General Description

The devices are Voice type series 8-bit high perfor-

mance microcontrollers which include a voice

synthesiser and tone generator. They are specifically

designed for applications which require multiple I/Os

and sound effects, such as voice and melodies. They

can provide various sampling rates and beats, tone

levels, tempos for speech synthesisers and melody

generators. They also include an integrated high

quality, voltage type DAC output, an integrated series

protocol interface, multi-channel A/D Converter and

integrated power amplifier for speaker driving. The ex-

ternal interrupt can be triggered with falling edges or

both falling and rising edges.

The devices are fully supported by the Holtek range of

fully functional development and programming tools,

providing a means for fast and efficient product devel-

opment cycles.
