Maxim Integrated DS1338Z-18+T&R Real-Time Clock

The DS1338Z-18+T&R from Maxim Integrated is a highly precise, full-featured real-time clock (RTC) module, designed to provide a comprehensive timekeeping solution for a wide range of applications. This RTC module is ideal for use in embedded systems, industrial controllers, consumer electronics, and any other system that requires an accurate time base for operation.

Featuring a built-in 32.768 kHz crystal oscillator, the DS1338Z-18+T&R maintains accurate timekeeping with minimal external components. It includes a battery-backup input that allows the device to continue keeping time even when the main power is lost, ensuring consistent timekeeping without interruption.

The device offers a multitude of functions, including hours, minutes, and seconds counters, as well as day, date, month, and year information with leap year compensation valid up to the year 2100. This ensures that the DS1338Z-18+T&R will provide reliable time data for decades to come.

Communication with the DS1338Z-18+T&R is facilitated through an I²C serial interface, which allows for simple integration into existing designs without the need for complex interfacing. This makes it an excellent choice for systems where ease of integration and minimal design changes are essential.

Available in a compact 8-pin SOIC package, the DS1338Z-18+T&R is suitable for space-constrained applications. The "+T&R" designation indicates that this product is provided in tape and reel packaging, which is optimized for automated pick-and-place manufacturing processes, making it an ideal choice for high-volume production.

Key features of the DS1338Z-18+T&R include:

• Battery-backed, nonvolatile (NV) timekeeping
• Low power consumption
• 56-byte, battery-backed NV RAM for data storage
• Automatic power-fail detect and switch circuitry
• Programmable square-wave output signal
• Simple serial interface (I²C)
• Industrial temperature range (-40°C to +85°C)

The DS1338Z-18+T&R from Maxim Integrated is a robust and reliable RTC solution that offers precision and durability for systems where timekeeping is critical. Its combination of features and ease of use make it a versatile choice for designers and engineers looking to enhance their products with accurate time and date functionality.
