GENERAL DESCRIPTION

The DS1338 serial real-time clock (RTC) is a low power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I2C interface. The clock/calendar provides seconds, minutes, hours, day, date, month, and year

information. The end of the month date 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 DS1338 has a built-in power sense circuit that detects power failures and automatically switches to the backup supply, maintaining time and date operation

FEATURES

● RTC Counts Seconds, Minutes, Hours, Date of the Month, Month, Day of the Week, and Year with Leap-Year Compensation Valid Up to 2100

● Available in a Surface-Mount Package with an Integrated Crystal (DS1338C)

● 56-Byte Battery-Backed General-Purpose RAM with Unlimited Writes

● I2C Serial Interface

● Programmable Square-Wave Output Signal

● Automatic Power-Fail Detect and Switch Circuitry

● -40C to +85C Operating Temperature Range

● Underwriters Laboratory (UL) Recognized

APPLICATIONS

Handhelds (GPS, POS Terminal)

Consumer Electronics (Set-Top Box, Digital Recording, Network Appliance)

Office Equipment (Fax/Printer, Copier)

Medical (Glucometer, Medicine Dispenser)

Telecommunications (Router, Switcher, Server)

Other (Utility Meter, Vending Machine, Thermostat,Modem)
