DS1338U-3+ Real-Time Clock from Maxim Integrated

The DS1338U-3+ is a highly integrated real-time clock (RTC) from Maxim Integrated that offers a comprehensive timekeeping solution for a wide range of applications. This device is designed to maintain accurate time and date information, from seconds to years, and it is particularly suitable for systems that require reliable timekeeping functionality with minimal power consumption.

This RTC is equipped with a built-in power-sense circuit that detects power failures and automatically switches to the backup supply, ensuring that timekeeping continues uninterrupted. The DS1338U-3+ operates over a wide voltage range and features a serial interface that is fully I²C-compatible, making it easy to integrate into existing designs.

Key features of the DS1338U-3+ include:

• 56-Byte, Battery-Backed, General-Purpose RAM
• Low Power Consumption
• Completely Manages All Timekeeping Functions
• Real-Time Clock Counts Seconds, Minutes, Hours, Date, Month, Day, Year, and Leap-Year up to the year 2100
• I²C Serial Interface
• Automatic Power-Fail Detect and Switch Circuitry
• Trickle-Charge Capability
• -40°C to +85°C Operating Temperature Range
• 8-Pin µSOP and SO Packages

The device's trickle-charge feature allows for the addition of an external capacitor or rechargeable battery, which can be used to maintain the time and date in the event of a primary power failure. The DS1338U-3+ is also notable for its compact 8-pin µSOP and SO packaging options, which make it an ideal choice for space-constrained applications.

Whether you are designing consumer electronics, embedded systems, or industrial control panels, the DS1338U-3+ offers a reliable and easy-to-use timekeeping solution that can significantly reduce the complexity and cost of your designs.
