General Description

The HT83R074 is 8-bit high performance microcontroller

with voice synthesizer and tone generator. The

HT83R074 is designed for applications on multiple I/Os

with sound effects, such as voice and melody. It can pro-

vide various sampling rates and beats, tone levels, tem-

pos for speech synthesizer and melody generator.

The HT83R074 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 HT83R074 can

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

to reduce power consumption.
