GENERAL DESCRIPTION
FEBRUARY 2000
IS22C040 high-quality voice synthesizer with capacity seconds. proprietary ADPCM algorithm used. audio message stored 1024Kbit 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.
