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

歷時記錄器，帶有鬧鐘功能

DS1682為集成的歷時記錄器，包含一個工廠校準(zhǔn)、溫度補(bǔ)償?shù)腞C時間基準(zhǔn)，無需外部晶振。在沒有電源的情況下，DS1682使用EEPROM技術(shù)來保存數(shù)據(jù)，所以無需備份電源。從上次復(fù)位為零開始，DS1682將檢測并記錄在EVENT引腳上的事件數(shù)以及總的事件累積時間。DS1682檢測并記錄在EVENT引腳出現(xiàn)的事件數(shù)以及DS1682最后一次復(fù)位至0后總的事件累計(jì)時間。一旦總累積時間等于用戶設(shè)置的報(bào)警值時，/ALARM引腳將告知用戶。漏極開路/ALARM引腳的輸出極性可以設(shè)置為低有效或高阻態(tài)有效。DS1682尤其適合于那些監(jiān)測累計(jì)時間的應(yīng)用，如自從開始服務(wù)、修理或上次校準(zhǔn)后，設(shè)備投入運(yùn)行的總時間，或所 ? 記錄事件輸入被激活的總時間以及事件發(fā)生的次數(shù)\n? 32位、非易失性、歷時計(jì)數(shù)器(ETC)監(jiān)控事件過程，具有四分之一秒的分辨率和34年的總累積時間\n? 可編程的歷時/ALARM輸出\n? 非易失17位事件計(jì)數(shù)器記錄事件發(fā)生的總次數(shù) \n? 校準(zhǔn)、溫度補(bǔ)償RC時間基準(zhǔn)典型精度達(dá)到2%\n? 10字節(jié)EEPROM用戶存儲器\n? 寫禁止功能避免存儲器改寫或刪除 \n? 2線串行通訊\n? 2.5V至5.5V的寬電源范圍 \n? 適合于保質(zhì)期、校準(zhǔn)、維修以及維護(hù)等時間應(yīng)用;
