Maxim Integrated DS1744WP-120+ Nonvolatile Timekeeping RAM

The Maxim Integrated DS1744WP-120+ is a state-of-the-art, high-precision timekeeping RAM that combines a full-featured real-time clock (RTC) with a 32K x 8 nonvolatile static RAM. This innovative component is designed to provide reliable timekeeping, data retention, and easy integration into a wide range of applications, particularly those requiring battery-backed nonvolatile memory and an accurate RTC.

The DS1744WP-120+ operates with a voltage range of 4.5V to 5.5V and is particularly well-suited for systems that must maintain accurate time and date information even in the event of a power failure. The integrated lithium energy source ensures long-term data retention and clock functionality for over 10 years in the absence of external power.

One of the key features of this product is its integration of the RTC, which includes a quartz crystal and registers for seconds, minutes, hours, day, date, month, and year. The RTC is designed to be accurate to ±1 minute per month at 25°C, making it highly reliable for time-sensitive applications. Additionally, the clock automatically adjusts for months with fewer than 31 days, including corrections for leap year.

The DS1744WP-120+ is housed in a robust, 28-pin EDIP (Electrically Erasable Programmable Read-Only Memory Dual In-line Package) that is waterproof, ensuring its performance in a variety of environmental conditions. The nonvolatile RAM feature allows for quick and unlimited read/write cycles, making it an ideal choice for applications that require frequent or rapid data updates without the risk of data loss.

With a typical active current of only 2mA and a standby current of 1µA, the DS1744WP-120+ is energy-efficient, which is critical for battery-powered applications. Its simple parallel interface facilitates easy integration into existing designs, and the device supports a full static operation, meaning that addresses and data can remain valid for the entire read/write cycle.

In summary, the Maxim Integrated DS1744WP-120+ is a robust and reliable solution for applications that require accurate timekeeping and data storage without the worry of data loss during power failures. Its waterproof packaging, long-term battery life, and high data integrity make it a top choice for a variety of critical applications.
