IC RTC CLOCK/CALENDAR I2C 8UMAX

Manufacturer: Analog Devices Inc./Maxim Integrated

Categories: Real Time Clocks

Quality Control: Learn More

The Analog Devices Inc./Maxim Integrated DS1337U is a low-power real-time clock (RTC) and calendar IC. It features an I2C (2-Wire Serial) interface for communication and provides accurate timekeeping with a typical current consumption of 0.6µA at 1.3V to 1.8V. This component supports both 12-hour and 24-hour time formats, along with YY-MM-DD-dd date formatting. Key features include a programmable alarm, leap year compensation, and a square wave output. The DS1337U is available in an 8-pin uMAX/uSOP package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C, making it robust for various environments. This device is commonly utilized in industrial automation, consumer electronics, and medical device applications requiring precise time tracking.

Integrated Circuit FAQs

An integrated circuit (IC) is a semiconductor chip that contains transistors, resistors, capacitors, and other electronic components on a single silicon substrate. ICs are the foundation of modern electronics and power devices such as smartphones, computers, automotive systems, and industrial equipment.

Integrated circuits work by routing electrical signals through microscopic semiconductor components fabricated onto a silicon chip. Depending on the design, ICs can process, amplify, store, or control electronic data.
