FEATURES  
GENERALDESCRIPTION  
• Minimum 20 second voice length at 6 KHz  
• Versatile features for playback  
IS22C022 is a high quality voice synthesizer capable of  
varyingplaybackduration. AproprietaryADPCMalgorithm  
is used. The audio message is stored in a 512K bits  
on-chip EPROM which can store up to 20 seconds of  
voice data at 6 KHz sample rate.  
• Combination of voice building blocks  
extends the duration of playback  
• Voice data re-use saves memory space  
• Four trigger pins, S1 to S4 for eight groups  
• SBT for sequential play-all or random play  
TheIS22C022eliminatestheneedofcomplicatedcircuitry  
in voice playback but still achieves high voice quality.  
Sounds such as human speech, animal sounds, musical  
soundsandevenspecialsoundeffectscanbesynthesized.  
Versatilecombinationsinsectionsachievelongerplayback  
duration. In addition, devices can be cascaded to achieve  
longer voice duration. Two devices can be configured in  
parallel in order to achieve signal mixing without an  
external mixer in which speech can be mixed with  
background music each from one of two different chips.  
• Holdable and unholdable, edge and level  
triggering option  
• 15 ms debounce time suitable for CDS  
• IRP interrupt pin for master reset  
• Three programmable output pins for STP Stop  
Pulse, BUSY Signal, and LED  
The IS22C022 provides wide operating voltage range  
from 2.4V to 6.0V. PWM digital amplifier output pins,  
VOUT1 and VOUT2 provides direct drive to buzzer or  
speaker.  
• Built-in oscillator with variable sample rate  
• Single external resistor to determine sample rate  
• Built-in D/A converter, EPROM  
A current output pin, COUT, enables the device to drive a  
speaker through a low cost NPN transistor. No complex  
filtering or amplifier circuit is needed. An automatic  
ramp-down function eliminates undesired noise at the end  
of playback.  
• ADPCM data compression provides high sound  
quality  
• Optional pop noise elimination function  
• COUT pin drives speaker with a transistor  
Group of sections  
The voice data memory area of the IS22C022 can be  
subdivided into 126 sections. Any combination of these  
sections will form an individual group for data playback. A  
maximum of eight groups are available with activation  
controlled by S1 to S4 pins. The SBT pin can be used to  
trigger multiple groups playback in sequence.  
• VOUT1 and VOUT2 drives buzzer or speaker di-  
rectly  
• Auto-power down  
• 2.4V-6V single power supply operation  
• Low standby current (<5 µA at 3V)  
• Development tools support
