General Description

The Voice type series of MCUs are 8-bit high perfor-

mance microcontrollers which include a voice synthe-

sizer and tone generator. They are designed for

applications which require multiple I/Os and sound ef-

fects, such as voice and melody. The devices can pro-

vide various sampling rates and beats, tone levels,

tempos for speech synthesizer and melody generator.

They also include an integrated high quality, voltage

type DAC output. The external interrupt can be trig-

gered with falling edges or both falling and rising edges.

The devices are excellent solutions for versatile voice

and sound effect product applications with their efficient

MCU instructions providing the user with programming

capability for powerful custom applications. The system

frequency can be up to 8MHz at an operating voltage of

2.2V and include a power-down function to reduce

power consumption.
