General Description
The MSS0271 is a single-chip CMOS LSI demands minimal external components and memorizes voice up to 2.88
seconds (at 6 KHz S.R.) using the MOSEL qualified coding method (MPCM-4). The chip contains most of the
necessary circuit like oscillator, PLA, D/A converter, buzzer buffer, control and timing logic. Therefore, it can apply
to various voice systems with minimum external parts. Customer speech data will be edited and programmed into
PLA by changing one mask during the device fabrication.

Preliminary
Signals
SP+ and SPThey are tristate during standby.
They are not at standby current when the data is in the
middle.
These two pins can drive buzzer or speaker, 8 ohm or
16 ohm, directly. The speaker used should have its
band width (BW) at the center of your sound frequency
domain or you are unable to play your sound good by
this speaker.
For instance, you have your sound spans over
frequency from 100 Hz through 10 KHz. A speaker with
BW meets requirement will play this sound good. A
speaker with BW narrower than requirement (either has
higher low-cut or lower high-cutoff) will distort the sound
very much because that most of the energy of the
playback sound is unable to be played by this speaker.
This pair has zero output when sound data is zero. This
pair has full output when sound data is the highest.
This pair has half of full output when sound is silence at
middle data value. This pair has half of full output when
playing sound at appended memory-less mute.
The output depends on Vdd bias very much.
Herein zero output does not mean zero potential,
neither ground.
It is recommended to select voltage source carefully
and do not supply this chip with a voltage potential
source in poor flatness or in poor drive capability.
What the poor source means either its potential drops
as the load varies or its potential drops as its capacity
exhausted.
The speaker characeristics and housing impacts the
loudness very much.
TG
This is a high true activating signal input pin.
internal pull low R TG is built in.
There is no schmit trigger circuit implemented.
An
IN0 and IN1
They should be bonded to ground both regularly.
While abnormal lot (pitch shifted) is encountered,
special bonding could be done herein.
LB
This pin could be optionally masked as either high true
Busy signal or LED flasher which is turned on in sink
way by I LED. Refers to paragrahps "Mask option" and
"terms". Up to 3 types of LED flasher could be chosen.
Terms
Audio
Audio means the signal from the pin pair SP+ and SP-.
Due to a sophisticated architecture, there demands no
ramp up (or ramp down) to eliminate the pop noise at
the sound starting and ending.
MSS0271
Ramp up and Ramp down
See the explanation of Audio.
Sample Rate
All the AC parameters depend on sample rate except
three - t PUD, t P and t R. The numbers mentioned in this
data sheet are based on 6 KHz sample rate if not
specified. Higher SR has quicker LED flasher, quicker
response. Lower SR has slower LED flasher, slower
response.
Retriggerable TG
Retriggerable TG means the sound played could be
terminated immediately while further TG activated and
play the sound from the very beginning.
Holdable and retriggerable
This combination allows user controlling both the output
and the input. Its output is holdable and the input could
retrigger the former. This is an exquisite feature. It is not
provided on this single trigger voice chip.
Fix flash LED
Fix 3 Hz flash means this pin turns LED lamp on for T
LED3 and then turns it off for T LED3 alternately. Fix 6 Hz
flash means quicker, it turns on T LED6 and then turns off
T LED6.
The 3 Hz as well as 6 Hz is sample rate dependent.
When repeatedly playing a word, interesting LED flash
may happen in concatenation. The word length may not
be the multiples of T LED3 (or T LED6), a new flash cycle
will start before the last flash cycle terminates.
Dymanic Flash LED
The LED turns on whenever the sound amplitude (the
current from SPs) is over a certain threshold potential (I
LEDT). The sound potential could be measured in data
value as an alternative.
Debounce time
Either Fast or Slow debounce are provided by mask
options. The Fast debounce acknowledges very short
trigger. So, the sound will play "sensitively". User should
be very carefully to choose trigger switch while "Fast
debounce" is specified.
Application Notes
Speaker
The typical application speaker is 8 ohm, 1/4 watt. Refers
to above paragraph SP+ and SP- for more description on
required speaker.
Buzzer
The recommended resonant frequency should be 1 KHz
to get the best sound response. The response BW also
should be fit to the required sound band width. Refer to
above paragraph SP+ and SP- for more description.

Cascading
Cascading chips to have longer duration is possible by
special wiring but not recommended.
Choice of sample rate
The sample rate should be chosen before chip
manufactured. Two sample rates are provided on
S0271 - either 6200 KHz or 8400 KHz. User is able
to select them on the attached PRF (product request
form).
Paralleling
Paralleling chips to have more triggers is possible by
special wiring but not recommended.
Rosc
No external Rosc is required.
Bulk Capacitor
A bulk capacitor 0.1uF across the Vdd to Vss is
demanded when using 4.5V (or higher) working voltage.
At every working voltage, the value of bulk capacitor
should be less than or equal to 0.47uF.
Audio band amplifier transistor
No amplifier transistor is demanded.
PCB layout
To minimize the interference, the route from trigger
switch to chip should be as short as possible. The
route of trigger signal is recommended to as far away
as possible to speaker output.
Bonding change while Rosc shifts
MVI S0271 provides reliable built-in Rosc by advance
technology. In case Rosc is shilfted (pitch shifted), the
bonding change is able to bias Rosc into nominal value.
The bonding changes are described on page 11/12.
While the pitch shift encountered even it is rarely, the
part number will have a postfix letter-capital "Z" while
the lot number will have the two letter extension
simultaneously. The two-letter extension could be "LH",
"HL" or "HH". This two-letter extension tells how the
bonding should be done which are described on page
11/12.
CDS as trigger
to be defined.
Power On play
This chip provides power on play function. User
should be noted that the time parameter T PUD is
zero. To connect the trigger to Vdd, the sound will
be played whenever power is turned on.

Bonding to Offset the Shifted Pitch
Below three special bonding means are used to offset the shifted pitch (frequency) and let it perform normally.
This happens only for those chip lots have their part number with postfix letter "Z". To not use these special
bonding means on normal part is strongly recommended.
Of course, the copper route may have different layout on PCB (printed circuit board). It should be decided by
user himself. Below shows only what we recommended, not restricted.
