The DS1307Z is a widely used IC component developed by Maxim Integrated. It is a Real-Time Clock (RTC) chip that serves as an accurate timekeeping solution for various electronic devices. This IC is commonly used in applications such as digital clocks, data loggers, and time-stamping devices.
Key features of the DS1307Z include:
1. Real-Time Clock: The DS1307Z provides precise time measurement in hours, minutes, seconds, and fractional seconds. It also incorporates a calendar with day, date, month, and year tracking.
2. Battery Backup: The IC has built-in battery backup support, allowing it to continue timekeeping functions even when the main power supply is disconnected. This ensures that the clock remains accurate, preventing time loss.
3. I2C Interface: The DS1307Z utilizes the I2C (Inter-Integrated Circuit) communication protocol, enabling easy integration with microcontrollers and other digital systems. This two-wire serial interface simplifies communication and allows for multiple devices to be connected on the same bus.
4. 56-Byte Nonvolatile RAM: In addition to timekeeping capabilities, the DS1307Z features 56 bytes of nonvolatile RAM for general-purpose data storage. This RAM can be used to store settings, user preferences, or data log entries.
5. Programmable Square Wave Output: The IC generates a programmable square wave output with frequencies ranging from 1Hz to 32.768kHz
