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. Standard Code Line Up Times to Times to 1 2 3 4 5 6 Code# 002 010 017 018 020 021 Title Ho,Ho,Ho, Merry X'mas!!

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.
