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.
