Overview

The 1337AG device is a low-power serial real-time clock (RTC) device with two programmable time-of-day alarms and a programmable square-wave output. Address and data are transferred serially through an I²C bus. The device provides seconds, minutes, hours, day, date, month, and year information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections for the leap year. The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator.

  • Real-time clock (RTC) counts seconds, minutes, hours, days, dates, months, and year with a leap-year compensation valid up to 2100
  • Packaged in an 8-pin MSOP, 8-pin SOIC, or 16-pin SOIC (surface-mount package with an integrated crystal)
  • I²C serial interface (Normal and Fast modes)
  • Two time-of-day alarms
  • Oscillator Stop Flag
  • Programmable square wave output defaults to 32kHz on power-up
  • Operating voltage of 1.8V to 5.5V
  • Industrial temperature range (-40 °C to +85 °C)

Applications

  • Telecommunication (Routers, Switches, Servers)
  • Handhelds (GPS, POS terminals, MP3 players)
  • Set-Top Box, Digital Recording,
  • Office (Fax/Printers, Copiers)
  • Medical (Glucometer, Medicine Dispensers)
  • Other (Thermostats, Vending Machines, Modems, Utility Meters, Digital Photo Frame devices)
