DATASHEET

REAL-TIME CLOCK WITH SERIAL I

C INTERFACE

General Description

The IDT1339 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 I

C 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 IDT1339 has a built-in power-sense

circuit that detects power failures and automatically

switches to the backup supply, maintaining time, date, and

alarm operation.

IDT1339
