Maxim Integrated DS1339C-33# Real-Time Clock

The DS1339C-33# is a high-performance, low-power serial real-time clock (RTC) with a built-in 32.768kHz crystal oscillator from Maxim Integrated. This compact and efficient device provides a full binary-coded decimal (BCD) clock/calendar that is accessible via a simple I2C interface. It is designed to address the needs of a wide range of applications requiring accurate timekeeping and efficient power management.

The DS1339C-33# offers a multitude of features that make it an ideal choice for embedded systems. Its timekeeping functions include seconds, minutes, hours, day, date, month, and year information, with the added capability of automatic leap year compensation valid up to the year 2100. Additionally, it provides two programmable time-of-day alarms and a programmable square-wave output, allowing it to serve as a versatile time management unit for any embedded system.

One of the key advantages of the DS1339C-33# is its low power consumption. The device operates in the 2.3V to 5.5V range, making it suitable for battery-powered applications. Its power-saving feature is further enhanced by an automatic power-fail detect and switch circuitry that ensures the continuation of timekeeping in the event of power loss.

The DS1339C-33# is housed in a compact 8-pin SO package, which is designed to occupy minimal space on a PCB. This, combined with its surface-mount form factor, makes it easy to integrate into various designs without the need for additional external components, such as a crystal or backup battery.

For developers and engineers looking to incorporate reliable timekeeping into their systems, the DS1339C-33# provides a convenient and robust solution. Its ease of use, coupled with Maxim Integrated's reputation for quality, ensures that this RTC will maintain accurate time and date information, contributing to the overall reliability and functionality of the end product.
