General Description

The HT84XXX family is a series of programma ble speech synthesizers and tone generators de­signed for user-defined voice and melody applications. It provides various sampling rates and beats, tone levels, tempos for the speech synthesizer and melody generator. The HT84XXX series has two built-in high quality, current type D/A outputs with 16 levels of vol­ume control. The user¢s commands enable the user to program the powerful custom function
