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.
