API8208A - VERSATILE 20 SEC INSTANT VOICE ROM

Datasheet Summary

Description

API8208A is a high quality voice synthesizer capable of varying playback duration.

A proprietary ADPCM algorithm 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.

Features

Minimum 20 second voice length at 6 KHz.
Versatile features for playback.
Combination of voice building blocks extends the duration of playback.
Voice data re-use saves memory space.
Four trigger pins, TG1 to TG4 for eight groups.
SBT for sequential play-all or random play.
Holdable and unholdable, edge and level triggering option.
15 ms debounce time suitable for CDS.
IRP interrupt pin for master reset.
