本文所要介绍的ISD系列32～120s语音录放电路,具有以下主要特点:(1)为外围元件少、电路简单、操作方便的单片录放系统。(2)直接模拟量存储(DAST)重现优质原声。(3)零功率信息存储,省掉备用电源。(4)信息可保存100年以上,可反复录音达10万次(放音寿命无限)。(5)语音固化无需编程或开发装置。(6)多段信息处理,可分1～320/600段。(7)多片直接级联,延长录放时间。(8)具有自动省电模式,5V单电源工作,维持电
The ISD series 32 ~ 120s voice recording circuit to be introduced in this paper has the following main features: (1) Single-chip recording and reproducing system with few external components, simple circuit and easy operation. (2) Direct Analog Memory (DAST) reproduces high quality soundtrack. (3) zero-power information storage, save backup power. (4) The information can be stored for more than 100 years and can be repeatedly recorded for 100,000 times (unlimited playing life). (5) Voice curing without programming or development device. (6) multi-segment information processing, can be divided into 1 ~ 320/600 segments. (7) Multi-chip direct cascade to extend recording time. (8) with automatic power-saving mode, 5V single power supply to maintain electricity
