Maxim Integrated DS1302SN+T Real-Time Clock

The Maxim Integrated DS1302SN+T is a highly versatile real-time clock (RTC) module that provides a simple and effective solution for timekeeping in a wide range of electronic applications. This compact, serial interface RTC is designed for microcontrollers with limited input/output (I/O) resources and offers low-power consumption, making it ideal for battery-powered devices.

Key Features:

• Trickle-Charge Timekeeping Chip: The DS1302SN+T includes a trickle-charge capability that allows an external capacitor or a rechargeable battery to be connected directly to the device. This ensures that timekeeping is maintained even when the main power supply is turned off.
• Serial Interface: The device communicates with microcontrollers via a simple, three-wire interface, which minimizes pin usage and simplifies integration into design projects.
• Low Power Consumption: Designed for energy efficiency, the DS1302SN+T draws less than 300nA of current when operating in battery-backup mode with VCC1 grounded, extending the life of your backup energy source.
• Wide Operating Voltage: It operates over a wide voltage range of 2.0V to 5.5V, compatible with most microcontrollers and allowing for flexible design options.
• 56-Byte, Battery-Backed, General-Purpose RAM: The integrated RAM provides additional storage for data that needs to be preserved during power loss, further enhancing the chip's utility.
• Compact Surface-Mount Package: The DS1302SN+T is available in an 8-pin SO (150 mil) surface-mount package, making it suitable for space-constrained applications.

Applications:

The DS1302SN+T is a perfect fit for applications that require accurate timekeeping, data logging, or scheduled operations, including:

• Handheld devices
• Consumer electronics
• Industrial systems
• Healthcare devices
• Embedded systems

With its combination of features, the Maxim Integrated DS1302SN+T provides a reliable and cost-effective solution for adding real-time clock functionality to your electronic projects. Its ease of integration, coupled with Maxim Integrated's reputation for quality, makes the DS1302SN+T a smart choice for designers and engineers looking to enhance their systems with timekeeping capabilities.
