Maxim Integrated DS1245W-100+ Nonvolatile SRAM

The DS1245W-100+ from Maxim Integrated is a robust, high-performance 1Mbit Nonvolatile SRAM designed to deliver both the convenience of SRAM and the data retention capabilities of nonvolatile memory. This innovative memory solution is ideally suited for a wide array of applications that require frequent or rapid data access but cannot risk data loss in the event of a power failure.

At the heart of the DS1245W-100+ is its 128k x 8 nonvolatile static RAM, which operates from a single 5V supply. The access time of 100ns makes this memory component exceptionally fast, ensuring that data can be written and retrieved with minimal delay, which is crucial for high-speed computing and real-time applications.

One of the standout features of the DS1245W-100+ is its integrated lithium energy source and control circuitry that constantly monitors V<sub>CC for an out-of-tolerance condition. When such a condition is detected, the lithium energy source is automatically switched on and write protection is unconditionally enabled to prevent data corruption. This automatic switch to nonvolatile mode ensures that the data is preserved for over 10 years, providing long-term reliability without the need for an external battery.

The device is packaged in a 32-pin EDIP (Extended DIP) or PowerCap Module (PCM), which provides a highly reliable direct surface mount or socketable data storage solution. The DS1245W-100+ also includes features such as industrial temperature range operation, making it suitable for use in environments with extreme temperature conditions.

For ease of implementation, the DS1245W-100+ is designed to be pin-compatible with JEDEC standard 128k x 8 SRAMs, allowing for straightforward integration into existing designs without the need for extensive hardware modifications. This compatibility, combined with its nonvolatility and high-speed operation, makes the DS1245W-100+ an excellent choice for critical data storage applications in telecommunications, industrial control systems, and other electronic products that require data integrity and reliability.

Whether you're developing mission-critical systems or simply need a dependable memory component, the Maxim Integrated DS1245W-100+ offers a compelling solution that bridges the gap between volatile and nonvolatile memory requirements.
