GENERAL DESCRIPTION
The DS1307 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 I2 C, 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 backup supply. Timekeeping
operation continues while the part operates from
the backup supply.
FEATURES
♦ Real-Time Clock (RTC) Counts Seconds,
Minutes, Hours, Date of the Month, Month,
Day of the week, and Year with Leap-Year
Compensation Valid Up to 2100
♦ 56-Byte, Battery-Backed, Nonvolatile (NV)
RAM for Data Storage
♦ I2C Serial Interface
♦ Programmable Square-Wave Output Signal
♦ Automatic Power-Fail Detect and Switch Circuitry
♦ Consumes Less than 500nA in Battery-
Backup Mode with Oscillator Running
♦ Optional Industrial Temperature Range:
-40°C to +85°C
♦ Available in 8-Pin Plastic DIP or SO
♦ Underwriters Laboratory (UL) Recognized
