General Description

The HT814D0 is a single chip LOG-PCM voice

synthesizer LSI with 8.4-second voice capacity

at a 6kHz sampling rate. The chip when trig-

gered drives a speaker through an external

transistor with a current switch D/A converter

output. Negligible current will be consumed in

the standby state.

The customer¢s voice sources are recorded sec-

tion by section into an internal mask ROM. The

sectional playback arrangement instructions of

each key are stored in the table ROM. The key

features are also programmable. With such a

flexible structure, the HT814D0 is excellent for

versatile voice applications.

The HT814D0 provides 12 key inputs and 2 pro-

grammable FLAG outputs. With a 2.4V~5.0V

power supply, a complete synthesized voice

playback system can be easily built with very

few external components.
