General Description
The HT83XXX is 8-bit high performance microcontroller
with voice synthesizer and tone generator. The
HT83XXX is designed for applications on multiple I/Os
with sound effects, such as voice and melody. It can pro-
vide various sampling rates and beats, tone levels, tem-
pos for speech synthesizer and melody generator.
The HT83XXX is excellent for versatile voice and sound
effect product applications. The efficient MCU instruc-
tions allow users to program the powerful custom appli-
cations. The system frequency of HT83XXX can be up
to 8MHz under 2.4V and include a HALT function to re-
duce power consumption.
