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

实时事件记录器

DS1678为实时时钟(RTC)事件记录仪，用来记录每次触发/INT引脚的非周期、异步事件的时间和日期。该器件记录第一次事件发生时的秒、分、时、星期、日期、月、年及世纪信息，并开启16位历时计数器(ETC)。随后发生的事件将触发ETC记录，存储在事件记录存储器中。最多可记录1025个事件。器件工作在VCC或VBAT供电状态时均可记录所发生的事件。 • BCD格式的实时时钟/日历计算秒、分、时、日期、月、星期几以及具有闰年补偿、2000年兼容性\n• 在只读非易失内存中，可记录1025个连续事件\n• 事件触发由用户可编程，可以是/INT引脚的下降沿、上升沿或者两个边沿触发 \n• 事件计数寄存器提供已经被记录在当前事件记录任务中的数目 \n• 可编程的RTC报警\n• 用户可编程的NV RAM (32字节) \n• I²C串行接口\n• 提供三种分辨率选择，以折衷考虑精度和最长的事件间隔\n• 工作在-40°C至+85°C工业级温度范围;
