IDT1337G - REAL-TIME CLOCK

General Description

The IDT1337G 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.

Key Features

  • Real-Time Clock (RTC) counts seconds, minutes, hours, day, date, month, and year with leap-year compensation valid up to 2100.
  • Packaged in 8-pin MSOP, 8-pin SOIC, 16-pin VFQFPN (without integrated crystal), or 16-pin SOIC (surface-mount package with an integrated crystal).
  • I2C Serial interface (Normal and Fast modes).
  • Two time-of-day alarms.
  • Oscillator Stop Flag.
  • Programmable square-wave output defaults to 32 kHz on power-up.
  • Operat.

REAL-TIME CLOCK WITH I2C SERIAL INTERFACE DATASHEET IDT1337G General Description The IDT1337G 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. The clock operates in either the 24-hour or 12-hour format with AM/PM indicator.
