GENERAL DESCRIPTION
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 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 DS1339 has a built-in power-
sense circuit that detects power failures and
automatically
switches
to
maintaining time and date operation.
