The DS1744-70IND+ is a robust, high-performance nonvolatile timekeeping RAM module from Maxim Integrated, designed to provide a reliable and durable solution for systems that require battery-backed SRAM and an integrated real-time clock (RTC). This innovative component is particularly suitable for industrial applications where stable and continuous timekeeping is critical, even during power loss.

Key Features

• Integrated Power-Fail Deselect Circuitry: The DS1744-70IND+ comes equipped with internal circuitry that automatically switches to the battery supply when a power failure is detected, ensuring data integrity and continuous timekeeping.
• Real-Time Clock: The device includes a full-function, binary-coded decimal (BCD) clock/calendar that is accessible via a simple multiplexed byte-wide interface. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information.
• Nonvolatile SRAM: With 32KB of nonvolatile static RAM, users can store data that will not be lost when the system power is removed. This feature is essential for maintaining critical data logs and system state information.
• High Reliability: Designed with industrial applications in mind, the DS1744-70IND+ operates within an extended temperature range of -40°C to +85°C, making it ideal for harsh environments.
• Long Battery Life: The component's energy-efficient design ensures an extended battery life, which is crucial for long-term deployment in fields where regular maintenance is not feasible.
• Simple Integration: The module's 28-pin, 600-mil DIP package allows for easy integration into existing systems without the need for complex wiring or additional components.

Applications

The DS1744-70IND+ is particularly well-suited for a wide range of industrial applications, including:

• Embedded systems
• Utility meters
• Industrial controllers
• Point-of-sale terminals
• Network servers and other telecommunications equipment

With its combination of nonvolatile memory, integrated RTC, and robust design, the Maxim Integrated DS1744-70IND+ is a comprehensive solution for systems that cannot afford to lose time or data, ensuring seamless operation and reliability in the most demanding conditions.
