The DS1689SN+T&R is an Integrated Circuit (IC) component manufactured by Maxim Integrated.
This IC is a real-time clock (RTC) module with nonvolatile memory and a digital thermometer. It is designed for applications requiring precision timing, temperature monitoring, and data logging.
Key Features:
1. Real-Time Clock Functionality: The DS1689SN+T&R provides highly accurate time and date information. It supports leap years and has the capability to switch automatically between standard and daylight saving time.
2. Nonvolatile Memory: The IC includes 4096 bytes of nonvolatile static random-access memory (NVSRAM). This memory can be used to store critical data even when power is lost or turned off. It ensures data integrity and security.
3. Digital Thermometer: The DS1689SN+T&R incorporates a built-in digital thermometer. It provides accurate temperature measurements with a resolution of 0.5 degrees Celsius. The thermometer data can be accessed and utilized by the user for temperature monitoring applications.
4. I2C Interface: The IC communicates with other devices using the I2C serial interface protocol. This allows for easy integration into a wide range of systems, including microcontrollers and embedded systems.
5. Battery Backup: The DS1689SN+T&R includes a power-fail input pin, which allows integrating an external battery backup for maintaining timekeeping and memory functions during a power loss
