产品概述

The DS1678+ is a real time event recorder in 8 pin DIP package. This real time clock (RTC) event recorder records the time and date of a non-periodic, asynchronous event when each time the active-low INT pin is activated. The device records seconds, minutes, hours, date, day of the week, month, year with leap year compensation, year 2000 compliant, century when first event occurs and starts 16bit elapsed time counter (ETC). Subsequent events trigger recording of 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. User programmable event trigger can be triggered by falling edge, rising edge or rising and falling edges of active-low INT pin. The event counter register provides data on number of events that have been logged in current event logging mission.
  • Power Supply voltage range from 4.5V to 5.5V
  • Operating temperature range from -40°C to 85°C
  • Supports I2C interface
  • Time keeping current of 300nA
  • Active supply current of 1mA
  • Programmable RTC alarm
  • 32byte, battery backed general purpose NV RAM
  • Three resolution options for trade-off, accuracy versus maximum time between events
  • UL recognized
  • SCL clock frequency of 100KHz to 400KHz (fast mode) and 100KHz (standard mode)
