APT380

    APT380是一款80秒易用语音集成电路,支持PWM或DAC语音输出,语音质量高,在6kHz采样和4位硬件压缩下有80秒的语音长度。

    其内部内置一个振荡器,用于系统时钟,无需外部电阻器。最多63个语音组。一组包含几个步骤(语音部分);所有组最多700步。每个步骤可定义触发模式、输出状态、语音部分、静音长度、I/O类型和简单编程功能。

    用户可以选择8位/5位/4位数据压缩。支持三模式触发IC(独立、串行触发模式、CPU命令模式)。易于使用的开发系统用于功能选择和语音组合。PC通过USB端口下载ROM代码。
    APT380 Description:
        APT380 is a 80 Sec Easy Use Speech IC .It Support PWM or DAC voice output with high quality speech , There are 80 second Voice Length under 6 KHz sampling and 4 bit hardware compression. Its internal built-in a oscillator for system clock without an external resistor. Maximum 63 voice groups. One Group contain several steps(voice section ); Maximum 700 steps for all the Groups. Each Step can be define Trigger Mode, Output Status, Voice Section, Mute length, I/O Type & Simple Programming Function. User can select 8bit / 5bit / 4bit data compression. Support three mode trigger IC (Stand Alone, Serial Trigger Mode, CPU Command Mode ). Easy use development system is for function selection and voice combination . PC download the ROM code by the USB Port .
