General Description
TheEasyVoice
TM
isasingle-chipvoicesynthesizerLSI.
The chip when triggered drives a speaker directly or
through an external transistor with a PWM output. Negli-
gible 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 compo-
nents.
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 programma-
ble. With such a flexible structure, the EasyVoice
TM
is
excellent for versatile voice applications.
Applications
