HT81XXX -- EasyVoice^TM Speech

The EasyVoiceTM is a single-chip voice synthesizer LSI. The chip when triggered drives a speaker directly or through an external Transistor with a PWM output. Negligible current is consumed in the standby state.
The HT81XXX provides direct key or Matrix key input and 2 programmable 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 programmable. With such a flexible structure, the EasyVoiceTM is excellent for versatile voice applications.
