GENERAL DESCRIPTION  
IS22C012 is a high quality voice synthesizer capable of  
varyingplaybackduration. AproprietaryADPCMalgorithm  
is used. The audio message is stored in a 256K bits on-  
chip EPROM which can store up to ten seconds of voice  
data at 6 KHz sample rate.  
Group of sections  
The voice data memory area of the IS22C012 can be  
subdivided into 124 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.  
TheIS22C012eliminatestheneedofcomplicatedcircuitry  
in voice playback but still achieves high voice quality.

Versatilecombinationsinsectionsachievelongerplayback  
duration. In addition, devices can be cascaded to achieve  
longer voice duration. Two devices can be configured in  
parallelinordertoachievesignalmixingwithoutanexternal  
mixer in which speech can be mixed with background  
music each from one of two different chips.  
Group Configuration

the fundamental voice building blocks for arranging  
playback without limiting sequencing. This provides  
flexibility and allows data to be re-used, beneficial for  
applications with many repeated sounds or words.  
An example of group configuration is illustrated below:

Sec 3 + Sec 2  
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.
