Introducing the DS1744W+P12 from Maxim Integrated

The DS1744W+P12 is a high-performance, full-function Nonvolatile (NV) Timekeeping RAM designed and manufactured by Maxim Integrated, a leader in the development of innovative analog and mixed-signal products. This state-of-the-art component integrates a full-featured real-time clock (RTC), 32K x 8 nonvolatile static RAM, power-fail control circuit, and battery all in a single package. It is a perfect solution for applications requiring reliable timekeeping and data storage that can endure power loss without data corruption.

Key Features

• Real-Time Clock (RTC): The DS1744W+P12 includes a highly accurate RTC with a century byte to provide year 2000 compliance and beyond. It maintains seconds, minutes, hours, day, date, month, and year information, with automatic leap year compensation up to 2100.
• Nonvolatile Memory: The integrated 32K x 8 NV SRAM offers data retention without the need for a battery during power loss, ensuring data integrity and reducing the risk of data loss.
• Power-Fail Control: The device features a power-fail control circuit that automatically writes-protects the nonvolatile memory when the VCC supply falls below a predetermined threshold, ensuring the preservation of data during power failures.
• Integrated Battery: The onboard lithium energy cell can maintain data and real-time clock operation for over 10 years in the absence of external power.
• Package: The module is housed in a 24-pin 300-mil EDIP or 28-pin 600-mil SOIC package, providing a compact solution for space-constrained applications.
