XBLW DS1307DTR 64X8 Serial Real Time Clock SMD IC SOP-8
The XBLW DS1307DTR is a low-power real-time clock (RTC) integrated circuit designed to maintain time and calendar information in electronic systems. It tracks seconds, minutes, hours, day of the week, date, month, and year, with automatic calendar adjustment for months of different lengths and leap-year compensation through 2100. The clock supports both 12-hour and 24-hour formats.
Features:
- Full binary-coded decimal (BCD) clock/calendar with leap-year compensation valid up to 2100.
- 56 bytes of nonvolatile SRAM for reliable data storage during power interruptions.
- Standard 2-wire serial I2C interface for simplified microcontroller communication.
- Programmable square-wave output signal for system timing and synchronization.
- Automatic power-fail detection and seamless switch circuitry to backup battery.
