The DS1685SN-3 is an integrated circuit (IC) component designed by Maxim Integrated. It provides real-time clock (RTC) and calendar functionality, making it suitable for a variety of applications that require accurate timekeeping. Here is an overview of its key features:
1. Real-Time Clock: The DS1685SN-3 integrates a high-precision RTC circuitry, enabling it to keep track of the current time and date. It supports both 12-hour and 24-hour time formats and provides automatic leap year compensation.
2. Non-Volatile Memory: This IC utilizes non-volatile memory (NVRAM) to store critical time and date information. The NVRAM allows for data retention even in the absence of power, ensuring that timekeeping data is preserved during power outages or system shutdowns.
3. Trickle Charger: To maintain power for the internal clock and RAM during power loss or system shutdown, the DS1685SN-3 features a built-in trickle charger. It effectively charges the NVRAM using an external backup power supply, such as a super capacitor or battery.
4. Alarm Functionality: The IC offers alarm capabilities to trigger specific events or actions at preset times. It supports multiple programmable alarms, providing flexibility for various application requirements.
5. I2C Interface: The DS1685SN-3 utilizes the widely used I2C (Inter-Integrated Circuit) interface, simplifying its integration into different systems
