  • Holtek HT86Bxx語音MCU控制方案
    http://www.ic72.com 发布时间:2009/6/3 16:14:40
    Holtek公司(盛群半导体)的 HT86Bxx是新一代語音MCU系列产品, 包括HT86B05、HT86B10、HT86B20、HT86B30、HT86B40、HT86B50、HT86B60、HT86B70、HT86B80、HT86B90,语音容量范围从36秒到1152秒,语音ROM容量由96KByte到8MByte. HT86Bxx的工作电压从2.2V到5.5V,系统时钟从4MHz到8MHz,提供各种取样频率和节拍,音调大小和节奏,用于语音合成和音调发生器. HT86Bxx还集成了高质量的12位电压型DAC输出.本文介绍了HT86Bxx系列的主要特性,方框图以及多种应用电路.

    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.
