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. Preliminary |
