HT83XXX -- Q-VoiceTM
General Description
The HT83XXX series are 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 provide various sampling rates and beats, tone
levels, tempos for speech synthesizer and melody generator.
The HT83XXX is excellent for versatile voice and sound
effect product applications. The efficient MCU instructions
allow users to program the powerful custom applications. The
system frequency of HT83XXX can be up to 8MHz under 2.4V and
include a HALT function to reduce power consumption.
