REAL-TIME CLOCK WITH I²C SERIAL INTERFACE

IDT1337AG

General Description

Features

The IDT1337AG 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

• Real-Time Clock (RTC) counts seconds, minutes, hours,

day, date, month, and year with leap-year compensation

valid up to 2100

data are transferred serially through an I C bus. The device

• Packaged in 8-pin MSOP, 8-pin SOIC, or 16-pin SOIC

(surface-mount package with an integrated crystal)

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 leap year. The clock operates in

either the 24-hour or 12-hour format with AM/PM indicator.

• I C serial interface (Normal and Fast modes)

• Two time-of-day alarms

• Oscillator stop flag

Applications

• Programmable square-wave output defaults to 32kHz on

power-up

• Telecommunication (Routers, Switches, Servers)

• Handhelds (GPS, POS terminals, MP3 players)

• Set-Top Box, Digital Recording,

• Operating voltage of 1.8 to 5.5V

• Industrial temperature range (-40 to +85°C)

• Office (Fax/Printers, Copiers)

• Medical (Glucometer, Medicine Dispensers)

• Other (Thermostats, Vending Machines, Modems, Utility

Meters, Digital Photo Frame devices)
