HT86A72数据手册Holtek中文资料规格书

描述 Description

The devices are Voice type series 8-bit high performance 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 external 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 development cycles.
