产品概述

The DS1371U+ is an I2C, 32bit binary counter watchdog clock in 8 pin µSOP package. This device is an industry's lowest cost single supply binary timekeeper for ultra low power applications. It is designed to continuously count time in seconds. An additional counter that can generate periodic alarm or serve as a watchdog timer is also provided. If enabled as a watchdog timer, the watchdog strobe input pin provides hardware reset of counter. If disabled, this counter can be used as 3bytes of general purpose RAM. A configurable output can be used as an interrupt or provide a square wave at one of four selectable frequencies. The device is programmed serially through I2C bidirectional bus. It is used in servers and elapsed time measurements.
  • Supply voltage range from 1.7V to 5.5V
  • Operating temperature range from -40°C to 85°C
  • SCL clock frequency from to 100KHz to 400KHz (fast mode) and 100KHz (standard mode)
  • Timekeeping current of 800nA (osc enabled, INTCN = 1) and 1300nA (osc enabled, INTCN = 0)
  • 24bit binary counter provides periodic alarm, watchdog timer or RAM
  • Strobe input to reset watchdog timer and watchdog strobe (WDS) pulse width of 100ns
  • Single output configurable as interrupt or square wave
  • Low voltage operation
  • Oscillator operating voltage range from 1.3V to 5.5V
  • Active supply current of 100µA and data retention current of 100nA
