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.
Features
• Operating voltage: 2.4V~5V
• Directly drives an external transistor
