Maxim Integrated DS1225Y-100IND Nonvolatile SRAM

The Maxim Integrated DS1225Y-100IND is a robust, high-capacity 64k Nonvolatile SRAM designed to provide reliable data retention while eliminating the complexities, overhead, and system level reliability problems caused by backup batteries. This memory device offers an intelligent solution for critical data storage applications that require the data to be preserved across power outages without the need for an external battery.

With a storage capacity of 64K x 8 bits, the DS1225Y-100IND provides ample space for vital data. It operates with a supply voltage of 5V and features an access time of 100 ns, ensuring fast data retrieval and storage which is crucial for high-performance applications. The device is particularly suitable for use in industrial environments, as denoted by the "IND" suffix, which indicates its industrial temperature range rating.

This nonvolatile SRAM achieves its data retention capabilities through the use of an internal lithium energy source and a quartz crystal, which together maintain data for a minimum of 10 years in the absence of external power. The integration of the energy source and the crystal into the device's encapsulation not only saves space but also simplifies the design process for system engineers.

The DS1225Y-100IND is packaged in a 28-pin, 600-mil EDIP (Extended Dual In-line Package) which is known for its durability and ease of handling. The device also incorporates an automatic power-fail chip deselect and write protection, ensuring that data is not corrupted during power transitions.

Maxim Integrated's commitment to high-quality and reliability is evident in the DS1225Y-100IND, making it an excellent choice for applications such as real-time clocks, calibration data storage, system configuration parameters, and any other systems where the preservation of data is critical and battery maintenance is undesirable or impractical.

Overall, the DS1225Y-100IND offers a practical, maintenance-free solution for permanent and secure data storage, ensuring peace of mind for designers and users alike.
