I²C Serial Real-Time Clock

GENERAL DESCRIPTION

FEATURES

The DS1339 serial real-time clock (RTC) is a low-

power clock/date 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 clock/date 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. The DS1339 has a built-in power-

sense circuit that detects power failures and

automatically switches to the backup supply,

maintaining time, date, and alarm operation.

ꢀ

Real-Time Clock (RTC) Counts Seconds, Minutes,

Hours, Day, Date, Month, and Year with Leap-

Year Compensation Valid Up to 2100
