Maxim Integrated DS1225AB-70IND+ Nonvolatile SRAM

The Maxim Integrated DS1225AB-70IND+ is a highly reliable, 64k Nonvolatile SRAM designed to provide a convenient and robust memory solution for industrial and mission-critical applications. This particular model offers a unique combination of volatile and non-volatile memory functionality, ensuring data preservation even in the event of a power loss.

Key Features

• Memory Size: The DS1225AB-70IND+ offers 64k of memory, which is organized as 8,192 words by 8 bits. This ample storage is ideal for applications requiring frequent and fast read/write operations with the added benefit of non-volatility.
• Access Time: With a 70ns access time, this device provides swift data retrieval, making it well-suited for performance-intensive applications where speed is critical.
• Nonvolatile Technology: The use of nonvolatile SRAM technology ensures that data is retained without the need for a battery backup. The integrated lithium energy source and control circuitry continuously monitor VCC for an out-of-tolerance condition. When such a condition occurs, the lithium energy source is automatically switched on and write protection is unconditionally enabled to prevent data corruption.
• Industrial Temperature Range: This device is designed to operate reliably in extreme environments with an industrial temperature range of -40°C to +85°C, making it suitable for industrial applications that may be exposed to harsh conditions.
• Package: The DS1225AB-70IND+ comes in a 28-pin EDIP (Encapsulated Dual In-line Package) or 300-mil SOIC (Small Outline Integrated Circuit) package, providing flexibility for various design requirements.
• Easy Integration: The pin-compatible nature of this SRAM allows for easy integration into existing systems without the need for significant redesigns or additional components.

Applications

The DS1225AB-70IND+ is suited for a wide range of applications that require the storage and retrieval of data in a reliable and efficient manner. These applications include industrial control systems, medical equipment, data loggers, and any other system where data integrity and retention are of utmost importance.

Maxim Integrated's commitment to quality and reliability is evident in the DS1225AB-70IND+, making it a smart choice for designers looking for a dependable nonvolatile memory solution.
