REAL-TIME CLOCK WITH I2C SERIAL INTERFACE DATASHEET IDT1337 The IDT1337 device is a low power serial real-time clock RTC 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 device 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.
