Maxim Integrated DS1225Y-200 Nonvolatile SRAM

The DS1225Y-200 is a 64k Nonvolatile SRAM designed by Maxim Integrated to provide a reliable and durable memory solution for applications that require data preservation upon power loss. This high-performance, 200ns access time memory integrates a full 64k x 8 static RAM with a nonvolatile quantum trap storage element for each memory cell. The DS1225Y-200 combines the access speed of static RAM with the non-volatility of ROM, ensuring data integrity and instant recall of memory contents upon power-up.

Featuring a wide voltage range of 4.5V to 5.5V, the DS1225Y-200 is versatile for use in various systems. It is particularly well-suited for use in systems that are subjected to harsh environments or require long-term reliability, such as industrial controllers, robotics, and medical equipment. The nonvolatile feature of this SRAM makes it an ideal choice for critical data storage applications where the loss of data could be detrimental, such as configuration storage, real-time clocks, and other mission-critical data.

The device operates in two modes: read/write access like a standard SRAM and nonvolatile data-recall mode. The recall mode is initiated by a software command or automatically upon power-up, ensuring that data is available immediately after the device is powered. Additionally, a store operation can be initiated by software command or automatically at power-down, which transfers the data from the SRAM to the nonvolatile cells.

Designed with a standard 28-pin DIP package, the DS1225Y-200 is easy to integrate into existing designs. It is also available in surface-mount versions, providing flexibility for various PCB layouts. The high-reliability and long service life of the DS1225Y-200 make it an excellent choice for applications where frequent battery replacement is impractical or impossible.

Overall, the DS1225Y-200 from Maxim Integrated is a robust memory solution that combines speed, nonvolatility, and ease of use to meet the requirements of a wide range of applications where data integrity is paramount.
