Maxim Integrated DS1338Z-33+T&R Real-Time Clock (RTC)

The Maxim Integrated DS1338Z-33+T&R is a highly integrated, low-power serial real-time clock (RTC) with a built-in 32.768kHz crystal oscillator. This compact and efficient device provides a full binary-coded decimal (BCD) clock/calendar that is accessible through an I2C interface. The DS1338Z-33+T&R is designed to maintain accurate timekeeping when main power to the device is interrupted, making it an ideal choice for a wide range of applications where precise timekeeping is essential, such as in embedded systems, network servers, data loggers, and industrial equipment.

Featuring a simple and versatile design, the DS1338Z-33+T&R offers numerous benefits, including a low power consumption that extends battery backup run time. It operates over a wide voltage range of 2.0V to 5.5V, which allows it to be used in various system designs without the need for additional power regulation. Furthermore, the device includes a battery-backup input that automatically switches to the backup supply when main power is lost, ensuring the clock continues to run without interruption.

The DS1338Z-33+T&R supports a 400kHz I2C bus, which enables easy integration into existing systems with minimal interfacing required. The clock/calendar functionality provides seconds, minutes, hours, day, date, month, and year information, with automatic leap year compensation valid up to the year 2100. In addition, the device includes a programmable square-wave output that can be used for various applications, such as a system wake-up signal or as a reference clock.

Encased in a compact 8-pin SOIC package, the DS1338Z-33+T&R is supplied on tape and reel (T&R), which facilitates efficient handling and placement during automated manufacturing processes. Maxim Integrated's commitment to quality ensures that the DS1338Z-33+T&R provides a reliable and durable timekeeping solution that meets the rigorous demands of modern electronic systems.

Overall, the DS1338Z-33+T&R from Maxim Integrated is an excellent choice for designers looking for a cost-effective, high-performance RTC solution that is easy to use and provides long-term reliability.
