The DS1554W-120IND+ is a full-function, year-2000-compliant (Y2K), real-time clock/calendar (RTC) with an integrated 512k NV SRAM from Maxim Integrated. This high-performance product is designed to maintain accurate time and date information, as well as provide a nonvolatile memory storage solution for industrial and mission-critical applications.

Operating over an industrial temperature range of -40°C to +85°C, the DS1554W-120IND+ is encased in a robust 34-Pin PowerCap Module package, ensuring its reliability and durability in challenging environments. The device is powered by a replaceable lithium battery, which allows it to retain data and keep the clock functioning for a minimum of 10 years in the absence of external power.

The RTC provides a century byte that rolls over from 1999 to 2000, and leap year compensation is valid up to the year 2100. It features a programmable alarm, interrupt function, and a programmable square wave output, making it highly adaptable for complex timing tasks. The clock accuracy is maintained within ±2 minutes/month at 25°C.

The DS1554W-120IND+ includes a 32.768 kHz crystal, which is the standard frequency for timekeeping, and it communicates with a microprocessor via a simple multiplexed byte-wide interface. The integration of nonvolatile SRAM allows for quick and unlimited read/write cycles, making it an ideal choice for applications that require frequent data updates or logging.

This product is widely used in telecommunications, embedded systems, servers, and other industrial applications where maintaining accurate time is crucial. Its robust design and integrated features make it a reliable choice for system designers who require a secure and long-lasting timekeeping solution.

The DS1554W-120IND+ is a testament to Maxim Integrated's commitment to providing high-quality, integrated circuit solutions for complex industrial applications.
