DS1339 2 I C Serial Real-Time Clock GENERAL DESCRIPTION BENEFITS AND FEATURES The DS1339 serial real-time clock (RTC) is a low- Completely Manages All Timekeeping power clock/date device with two programmable time- Functions of-day alarms and a programmable square-wave o Real-Time Clock Counts Seconds, output. Address and data are transferred serially 2 Minutes, Hours, Date of the Month, through an I C bus. The clock/date provides seconds, minutes, hours, day, date, month, and year Month, Day of the Week, and Year information. The date at the end of the month is with Leap-Year Compensation Valid automatically adjusted for months with fewer than 31 Up to 2100 days, including corrections for leap year. The clock o Two Time-of-Day Alarms operates in either the 24-hour or 12-hour format with o Programmable Square-Wave Output AM/PM indicator. The DS1339 has a built-in power- sense circuit that detects power failures and o Oscillator Stop Flag automatically switches to the backup supply, Interfaces to Most Microcontrollers maintaining time, date, and alarm operation. 2 o I C Serial Interface APPLICATIONS Low-Power Operation Extends Battery Handhelds (GPS, POS Terminals) Backup Run Time Consumer Electronics (Set-Top Box, Digital o Automatic Power-Fail Detect and Recording, Network Appliance) Switch Circuitry Office Equipment (Fax/Printers, Copier) o Trickle-Charge Capability Medical (Glucometer, Medicine Dispenser) Telecommunications (Routers, Switches, Servers) Underwriters Laboratories (UL) Other (Utility Meter, Vending Machine, Thermostat, Recognized Modem) Surface-Mount Package with an Integrated Crystal (DS1339C Saves Pin Configurations appear at end of data sheet.
