Part Overview
Description
The DS1678 is a real-time clock (RTC) event recorder that logs the time and date of nonperiodic, asynchronous events. It records the seconds, minutes, hours, date, day of the week, month, year, and century when the first event occurs and starts a 16-bit elapsed time counter (ETC). Subsequent events trigger the recording of the ETC into the event-log memory, allowing for up to 1025 events to be logged.

Features
Real-time clock/calendar in binary-coded decimal (BCD) format
Counts seconds, minutes, hours, date, month, day of the week, and year with leap year compensation and is Year 2000 compliant
Logs up to 1025 consecutive events in read-only battery-backed memory
User-programmable event trigger can be triggered by the falling edge, rising edge, or rising and falling edges of the INT pin
Event counter register provides data on the number of events that have been logged in the current event-logging mission
Programmable RTC alarm
32-byte, battery-backed, general-purpose NVRAM
I²C serial interface
Three resolution options for trade-off accuracy vs. maximum time between events
-40°C to 85°C industrial temperature range
Underwriters Laboratory (UL) recognized

Applications
Event logging
Time stamping
Data acquisition
Security systems
Industrial automation
Medical devices
