General Description
The HT83XXX series are 8-bit high performance
microcontroller with voice synthesizer and tone genera-
tor. The HT83XXX is designed for applications on multi-
ple I/Os with sound effects, such as voice and melody. It
can provide various sampling rates and beats, tone lev-
els, tempos for speech synthesizer and melody genera-
tor.
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.
