Maxim Integrated DS1258AB-70 Nonvolatile Memory

The DS1258AB-70 from Maxim Integrated is a high-performance, 3.3V, 1024k Nonvolatile (NV) SRAM with a built-in real-time clock (RTC). This memory module provides an efficient and reliable solution for applications requiring frequent or rapid access to stored data without the risk of data loss in case of power failure.

Key Features

• Nonvolatile SRAM Technology: Combines the access speed of SRAM with an internal lithium battery to maintain data integrity during power loss.
• Integrated Real-Time Clock: Features a full-function, real-time clock with an oscillator, which ensures accurate timekeeping even when the main power is off.
• Large Storage Capacity: Offers a significant 1024k memory capacity, ideal for storing critical data that must be preserved across power cycles.
• High-Speed Access: The DS1258AB-70 provides fast access times of 70ns, allowing for rapid data retrieval and storage.
• Automatic Battery Switchover: When main power is lost, the device automatically switches to battery power, ensuring continuous operation of the clock and data retention.
• Long Battery Life: Designed with a long-life battery that supports data retention for an extended period, making it suitable for long-term applications.
• Industrial Temperature Range: Operates across a wide temperature range, making it suitable for industrial applications subjected to harsh environments.

Applications

The DS1258AB-70 is ideal for a variety of applications where data integrity and timekeeping are critical, such as:

• Industrial control systems
• RAID systems
• Telecommunications equipment
• Medical devices
• Networking hardware

With its robust design, the DS1258AB-70 ensures that your system's data is always protected and available when needed. Its integration of both memory and real-time clock functions into a single package simplifies system design and reduces the number of required components, offering a cost-effective and space-saving solution for maintaining critical data and time information.
