1 / 25 page  DS1678 Real-Time Event Recorder www.maxim-ic.com 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 starts the 16- bit elapsed time counter (ETC). Subsequent events trigger the recording of the ETC into the event-log memory. This allows for up to 1025 events to be logged. Events can be logged while the device is operating from either VCC or VBAT. PIN CONFIGURATION 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 TYPICAL OPERATING CIRCUIT Programmable RTC Alarm 32-Byte, Battery-Backed, General-Purpose NV RAM 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 ORDERING INFORMATION PART† PIN-PACKAGE TOP MARK†† DS1678 8 Plastic DIP DS1678 DS1678+ 8 Plastic DIP DS1678 DS1678S 8 SO DS1678S DS1678S+ 8 SO DS1678S DS1678S/T&R 8 SO (Tape and Reel) DS1678S DS1678S+T&R 8 SO (Tape and Reel) DS1678S TOP VIEW † All devices are specified over the -40°C to +85°C operating range. †† A “‘+” anywhere on the top mark denotes a lead-free device. + Denotes a lead-free/RoHS-compliant device. * I2C is a trademark of Philips Corp.
