DS1307ZN Description

Short technical summary and product information.

The DS1307ZN is a serial real-time clock (RTC) and calendar from Dallas Semiconductor, offering comprehensive timekeeping functions. It counts seconds, minutes, hours, day, date, month, and year, with leap-year compensation valid up to 2100. The device includes 56 bytes of battery-backed, general-purpose NV SRAM with unlimited write capability.

Designed for low power consumption, the DS1307ZN consumes less than 500nA in battery-backup mode with the oscillator running. It features an I2C serial interface for easy integration with most microcontrollers. A built-in power-sense circuit detects power failures and automatically switches to a backup supply, ensuring continuous timekeeping operation. The clock operates in either 24-hour or 12-hour format with an AM/PM indicator.

Available in both 8-pin PDIP and 8-pin SO packages, the DS1307ZN minimizes required space. It supports an optional industrial temperature range of -40°C to +85°C, making it suitable for a wide range of applications. The device also provides a programmable square-wave output signal.
