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 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 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.
Applications
Handhelds (GPS, POS terminals)
Consumer Electronics (Set-Top Box, Digital Recording,
Network Applications)
Office (Fax/Printers, Copiers)
Medical (Glucometer, Medicine Dispensers)
Telecomm (Routers, Switches, Servers)
Other (Thermostats, Vending Machines, Modems, Utility
Meters)
