General Description

The HT81003 is a Mask ROM type and

HT81R03 is an OTP type. The HT81003/

HT81R03 is a single-chip voice synthesizer LSI

with 3-second voice capacity at 5kHz sampling

rate. The chip when triggered drives a speaker

through an external transistor with a PWM

output. Negligible current is consumed in the

standby state.

The customer¢s voice sources are recorded sec-

tion by section into an internal mask ROM. The

instructions of section playback arrangement of

each key are stored in the table ROM. The key

features are also programmable. With such a

flexible structure, the HT81003/HT81R03 is ex-

cellent for versatile voice applications.

The HT81003/HT81R03 provides 2-key inputs

and 2 programmable FLAG outputs. With

2.4V~5.0V power supply, a complete synthe-

sized voice playback system can be easily built

with very few external components.
