HT81003 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 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 customers 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 HT81003 is excellent for versatile voice applications.
HT81003 Maximum Ratings
Supply Voltage ...........................................-0.3V to 6V
Storage Temperature .......................... -50 to 125
Input Voltage ............................ VSS-0.3V to VDD+0.3V

HT81006 General Description
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 customers 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.
