10 Bytes of EEPROM User Memory

General Description The DS1682 is an integrated elapsed-time recorder containing a factory-calibrated, temperature-compensated RC time base that eliminates the need for an external crystal. Using EEPROM technology to maintain data in the absence of power, the DS1682 requires no backup power sourc

Total Elapsed Time Recorder with Alarm

DESCRIPTION The DS1682 is an integrated elapsed time recorder that will provide the total amount of time that an event is/has been active since the DS1682 was last reset to zero via the 2-wire bus. When the total time accumulated is equal to the preset alarm trip point and the polarity bit is set

历时记录器，带有闹钟功能

DS1682为集成的历时记录器，包含一个工厂校准、温度补偿的RC时间基准，无需外部晶振。在没有电源的情况下，DS1682使用EEPROM技术来保存数据，所以无需备份电源。从上次复位为零开始，DS1682将检测并记录在EVENT引脚上的事件数以及总的事件累积时间。DS1682检测并记录在EVENT引脚出现的事件数以及DS1682最后一次复位至0后总的事件累计时间。一旦总累积时间等于用户设置的报警值时，/ALARM引脚将告知用户。漏极开路/ALARM引脚的输出极性可以设置为低有效或高阻态有效。DS1682尤其适合于那些监测累计时间的应用，如自从开始服务、修理或上次校准后，设备投入运行的总时间，或所 • 记录事件输入被激活的总时间以及事件发生的次数\n• 32位、非易失性、历时计数器(ETC)监控事件过程，具有四分之一秒的分辨率和34年的总累积时间\n• 可编程的历时/ALARM输出\n• 非易失17位事件计数器记录事件发生的总次数 \n• 校准、温度补偿RC时间基准典型精度达到2%\n• 10字节EEPROM用户存储器\n• 写禁止功能避免存储器改写或删除 \n• 2线串行通讯\n• 2.5V至5.5V的宽电源范围 \n• 适合于保质期、校准、维修以及维护等时间应用;
