1 / 24 page  DATASHEET REAL-TIME CLOCK WITH I2C SERIAL INTERFACE IDT1337 IDT™ REAL-TIME CLOCK WITH I2C SERIAL INTERFACE 1 IDT1337 REV J 111009 General Description The IDT1337 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 leap year. The clock operates in either the 24-hour or 12-hour format with AM/PM indicator. 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) Features • Real-Time Clock (RTC) counts seconds, minutes, hours, day, date, month, and year with leap-year compensation valid up to 2100 • Packaged in 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 32 kHz on power-up • Operating voltage of 1.8 to 5.5 V • Industrial temperature range (-40 to +85°C) Block Diagram SCL SDA Crystal inside package for 16-pin SOIC ONLY X1 X2 1 Hz/4.096 kHz/ 8.192 kHz/32.768 kHz SQW/INTB I 2C Interface 32.768 kHz Oscillator and Divider Control Logic MUX/ Buffer Clock, Calendar Counter 1 Byte Control 7 Bytes Buffer Alarm Registers INTA VCC GND |
