The HT86XXX 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. It has a single built-in high quality, D/A output. There is an external interrupt which can be triggered with fall- ing edge pulse or falling/rising edge pulse. The HT86XXX 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 HT86XXX can be up to 8MHz under 2.4V and include a HALT function to re- duce power consumption. |
