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.
