The Maxim Integrated DS1307Z is a highly versatile and widely used Real-Time Clock (RTC) integrated circuit, designed to provide precise time and date information for a broad range of applications. This 8-pin SOIC (Small Outline Integrated Circuit) device uses an I2C interface for communication, making it easy to integrate into various microcontroller-based systems.

Key Features

• 56-Byte, Battery-Backed, Nonvolatile (NV) RAM: Allows for storage of critical data that must be preserved across power cycles.
• Low Power Consumption: Designed for power-sensitive applications, the DS1307Z operates on a very low current, helping to extend battery life in portable devices.
• Fully Addressable Calendar: 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.
• I2C Serial Interface: Offers a simple, bidirectional two-wire bus for easy communication with other microcontrollers and devices.
• Programmable Square-Wave Output Signal: This feature allows the DS1307Z to be used for various applications that require a periodic interrupt or a clock-driven event.
