Datasheet Summary

Description

RST CLK DQ GND VCC OSC NC - Reset - Clock - Data Input/Output - Ground - +5V - 1Hz Oscillator Output - No Connect DESCRIPTION The DS1603 is a real-time clock/elapsed time counter designed to count seconds when VCC power is applied and continually count seconds under battery backup power with an a

Features

  • Two 32-bit counters keep track of real-time and elapsed time.
  • Counters keep track of seconds for over 125 years.
  • Battery powered counter counts seconds from the time battery is attached until VBAT is less than 2.5V.
  • VCC powered counter counts seconds while VCC is above VTP and retains the count in the absence of VCC under battery backup power.
  • Clear function resets selected counter to 0.
  • Read/write serial port affords low pin count.
  • Powered internally by a lit.
