Maxim Integrated DS1647P-120+ Timekeeping RAM

The DS1647P-120+ is a high-performance, full-function timekeeping RAM product designed by Maxim Integrated. This innovative component integrates a full-featured real-time clock (RTC) and a 32K x 8 nonvolatile static RAM in a single package. It is specifically engineered to provide a reliable and durable timekeeping solution, along with a significant amount of NV SRAM storage, making it an ideal choice for a wide range of applications in computing, industrial, telecommunications, and consumer electronics.

One of the key features of the DS1647P-120+ is its built-in real-time clock, which maintains seconds, minutes, hours, day, date, month, and year information. The RTC provides a leap-year compensation valid up to 2100, which is crucial for long-term accuracy and reliability. The clock operates in either 24-hour or 12-hour format with an AM/PM indicator, catering to different user preferences and international standards.

The DS1647P-120+ comes with an integrated crystal oscillator with a precise 32.768kHz output, ensuring minimal drift over time and temperature variations. The device also includes a programmable interrupt function that can be used for various purposes, such as wakeup calls or alarms, adding to its versatility.

Maxim Integrated has designed the DS1647P-120+ with data integrity in mind. The nonvolatile SRAM is automatically protected during power loss by an energy-efficient lithium battery, which can provide over 10 years of data retention and clock functionality. This feature is critical for applications where data loss cannot be tolerated, such as in embedded systems, data loggers, and other mission-critical devices.

With its 120ns access time, the DS1647P-120+ offers high-speed memory access, which is essential for applications that require quick data retrieval and storage. The product is available in a power-dissipating, 34-pin PowerCap Module (PCM) package, which makes it easy to integrate into various circuit board designs.

Overall, the Maxim Integrated DS1647P-120+ Timekeeping RAM is a robust and reliable component that combines the functionality of a real-time clock and nonvolatile memory, offering a comprehensive solution for timekeeping and data storage needs.
