BQ3287AMT INTEGRATED CIRCUIT DIP

The BQ3287AMT is a low-power Real-Time Clock (RTC) integrated circuit (IC) manufactured by Texas Instruments. This RTC is designed to provide accurate timekeeping with minimal power consumption, making it ideal for battery-powered applications and systems requiring long-term time tracking. The BQ3287AMT is housed in a Dual In-line Package (DIP), which facilitates easy integration into breadboards and prototyping boards, as well as legacy systems. This RTC offers a comprehensive set of features, including a calendar, alarm functions, and a programmable square wave output, making it a versatile solution for various time-sensitive applications.

Key features of the BQ3287AMT include a complete RTC function with a calendar extending to the year 2100, automatic leap year compensation, and a programmable alarm function that can trigger an interrupt. It also features a battery backup input, allowing the RTC to continue operating even when the main power supply is removed. The low-power design ensures minimal drain on the battery, extending the system's operational life. The BQ3287AMT communicates with a host microcontroller via a simple parallel interface, simplifying the integration process. The DIP package allows for easy insertion and removal, making it convenient for prototyping and experimentation.

The BQ3287AMT RTC finds applications in a wide range of electronic devices and systems. It is commonly used in data loggers, industrial control systems, point-of-sale (POS) terminals, and embedded systems requiring accurate timekeeping. In data loggers, it provides a timestamp for recorded data, enabling accurate tracking of events over time. In industrial control systems, it can be used to schedule tasks, monitor equipment, and generate alarms. In POS terminals, it provides the current date and time for transaction records. Its low-power consumption and battery backup capability make it suitable for remote monitoring systems and portable devices.

When integrating the BQ3287AMT into a circuit, it is important to consider the power supply requirements and the interface with the host microcontroller. The RTC requires a stable power supply voltage, typically in the range of 2.0V to 5.5V. A 32.768 kHz crystal oscillator is required for accurate timekeeping. The parallel interface allows for easy reading and writing of the RTC registers. The battery backup input should be connected to a suitable battery to maintain timekeeping when the main power is off. Texas Instruments provides comprehensive documentation and application notes to support designers using the BQ3287AMT.

In summary, the BQ3287AMT is a low-power RTC integrated circuit with a complete set of features, including a calendar, alarm functions, and a battery backup input. Its key features include accurate timekeeping, low power consumption, and a simple parallel interface. Its applications include data loggers, industrial control systems, and POS terminals. With its ease of use and reliable performance, the BQ3287AMT is a popular choice for various time-sensitive applications. Ready to add accurate timekeeping to your project?
