摘要
随着单片机技术的日益发展,以键盘输入和屏幕输出的传统的方式已满足不了人们的需求,新的更友好的人机界面应运而生。本文就是介绍一种基于ISD4002芯片的语音录放电路,该语音芯片采用EEPROM存储方法,将模拟语音数据直接写入半导体存储单元中,不需另加A/D和D/A变换电路,使用方便,且语音音质自然。
With the rapid development of SCM,the traditional method of keybords input/screen output can't satisfy people's requirement.A new and friendly man-nachine interface comes was born.This paper introduces a voice record-replay circuit based on ISD4OO2.This chip use EEPROM and directly write the analog voice data into semiconductor memory unit without A/D and D/A circuits. It is convenient and make the voice natural.
