Maxim Integrated DS1220AB-150IND+ Nonvolatile SRAM

The DS1220AB-150IND+ is a high-performance, 16k Nonvolatile (NV) SRAM with a 10-year minimum data retention in the absence of external power. Designed and manufactured by Maxim Integrated, a leader in analog and mixed-signal engineering, this product offers the ideal combination of nonvolatile data security and the high speed and ease of use of a fast SRAM.

With its access time of 150ns, the DS1220AB-150IND+ provides a very fast read and write operation, making it suitable for a wide range of applications where data must be protected from power loss. This includes industrial control systems, RAID applications, telecommunications, and any other systems that require the retention of critical data upon power failure.

The nonvolatile functionality is ensured by an internal lithium energy source and control circuitry which automatically transfers data from SRAM to the internal nonvolatile memory when power loss is detected, and automatically restores it when power is returned. This process is transparent to the user, requiring no intervention or additional components to manage the transfer, making the DS1220AB-150IND+ a reliable and user-friendly choice for mission-critical applications.

Encased in a durable, industrial-grade package, the DS1220AB-150IND+ is designed to withstand harsh environments and is rated for industrial temperature ranges (-40°C to +85°C), ensuring consistent performance across a wide spectrum of conditions. The 24-pin DIP (Dual In-line Package) makes it compatible with standard sockets and easy to integrate into existing designs.

Key features of the DS1220AB-150IND+ include:

• 16K x 8 nonvolatile static RAM
• 150ns access time
• Automatic nonvolatile store on power loss
• Automatic recall on power-up
• 10-year minimum data retention in the absence of external power
• Industrial temperature range (-40°C to +85°C)
• Reliable Direct Write™ cell
• 24-pin DIP package

With its robust design and dependable nonvolatile memory technology, the Maxim Integrated DS1220AB-150IND+ is an excellent choice for designers looking to incorporate secure data storage into their industrial or high-reliability systems.
