Maxim Integrated DS1302SN+T&R Real-Time Clock

The Maxim Integrated DS1302SN+T&R is a highly compact, serial real-time clock (RTC) with a built-in trickle-charge capability. This versatile timekeeping chip provides a simple and effective solution for adding a timekeeping function to a wide array of electronic applications such as embedded systems, consumer electronics, and industrial control systems.

One of the key features of the DS1302SN+T&R is its trickle-charge timekeeping chip, which contains a real-time clock/calendar and 31 bytes of static RAM. It communicates with a microprocessor via a simple serial interface. The real-time clock/calendar provides seconds, minutes, hours, day, date, month, and year information, and it automatically adjusts for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator.

The DS1302SN+T&R has a low-power consumption design, which makes it an ideal choice for portable battery-operated applications. The device is designed to operate on very low power and retain data and time information on less than 1μW.

Another important feature is the dual power supply pins for the primary and backup supply. The DS1302SN+T&R is fully operational from 2.0 to 5.5 volts and can be powered by a backup battery when the primary power supply is unavailable. This ensures that timekeeping is maintained even when the main system power is turned off.

The device comes in a surface-mount SN package and is available in tape and reel (T&R) form, making it suitable for automated assembly processes. Its compact size and low profile make it an excellent choice for applications where space is at a premium.

For developers and designers, Maxim Integrated provides comprehensive technical support, including detailed datasheets, application notes, and design resources to facilitate integration of the DS1302SN+T&R into various projects.

In summary, the DS1302SN+T&R from Maxim Integrated is a reliable and versatile RTC solution that combines low power consumption with a wide operating voltage range, making it perfect for a multitude of time-sensitive applications where maintaining accurate time is crucial.
