General Description

The HT81003 is a Mask ROM type. The HT81003 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 provides 2-key inputs and 2 programma-

ble FLAG outputs. With 2.4V~5.0V power supply, a

complete synthesized voice playback system can be

easily built with very few external components.

The customer

¢s voice sources are recorded section 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 programma-

ble. With such a flexible structure, the HT81003 is excel-

lent for versatile voice applications.

Applications

· Leisure products

· Alarm clocks

· Public address system

· Alert and warning system

· Sound effect generators
