pins can drive buzzer directly. The piezo
buzzer used should have its resonant frequency at
the center of your sound frequency domain or you are
unable to play you sound good by this buzzer.
For instance, you have your sound spans over
frequency from 100 Hz through 1 KHz. A buzzer
with resonant frequency at 300 Hz will play this sound
good. A buzzer with resonant frequency at 1 KHz
will distort the sound very much because that most of
the energy of the playback sound is unable to be
played by this buzzer.
When using precise sample rate, these Vout 1 & 2 do
not work.
