DS1307Z+ – DALLAS

Overview

The Analog Devices Inc./Maxim Integrated DS1307Z+ is a highly integrated Real-Time Clock (RTC) IC designed for precise timekeeping and calendar functions. Its core strength lies in its robust I2C serial interface and low power consumption, making it ideal for battery-backed applications. A critical design consideration when implementing the DS1307Z+ is managing the trade-off between its 200µA typical timekeeping current and the battery backup voltage range (2V to 3.5V); exceeding the maximum battery voltage can potentially damage the device or reduce its operational lifespan, necessitating careful power supply design.
