REAL-TIME CLOCK WITH BATTERY BACKED NON-VOLATILE RAM
IDT1338
IDT REAL-TIME CLOCK WITH BATTERY BACKED NON-VOLATILE RAM 1
IDT1338
REV M 092211
General Description
The IDT1338 is a serial real-time clock (RTC) device that
consumes ultra-low power and provides a full binary-coded
decimal (BCD) clock/calendar with 56 bytes of battery
backed Non-Volatile Static RAM. The clock/calendar
provides seconds, minutes, hours, day, date, month, and
year information. The clock operates in either the 24-hour
or 12-hour format with AM/PM indicator. The end of the
month date is automatically adjusted for months with fewer
than 31 days, including corrections for leap year. Access to
the clock/calendar registers is provided by an I2C interface
capable of operating in fast I2C mode. Built-in Power-sense
circuitry detects power failures and automatically switches
to the backup supply, maintaining time and date operation.
Applications
Telecom (Routers, Switches, Servers)
Handheld (GPS, Point of Sale POS terminals)
Consumer Electronics (Set-Top Box, Digital Recording,
Network Applications, Digital photo frames)
Office (Fax/Printers, Copiers)
Medical (Glucometer, Medicine Dispensers)
Others (Thermostats, Vending Machines, Modems, Utility
Meters)
Features
Real-Time Clock (RTC) counts seconds, minutes, hours,
day, date, month, and year with leap-year compensation
valid up to 2100
56-Byte battery-backed Non Volatile RAM for data
