General Description
The HT815D0 is a single chip LOG-PCM voice
synthesizer LSI with 11.2-second voice capacity
at 6kHz sampling rate. The chip when trig-
gered drives a speaker through an external
transistor with a current switch D/A converter
output. Negligible current will be consumed in
the standby state.
TheHT815D0provides12keyinputsand2pro-
grammable 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 sec-
tion 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 HT815D0 is excellent for
versatile voice applications.
Applications
