Maxim Integrated DS1220Y-200 Nonvolatile SRAM

The Maxim Integrated DS1220Y-200 is a high-performance, 16k Nonvolatile SRAM designed to provide a reliable and durable data storage solution in a myriad of applications. This innovative memory chip incorporates a full 16-Kilobyte (Kb) of static RAM with a nonvolatile quantum trap storage element integrated within each static memory cell. The DS1220Y-200 offers a unique combination of volatile and nonvolatile memory, ensuring data preservation even when power is lost, without the need for an external battery.

With access times as fast as 200 nanoseconds, the DS1220Y-200 provides the speed of a traditional SRAM, making it suitable for high-speed data acquisition, storage, and processing. Its direct interface to microprocessors is facilitated by an industry-standard JEDEC pinout, which allows for easy integration into existing systems without the need for significant redesign.

The nonvolatile feature of the DS1220Y-200 is transparent to the user, with no additional write cycles required to store data permanently. This is achieved through an automatic internal transfer of data to and from the nonvolatile storage upon power-down and power-up, respectively. This process ensures data integrity and eliminates the need for routine battery maintenance, thus reducing the total cost of ownership over the product's lifespan.

Key features of the DS1220Y-200 include:

• 16K x 8 nonvolatile static RAM
• 200 ns access time
• Automatic nonvolatile store on power loss
• Nonvolatile store and recall modes
• 10 years of data retention in the absence of power
• Unlimited read and write cycles to SRAM
• JEDEC standard 24-pin DIP package
• Compatible with 5V ±10% power supply
• Commercial and industrial temperature ranges

The DS1220Y-200 is ideal for applications that require fast and frequent writes to memory with the added security of nonvolatile storage to prevent data loss. This includes but is not limited to industrial control systems, utility meters, medical devices, and other critical data logging applications. Maxim Integrated's commitment to quality and reliability ensures that the DS1220Y-200 is a top choice for designers looking for a robust and enduring nonvolatile SRAM solution.
