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
2C 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.
APPLICATIONS
Handhelds (GPS, POS Terminals)
Consumer Electronics (Set-Top Box, Digital
Recording, Network Appliance)
Office Equipment (Fax/Printers, Copier)
Medical (Glucometer, Medicine Dispenser)
Telecommunications (Routers, Switches, Servers)
Other (Utility Meter, Vending Machine, Thermostat,
Modem
)
FEATURES
Real-Time Clock (RTC) Counts Seconds, Minutes,
Hours, Day, Date, Month, and Year with Leap-
Year Compensation Valid Up to 2100
Available in a Surface-Mount Package with an
Integrated Crystal (DS1339C)
