FEATURES
Voice length sampling seconds sampling seconds Silence compression save memory Eight trigger pins, sections play-all sequential play-all debounce time suitable interrupt stops playback once stop pulse generated playback BUSY signal control LEDs flash interval 3.0V single power supply operation standby current Auto-power down Built-in oscillator, converter, EPROM ADPCM data compression Optional noise elimination function COUT drives speaker with transistor Development tools support VOUT1 VOUT2 drives buzzer directly Sampling rate determined external resistor Holdable unholdable triggering option Industrial temperature available
IS22C040 high-quality voice synthesizer with capacity seconds. proprietary ADPCM algorithm used. audio message stored 1024-Kbit on-chip EPROM. IS22C040 eliminates need complicated circuitry voice playback (Figure still achieves high voice quality. Sounds such human speech, animal sounds, musical sounds, even special sound effects synthesized. Devices cascaded achieve longer voice duration (Figure devices configured parallel (Figure order achieve signal mixing without external mixer allowing speeches mixed with background music synthesis from different chips. instant programming nature IS22C040 allows very short production turnaround time. There charges that usually required with conventional voice ROMs. Users apply voice synthesis function additional feature their products even when production volume relatively small. also ideal trial engineering prototyping. result, initial investment minimal risk product development phase reduced. IS22C040 provides wide voltage operating range from 3.0V 6.0V. pair output pins, VOUT1 VOUT2 provide direct drive buzzer (Figure Voice quality from buzzer comparable speaker output power consumption much lower. current output pin, COUT, enables device drive speaker with cost transistor. complex filtering amplifier circuit needed. automatic ramp up/down function eliminates undesired noise playback. sections accessible through trigger programmed playback sections sequentially from section interrupt (IRP) stop pulse (STP) BUSY signals provide handshaking with microprocessors other IS22C040 devices. trigger pins give debounce time ideal applications Figure drivers available, flashing approximately intervals (Figure internal voltage compensation oscillator requires only external resistor. Different sampling frequencies determined external oscillator resistor value.

Programmable Options
IS22C040 provides different control functions user specified applications. They include: Non-sequential Sequential Play-all Unholdable Holdable trigger STOP BUSY signal selection Automatic ramp-up/ramp-down ramp-up/ramp-down
Silence Compression
particular sound sequence includes periods silence, IS22C040 will automatically compress silence save memory space. This compression will affect playback sound sequence.
