美国ISD公司98年最新推出质优价廉的单片语言电路。特点:该芯片语音录放时间:ISD1506为4.8～9.6秒,ISD1510为8～16秒,ISD1520为16～32秒。时间可调,使用方便。采用CMOS技术,自动进入低功耗状态,静态功耗电流仅0.5μA。芯片采用多电平直接模拟量存储专利技术,每个采样值直接存储在片内单个EEPROM单元中,因此能够非常真实、自然的再现语音、音乐、音调和音效声。具有单段信息处理,无需开发系统。5V单电源工作。
ISD company in the United States in 1998 the latest high-quality low-cost single-chip language circuit. Features: The chip voice recording time: ISD1506 is 4.8 ~ 9.6 seconds, ISD1510 is 8 ~ 16 seconds, ISD1520 is 16 ~ 32 seconds. Adjustable time, easy to use. Using CMOS technology, automatically enter the low-power state, the static power consumption current is only 0.5μA. The chip uses patented multi-level direct analog memory technology, each sample directly stored in a single chip EEPROM unit, it can be very real and natural reproduction of voice, music, tone and sound effects. With a single piece of information processing, no need to develop the system. 5V single power supply.
