DS1307 TIMERCLOCK IC

The DS1307 Serial Real-Time Clock is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially via a 2-wire, bidirectional bus. 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 DS1307 has a built-in power sense circuit that detects power failures and automatically switches to the battery supply.

• • It’s a full binary coded decimal clock.
  • Address and data are transferable via microcontroller unit.
  • Operating temperature ranges from -40°C to 85°C
  • Automatic power fails to detect and switch circuitry making time keeping continuous
  • Timekeeping current as low as 300nA
  • Completely manages all time keeping functions without mcu intervention.
  • 56byte, battery backed, general purpose RAM with unlimited writes.
  • A programmable square wave output signal for clock sequence.
  • Simple serial port interfaces to most microcontrollers, I2C specified.
  • Low power operation extends battery backup runtime.
  • Consumes less than 500nA in battery backup mode with oscillator running.

Applications:

• • Real time clock
  • Time keeping
  • Digital calendar
  • Storage for time and Date
  • Clocks without GPS

Package Includes:

• • 1 x DS1307 IC – Real Time Clock (RTC) IC
