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 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.
The customer s voice sources are recorded sec-
tion by section into an internal mask ROM. The
instructionsofsectionplaybackarrangementof
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.
Applications
Leisure products
Alarm clocks
Public address system
Alert and warning system
Sound effect generators
