Real-Time Event Recorder

GENERAL DESCRIPTION The DS1678 real-time clock (RTC) event recorder records the time and date of a nonperiodic, asynchronous event each time the INT pin is activated. The device records the seconds, minutes, hours, date, day of the week, month, year, and century when the first event occurs, and s

TRI-STATEé TTL to MOS Multiplexers/Drivers

General Description The DS1648/DS3648 and DS1678/DS3678 are quad 2-input multiplexers with TRI-STATE outputs designed to drive the large capacitive loads (up to 500 pF) associated with MOS memory systems. A PNP input structure is employed to minimize input currents so that driver loading in la

實(shí)時(shí)事件記錄器

DS1678為實(shí)時(shí)時(shí)鐘(RTC)事件記錄儀，用來記錄每次觸發(fā)/INT引腳的非周期、異步事件的時(shí)間和日期。該器件記錄第一次事件發(fā)生時(shí)的秒、分、時(shí)、星期、日期、月、年及世紀(jì)信息，并開啟16位歷時(shí)計(jì)數(shù)器(ETC)。隨后發(fā)生的事件將觸發(fā)ETC記錄，存儲(chǔ)在事件記錄存儲(chǔ)器中。最多可記錄1025個(gè)事件。器件工作在VCC或VBAT供電狀態(tài)時(shí)均可記錄所發(fā)生的事件。 ? BCD格式的實(shí)時(shí)時(shí)鐘/日歷計(jì)算秒、分、時(shí)、日期、月、星期幾以及具有閏年補(bǔ)償、2000年兼容性\n? 在只讀非易失內(nèi)存中，可記錄1025個(gè)連續(xù)事件\n? 事件觸發(fā)由用戶可編程，可以是/INT引腳的下降沿、上升沿或者兩個(gè)邊沿觸發(fā) \n? 事件計(jì)數(shù)寄存器提供已經(jīng)被記錄在當(dāng)前事件記錄任務(wù)中的數(shù)目 \n? 可編程的RTC報(bào)警\n? 用戶可編程的NV RAM (32字節(jié)) \n? I2C串行接口\n? 提供三種分辨率選擇，以折衷考慮精度和最長的事件間隔\n? 工作在-40°C至+85°C工業(yè)級溫度范圍;
