Overview
The Maxim Integrated DS1307Z is a dedicated Real-Time Clock (RTC) and calendar IC designed for precise timekeeping in embedded systems. Its core functionality lies in maintaining accurate time and date information, even during power loss, via a dedicated battery backup input. A critical design consideration when integrating the DS1307Z is managing the I2C bus contention; while offering a convenient serial interface, careful arbitration is required in multi-master I2C environments to prevent data corruption and ensure reliable communication with the RTC module.
Key Features
- 56 Bytes of NVSRAM for data retention
- I2C (2-Wire Serial) interface
- Operating Voltage: 4.5V to 5.5V
- Battery backup voltage: 2V to 3.5V
- Timekeeping current consumption: 200µA (max @ 5V)
- 8-SOIC (0.154″, 3.90mm Width) surface mount package
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- Logging critical event timestamps in industrial control systems
- Maintaining accurate operational hours for medical devices
- Providing time synchronization for networked IoT nodes
- Date and time stamping for data acquisition modules
