The DS1306EN from Maxim Integrated is a serial alarm real-time clock (RTC) that provides a comprehensive solution for timekeeping in a wide range of applications. This advanced RTC integrates a programmable time-of-day alarm, a programmable square-wave output, and 96 bytes of nonvolatile RAM. Its dual-alarm functionality allows users to set two distinct alarms, making it an ideal component for devices requiring complex time management features.

Key Features

• Real-Time Clock/Calendar: Tracks time with precision in hours, minutes, and seconds, and maintains a full calendar, including day, date, month, and year information.
• Dual Programmable Alarms: Offers the ability to set two separate alarms, each with the capability to trigger an interrupt or a square-wave output.
• Serial Interface: Equipped with a simple serial interface that supports SPI or 3-wire modes for easy integration with a wide range of microcontrollers and systems.
• Nonvolatile RAM: Features 96 bytes of NV RAM, providing battery-backed storage for critical data that must be preserved during power loss.
• Low Power Consumption: Designed for efficient operation, it consumes minimal power, which is critical for battery-powered devices.
• Trickle-Charge Capability: Includes a trickle-charge input that allows for a rechargeable energy source to maintain the clock and RAM data in the absence of primary power.

Applications

The DS1306EN is suitable for a diverse range of applications that require accurate timekeeping and data retention, including:

• Embedded systems
• Utility meters
• Security systems
• Data loggers
• Consumer electronics
