General Description

The HT86R384 series are 8-bit high performance

microcontroller with voice synthesizer and tone genera-

tor. The HT86R384 is designed for applications on mul-

tiple 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 gen-

erator. It has a single built-in high quality, D/A output.

There is an external interrupt which can be triggered

with falling edge pulse or falling/rising edge pulse.

The HT86R384 is excellent for versatile voice and

sound effect product applications. The efficient MCU in-

structions allow users to program the powerful custom

applications. The system frequency of HT86R384 can

be up to 8MHz under 2.4V and include a HALT function

to reduce power consumption.
