HT86030/HT86070 pdf datasheet

The HT86030/HT86070 series are 8-bit high performance
microcontroller with voice synthesizer and tone
generator. The HT86030/HT86070 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. 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 HT86030/HT86070 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
HT86030/HT86070 can be up to 8MHz under 2.4V and
include a HALT function to reduce power consumption.
