API840 - 32 to 40 SEC INSTANT VOICE ROM

Datasheet Summary

Description

API840N is a high-quality voice synthesizer with a capacity of 32 to 40 seconds.

A proprietary ADPCM algorithm is used.

The audio message is stored in a 1024-Kbit on-chip EPROM.

Features

Voice length at - 8 KHz sampling is 32 seconds - 6 KHz sampling is 40 seconds.
Silence compression to save memory.
Eight trigger pins,TG1 to TG8 for 32 sections.
SBT pin play-all or sequential play-all.
15 ms debounce time suitable for CDS.
IRP interrupt pin stops playback at once.
STP stop pulse generated at end of playback.
BUSY signal for CPU control.
Two LEDs flash at 3 Hz internal.
3.0V to 6V single power supply operation.
Low standby.
