DS1307,Real-Time Clock IC with 56 Bytes NV SRAM and I²C Interface,DIP-8

The DS1307 is a versatile real-time clock IC that includes an integrated calendar and 56 bytes of nonvolatile SRAM for user data. Its 2-wire I²C interface simplifies integration with microcontrollers, making it ideal for timekeeping in embedded systems.

The clock operates in both 24-hour and 12-hour formats with AM/PM indication. It features automatic power-fail detection and switching to maintain accurate timekeeping during power outages. Encased in a compact DIP-8 package, the DS1307 is widely used in digital clocks, industrial timers, and data logging systems.

• Real-Time Clock/Calendar: Tracks seconds, minutes, hours, day, date, month, and year with leap year compensation up to 2100.
• Nonvolatile SRAM: 56 bytes of storage for user data retention.
• I²C Serial Interface: Simple 2-wire communication for easy integration with microcontrollers.
• Programmable Square Wave Output: Configurable output frequencies of 1 Hz, 4 kHz, 8 kHz, or 32 kHz.
• Battery Backup Capability: Ensures uninterrupted operation with low power consumption in battery mode (<500 nA).
• Compact DIP-8 Package: Suitable for prototyping and through-hole designs.
