DS3231SN#T&R

The DS3231SN#T&R is a real-time clock (RTC) IC manufactured by Maxim Integrated. It is part of the DS3231 series, known for its high accuracy, low power consumption, and advanced features suitable for a wide range of applications requiring precise timekeeping functionality.

Key Features:

• High Accuracy: The DS3231SN#T&R offers exceptional timekeeping accuracy, with typical deviation of only a few seconds per month, ensuring reliable and precise timekeeping in various applications.
• Integrated Crystal Oscillator: The RTC IC incorporates a highly accurate temperature-compensated crystal oscillator (TCXO), which eliminates the need for an external crystal, simplifying system design and reducing component count.
• Battery Backup: It features a built-in power-fail detection circuit and supports battery backup, allowing the RTC to maintain accurate timekeeping even during power interruptions or when the main power source is unavailable.
• I2C Interface: The DS3231SN#T&R communicates with the host microcontroller or system via the I2C (Inter-Integrated Circuit) serial interface, providing easy integration and control.
• Alarm Functionality: It supports programmable alarms with multiple alarm configurations, enabling the RTC to trigger interrupts or wake-up signals at specified times or dates.
• Temperature Sensor: The RTC IC includes an integrated temperature sensor with ±3°C accuracy, allowing temperature-compensated timekeeping and temperature monitoring applications.
• Digital Trim: It features digital trimming capabilities for fine-tuning the oscillator frequency, enabling calibration and adjustment to compensate for frequency drift over time or temperature variations.
• Low Power Consumption: With ultra-low power consumption characteristics, the DS3231SN#T&R is suitable for battery-powered and energy-efficient devices, prolonging battery life and minimizing power consumption.
• Small Footprint: Housed in a compact TDFN (Thin Dual Flat No-Lead) package, the RTC IC offers a small footprint, making it ideal for space-constrained applications and compact electronic devices.
