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.

longer voice duration. Two devices can be configured in

mixer in which speech can be mixed with background

music each from one of two different chips.

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:

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.
