Maxim Integrated Real Time Clock D:D:M:Y, 8-Pin SOP Surface DS1339AU+

Maxim Integrated DS1339AU+ real time clock (RTC) is a high-precision, 8-pin SOP surface mount IC designed for reliable and accurate timekeeping in industrial, consumer electronics, medical, office, and telecommunications applications. It supports a D:D:M:Y date format and operates within a voltage range of 1.71V to 5.5V, making it adaptable to various system designs.

The RTC accurately counts seconds, minutes, hours, day, date, month, and year, including automatic leap-year compensation up to the year 2200. It features two time-of-day alarms and a programmable square-wave output for versatile timing signals. The device can maintain time during power failures via a dedicated backup supply pin and includes power-fail detection and automatic switching, ensuring uninterrupted timekeeping.

Supporting crystals with up to 60kΩ ESR, the DS1339AU+ oscillator runs reliably down to 1.15V, facilitating low-voltage operation, and interfaces through a widely supported I2C serial interface, compatible with a broad range of microcontrollers.

This Real Time Clock IC finds applications in consumer electronics such as set-top boxes, digital recording devices, and network appliances; handheld devices including GPS and POS terminals; medical instruments like glucometers and medicine dispensers; office equipment including fax machines, printers, and copiers; telecommunications routers, switches, and servers; as well as industrial utility meters, vending machines, thermostats, and modems.
