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.
