Maxim Integrated DS1250Y-150 Nonvolatile Memory

The Maxim Integrated DS1250Y-150 is a high-performance, 4096k Nonvolatile SRAM with a full 32-bit data bus. It offers a convenient and reliable solution for preserving critical data in a variety of applications. The DS1250Y-150 combines the access speed of static RAM with a nonvolatile storage component to ensure data integrity without the need for battery backup during power loss.

This robust memory module features a lithium energy cell that can maintain data retention for over 10 years, making it an ideal choice for systems that require long-term data preservation. The DS1250Y-150 operates over an industrial temperature range, which ensures functionality and reliability even in the most demanding conditions.

The DS1250Y-150 integrates an automatic power-fail chip-enable circuitry that switches on when the Vcc power supply drops below a certain threshold, allowing the device to write-protect the memory, thus securing the data during power-down events. Upon power-up, the circuitry disables write operations to prevent data corruption as the power stabilizes.

Key features of the DS1250Y-150 include:

• 4-Megabit (512k x 8) Nonvolatile SRAM
• Read and write access times of 150ns
• Unlimited write cycles and read cycles
• Lithium energy cell with over 10 years of data retention
• Automatic power-fail chip-enable circuitry
• Industrial temperature range operation
• JEDEC standard 32-pin DIP package

This memory module is particularly suited for use in systems that cannot tolerate data loss from power outages or system crashes, such as RAID systems, industrial control systems, and other mission-critical applications. The DS1250Y-150's nonvolatility eliminates the complexities, overhead, and additional components that battery-backed SRAMs require.

With the DS1250Y-150, Maxim Integrated continues its tradition of providing reliable, high-quality integrated circuits that meet the stringent requirements of industrial and commercial applications.
