DS1307DTR

The DS1307DTR is a low-power, high-precision real-time clock (RTC) chip with a built-in 56-byte non-volatile RAM (NV SRAM). It is designed for applications that require accurate timekeeping and data retention, such as computers, communication devices, industrial control systems, and embedded systems.

Key Features:

1. Real-Time Clock/Calendar:
   • Provides comprehensive time and date information, including seconds, minutes, hours, day of the week, date, month, and year.
   • Automatically adjusts for months with fewer than 31 days and includes leap-year compensation valid up to the year 2100.
   • Supports both 24-hour and 12-hour time formats with an AM/PM indicator.
2. Low-Power Consumption:
   • Operates within a wide voltage range, typically 4.5V to 5.5V, with low power consumption in both normal and backup modes.
   • Features a power-sense circuit that detects power failures and automatically switches to the backup battery supply to maintain timekeeping and data retention.
3. Serial Communication Interface:
   • Communicates with a microprocessor via an I2C serial interface, allowing for simple and efficient data transfer.
   • Supports read and write operations for both the RTC and NV SRAM.
4. Built-In NV SRAM:
   • Offers 56 bytes of non-volatile RAM for storing time, date, and other configuration information.
   • Retains data even when the power is off, thanks to the backup battery.
5. Flexible Power Options:
   • Supports both primary and backup power supplies to ensure continuous operation during power outages.
   • Internal battery switchover circuitry ensures seamless transition between power sources.
6. Programmable Features:
   • Includes programmable square-wave output for generating periodic signals, such as for driving LCD displays or providing clock signals to other circuits.
   • Supports alarm functions that can generate interrupts when a specific time or date is reached.
7. Package Options:
   • Available in various package configurations, such as SOP-8, to accommodate different PCB layouts and design requirements.

Applications:

• Provides accurate time and date information for computer systems, ensuring the accuracy of system logs and file records.
• Offers time synchronization functionality in communication devices, such as mobile phones, routers, and switches, ensuring reliable and stable network communications.
• Provides timestamp and event recording capabilities in industrial control systems, helping to monitor and track production processes.
• Provides precise time management in embedded systems, such as smart homes, wearable devices, and medical electronics, ensuring devices execute .

In summary, the DS1307DTR is a versatile, low-power RTC chip with built-in NV SRAM, suitable for a wide range of applications requiring accurate timekeeping, data retention, and low power consumption.
