DS1339A
Low-Current, I2C, Serial Real-Time Clock
General Description
The DS1339A 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 DS1339A 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)
