Maxim Integrated DS1646-120 Nonvolatile Timekeeping RAM

The Maxim Integrated DS1646-120 is a state-of-the-art nonvolatile timekeeping RAM module that combines a full-featured, battery-backed real-time clock (RTC) with 128k x 8 nonvolatile static RAM. This innovative module is designed to maintain accurate time and preserve data integrity even when the primary power source is compromised, making it an ideal solution for systems that require reliable timekeeping and data retention capabilities.

At the heart of the DS1646-120 is a precision RTC that provides detailed timekeeping features, including seconds, minutes, hours, day, date, month, and year information. The clock is accurate to ±1 minute per month at 25°C, ensuring that your system maintains accurate time over extended periods. The integrated leap year compensation is valid up to the year 2100, providing a long-term, maintenance-free operation.

The nonvolatile SRAM in the DS1646-120 is designed to retain data without the need for an external battery. The module automatically switches to its internal lithium battery when the external power supply drops below a threshold, preserving stored data and maintaining the clock operation. This automatic backup feature provides peace of mind, as data integrity is maintained even in the event of unexpected power loss.

Engineered for durability and longevity, the DS1646-120 is encased in a 34-pin PowerCap Module (PCM) package, which not only protects the internal circuitry but also ensures a secure connection to the motherboard. The module's design allows for easy surface mounting, making it suitable for a wide range of applications, including telecommunications, industrial systems, and embedded computing platforms.

With its combination of nonvolatile memory, integrated RTC, and robust packaging, the Maxim Integrated DS1646-120 is a versatile component that provides a reliable solution for systems requiring persistent data storage and precise timekeeping. It is a testament to Maxim Integrated's commitment to delivering high-quality, innovative products that meet the demanding needs of today's technology landscape.
