The DS1225AD-200 from Maxim Integrated is a 64k Nonvolatile SRAM designed to provide a highly reliable data storage solution that combines the access speed of static RAM with the non-volatility of ROM. This innovative memory chip is a perfect fit for applications that require data to be preserved across power cycles without the need for an external battery.

Key Features

• Capacity: The DS1225AD-200 offers a substantial 64 kilobytes (k) of memory, which is organized as 8k x 8 bits, making it suitable for storing a wide range of data types.
• Speed: With a 200ns access time, this device provides swift read and write operations, ensuring efficient performance in time-sensitive applications.
• Nonvolatile Storage: The integrated nonvolatile elements of the memory ensure that data is retained when power is removed, eliminating the need for a battery to maintain the data integrity.
• Unlimited Write Cycles: Unlike EEPROMs, the DS1225AD-200 allows for an unlimited number of write cycles, which enhances the chip's durability and lifespan.
• Automatic Recall: Upon power-up, the internal circuitry automatically transfers data from nonvolatile elements to the SRAM cells, which simplifies the recovery of stored data.
• Automatic Store: The memory chip automatically stores data when power is turned off, ensuring that all recent changes are preserved without any user intervention.
• Power Supply: The DS1225AD-200 operates on a single 5V power supply, which is a standard in many electronic systems, making it easy to integrate into existing designs.

Applications

The DS1225AD-200 is ideal for a variety of applications that require reliable and durable nonvolatile memory. It is commonly used in:

• Data logging systems
• Industrial control systems
• Medical equipment
• RAID systems
• Telecommunications

Maxim Integrated's commitment to quality and reliability is evident in the DS1225AD-200 Nonvolatile SRAM, making it a trusted choice for engineers and designers looking for a robust memory solution.
