The DS1230AB-120 is a 256k Nonvolatile SRAM designed by Maxim Integrated to provide a reliable data memory solution with the added assurance of non-volatility. This high-performance memory chip combines the access speed of static RAM with a non-volatile storage element, ensuring data preservation in the absence of power and eliminating the need for battery backup in many applications.

Key Features

• Memory Capacity: 256k (32k x 8-bit) provides ample space for critical data storage.
• Speed: The access time of 120 ns allows for fast data retrieval, making it suitable for high-speed operations.
• Power Failure Protection: An automatic power-fail chip deselect and write-protection circuit ensures data integrity during power transitions.
• Non-Volatile Storage: Data is automatically transferred to non-volatile storage and retrieved upon power-up, thanks to the integrated lithium energy source.
• 10 years Data Retention: The internal battery reliably maintains data for a minimum of 10 years in the absence of external power.
• Unlimited Write Cycles: Unlike EEPROMs, the DS1230AB-120 allows for an unlimited number of write cycles, enhancing its endurance.
• Directly TTL-Compatible: All inputs and outputs are fully compatible with TTL levels.

Applications

The DS1230AB-120 is ideal for a wide range of applications where data integrity and retention are crucial, such as:

• Industrial control systems
• RAID systems
• Telecommunications equipment
• Automotive electronics
• Medical devices

Reliability and Quality

Maxim Integrated's commitment to quality ensures that the DS1230AB-120 Nonvolatile SRAM is manufactured to the highest standards. It is designed to withstand harsh industrial environments and is rigorously tested to guarantee performance and durability.

With its combination of speed, reliability, and non-volatile storage capabilities, the DS1230AB-120 is the ideal choice for systems that require frequent or rapid data access but cannot risk data loss in the event of a power failure.
