Maxim Integrated DS1225Y-200+ Nonvolatile SRAM

The DS1225Y-200+ is a high-performance, 64K Nonvolatile SRAM module designed and manufactured by Maxim Integrated. This component provides an efficient memory solution that combines the access speed of static RAM with the non-volatility of ROM. It is an ideal choice for a wide range of applications that require data to be preserved in the absence of power, such as industrial control systems, data logging devices, and critical system parameter storage.

The DS1225Y-200+ offers a substantial memory capacity of 64 kilobytes, organized as 8,192 words by 8 bits. It operates at a speed of 200ns, ensuring rapid data access and retrieval, which is crucial for time-sensitive applications. This speed is particularly beneficial for systems that cannot tolerate long delays when reading or writing data.

One of the key features of the DS1225Y-200+ is its fully static operation, which eliminates the need for external clocks or timing strobes. This simplifies system design and reduces the potential for timing-related errors in data transactions. Additionally, the device uses CMOS technology, which ensures low power consumption, thereby extending the life of battery-powered devices.

The nonvolatile aspect of the DS1225Y-200+ is achieved through the integration of a lithium energy source and control circuitry that automatically switches the device to a nonvolatile mode during power loss. This feature guarantees that all data is retained for over 10 years in the absence of power, providing peace of mind for applications where data integrity is critical.

This memory module is also designed with ease of implementation in mind, featuring a JEDEC standard 28-pin DIP (dual in-line package) that is compatible with most socketed or soldered memory interfaces. Furthermore, the DS1225Y-200+ is designed to be both write-protectable and directly replaceable with other standard 8k x 8 static RAMs, offering flexibility and ease of integration into existing systems without the need for redesign.

In summary, the Maxim Integrated DS1225Y-200+ Nonvolatile SRAM is a robust, high-speed memory solution that ensures data preservation and reliability for a multitude of applications that require nonvolatile memory storage.
