DATASHEET  
REAL-TIME CLOCK WITH BATTERY BACKED NON-VOLATILE RAM  
IDT1338  
General Description  
Features  
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.  
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  
storage  
Fast mode I2C Serial interface  
Automatic power-fail detect and switch circuitry  
Programmable square-wave output  
Packaged in 8-pin MSOP, 8-pin SOIC, or 16-pin SOIC  
(surface-mount package with an integrated crystal)  
Industrial temperature range (-40°C to +85°C)  
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)
