Maxim Integrated DS1225AB-85 Nonvolatile SRAM

The Maxim Integrated DS1225AB-85 is a 64k Nonvolatile SRAM designed to provide a reliable and durable data storage solution. This high-performance memory module combines the convenience of static RAM (SRAM) with a nonvolatile storage component, ensuring data retention without the need for a battery backup. The DS1225AB-85 offers a unique blend of speed and security for applications requiring fast access to data and long-term data preservation.

With a 64K x 8-bit structure, this nonvolatile SRAM provides ample space for storing critical data. The access time of 85ns makes it suitable for high-speed microprocessor systems, ensuring quick read and write operations that are essential for efficient processing. The integrated nonvolatile element is automatically engaged when power is lost, transferring the data from the SRAM to the nonvolatile storage in a seamless and secure manner. When power is restored, the data is transferred back to the SRAM, allowing normal operation to resume without data loss.

One of the key features of the DS1225AB-85 is its ease of use. It is directly compatible with a 28-pin 600-mil DIP socket and does not require any additional software or hardware changes to implement. This plug-and-play functionality makes it an ideal upgrade for systems requiring nonvolatile memory solutions with minimal design modifications.

The device is equipped with a precision voltage-monitor circuit that constantly monitors VCC. When an out-of-tolerance condition occurs, the internal lithium energy source is automatically switched on and write protection is unconditionally enabled to prevent data corruption. This ensures the integrity of the data stored within the device, even under adverse conditions.

Maxim Integrated's commitment to quality and reliability is evident in the DS1225AB-85. It is designed for applications where the data is paramount and must be preserved across power cycles, such as in industrial control systems, medical equipment, and other mission-critical devices. The integration of nonvolatile technology with the speed of SRAM makes the DS1225AB-85 a superior choice for designers seeking a robust memory solution.
