Description

The HT814D0 is a single chip LOG-PCM voice synthesizer LSI with 8.4-second voice capacity at a 6kHz sampling rate. The chip when triggered drives a speaker through an external transistor with a current switch D/A converter output. Negligible current will be consumed in the standby state.

The HT814D0 provides 12 key inputs and 2 programmable FLAG outputs. With a 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 sectional playback arrangement instructions of each key are stored in the table ROM. The key features are also programmable. With such a flexible structure, the HT814D0 is excellent for versatile voice applications.
