The Maxim Integrated DS1225AD-70IND is a 64k Nonvolatile SRAM designed to provide a reliable and durable memory solution for applications requiring high-performance data retention. This particular model offers a storage capacity of 64K x 8 bits, making it an ideal choice for a wide range of data storage needs in industrial, military, and aerospace applications where the operational temperature ranges are critical.

With an access time of 70ns, the DS1225AD-70IND provides swift read and write capabilities, ensuring efficient data handling in time-sensitive operations. The integration of nonvolatile elements means that data is retained even when the power is turned off, thanks to the onboard lithium energy source that guarantees a data retention period of over 10 years.

This SRAM is designed to be fully compatible with a 28-pin, 600-mil DIP socket and operates across an industrial temperature range of -40°C to +85°C, making it suitable for harsh environments. The device also features an automatic power-fail chip deselect and write protection, ensuring data integrity during unexpected power loss situations.

Key features of the DS1225AD-70IND include:

• 64K x 8 nonvolatile static RAM
• 70ns access time
• Industrial temperature range (-40°C to +85°C)
• Over 10 years of data retention
• Automatic power-fail chip deselect and write protection
• Directly replaces volatile static RAM or EEPROM
• Unlimited write cycles

The DS1225AD-70IND is a reliable choice for systems that cannot tolerate data loss from power outages or systems that require the endurance to handle an unlimited number of write cycles. Its rugged design and nonvolatile memory technology make it an essential component for maintaining data integrity and ensuring the longevity of critical data storage.

Maxim Integrated's commitment to quality and reliability is evident in the DS1225AD-70IND, offering a robust memory solution for industries that demand the highest standards in data retention and memory performance.
