DS1302ZN+T&R

The DS1302ZN+T&R is a real-time clock (RTC) integrated circuit (IC) designed by Maxim Integrated (now part of Analog Devices). It provides timekeeping functions, including seconds, minutes, hours, day, date, month, and year information. It can automatically adjust for months with fewer than 31 days and leap years until the year 2100.
The DS1302 features a trickle-charge capability to maintain timekeeping even when the main power supply is interrupted, using an auxiliary battery or supercapacitor. It communicates with a microcontroller using a simple serial interface that can be easily integrated into various applications.
The "T&R" in its name refers to "tape and reel" packaging, commonly used for automated mounting in manufacturing processes. The device is suitable for use in consumer electronics, industrial applications, and any system requiring precise timekeeping. It operates on a low power supply, which makes it particularly useful in battery-operated devices.
