BQ3287EAMT

The BQ3287EAMT is an IC (Integrated Circuit) component developed by Texas Instruments. It is a real-time clock chip that provides clock/calendar, alarm, and programmable square wave functions for various applications. Below is an overview of its key features: 1. Clock and Calendar: The BQ3287EAMT accurately maintains the time and date information, including seconds, minutes, hours, days, months, and years. It supports Leap Year corrections, as well as 24-hour or 12-hour time formats. 2. Non-Volatile RAM (NVRAM): This IC component incorporates 114 bytes of battery-backed non-volatile RAM. This allows important system data, such as configuration settings or user-specific information, to be stored even during power loss or shutdown. 3. Alarm Functions: The BQ3287EAMT offers two independent, programmable alarm outputs with interrupt capabilities. It allows setting daily alarms or specific dates, providing flexibility for different applications. 4. Programmable Square Wave Output: It provides a programmable square wave output signal with a frequency range from 32.768 kHz down to 8 Hz. This feature is useful for generating periodic interrupts or clock signals for other components in the system. 5. Clock Calibration: The IC includes an internal calibration function, allowing users to compensate for crystal frequency variations and temperature changes. This enhances the long-term accuracy of the clock signal
