Maxim Integrated Real Time Clock 7 bit Memory, 8-Pin SOP Surface, 1.71V-5.5V DS1339BU+

Maxim Integrated DS1339BU+ is a precise real-time clock IC with 7 bit memory designed for surface-mount applications. It fully manages timekeeping functions including time and date with leap year compensation effective up to the year 2100. Compatible with 8-pin SOP packages and operating with supply voltages ranging from 1.71V to 5.5V, this device is optimized for low power consumption to extend battery life in embedded systems.

The DS1339BU+ features two programmable time-of-day alarms and a programmable square-wave output, allowing flexible timing operations. It utilizes an I2C serial interface for easy communication with most microcontrollers, simplifying integration into consumer electronics, handheld devices such as GPS and POS terminals, medical instruments including glucometers and medicine dispensers, office equipment like fax machines and copiers, as well as telecommunications devices like routers and servers.

It provides automatic power-fail detect and switch circuitry with trickle-charge capability to ensure uninterrupted operation in critical applications. The product operates reliably across a broad temperature range from -40°C to 85°C, making it suitable for industrial and commercial environments. Its integrated crystal in a compact 8-pin SOP package reduces design complexity and PCB space.

Applications span consumer electronics, telecommunications, medical devices, office equipment, and other embedded systems requiring accurate and reliable timekeeping. This Maxim Integrated RTC device complies with general semiconductor standards but does not carry specific industry certifications.

Real-time clock counts seconds, minutes, hours, date, month, day of week, year with leap-year compensation. Two time-of-day alarms and programmable square-wave output included. I2C serial interface compatible with microcontrollers.

Low power operation with automatic power-fail detect and switch circuitry. Trickle-charge capability for battery backup extension. Wide temperature operation range from -40°C to 85°C. Compact 8-pin SOP surface-mount package with integrated crystal.
