HT86B50中文资料Enhanced Voice 8-Bit MCU数据手册Holtek规格书

描述 Description

The Voice type series of MCUs are 8-bit high performance microcontrollers which include a voice synthesizer and tone generator. They are designed for applications which require multiple I/Os and sound effects, such as voice and melody. The devices can provide 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 triggered 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
