DS1307Z SOIC 8 RTC, Date Time Format (Day/Date/Month/Year, HH:MM:SS)

DS1307Z SOIC 8 RTC, Date Time Format (Day/Date/Month/Year, HH:MM:SS)

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.

DNA solutions, Nashik has various types of IC's. Check out our complete collection of IC's.

• Timekeeping:

  • Tracks time in HH:MM:SS format (hours, minutes, seconds).
  • Tracks date in Day/Date/Month/Year format, including leap-year compensation.

• Interface:

  • Operates with an I²C serial interface for communication with microcontrollers.

• Low Power:

  • Powered by an external battery for uninterrupted operation during power failures.
  • Typical battery supply current: <500 nA.

• Oscillator:

  • Uses a 32.768 kHz external crystal oscillator.
  • Internal circuitry compensates for small crystal variations.

• Backup Battery Input:

  • Maintains timekeeping when the primary power source is unavailable.

• Programmable Square-Wave Output:

  • Frequency options: 1Hz, 4kHz, 8kHz, and 32kHz.
